Verdict: December and November are your highest-volume months, but your cause's peak season may look different. Plan your full calendar around data, not assumptions.
What works: Aligning appeals with natural giving windows, using Tuesday/Wednesday sends, launching year-end campaigns early, and tailoring timing to your cause category.
What doesn't: Blasting appeals in July without a cultivation strategy, sending Friday emails expecting strong conversions, or applying generic industry averages to cause-specific campaigns.
Best for: Nonprofit fundraisers building or refining their annual giving calendar.
Worth considering if: Your cause is education, veterans, or faith-based — your peak season likely doesn't match the industry average.
Timing can turn an ordinary fundraising campaign into a remarkable one. Yet most nonprofits still plan their calendars around gut instinct rather than data.
December consistently delivers the highest donation volume, with over 30% of annual giving occurring in the final month. But that headline number hides important nuances. Your cause, your donor base, and your send timing all shift what "best time" actually means for you.
This guide breaks down the best months, days, and times to fundraise — with cause-level data, tactical approaches for every season, and a timing framework you can use to build a smarter annual calendar.
Zeffy analyzed donation transactions from thousands of nonprofits across 17 cause categories in 2024. Here's what we found about when people actually give — and why your cause's peak season might not match the industry average. See the full research

Why does timing matter for fundraising?
Helps understand natural donor-giving patterns
Understanding when your donors are most likely to give empowers your nonprofit to make data-driven campaign decisions. Rather than guessing at the best times to reach out, analyzing giving patterns reveals clear trends in donor behavior.
For example, data shows that some donors prefer making small monthly contributions, while others save their giving for specific annual events. Many corporate donors align their giving with fiscal quarters, and individual supporters often follow personal patterns tied to paydays or bonuses.
These insights help you move from random outreach to strategic engagement that respects and works with your donors' natural giving preferences.
Enables donors to plan their tax-deductible contributions
The end of the year drives charitable giving as donors are motivated to give before December 31st to secure tax deductions for the current year.
This makes December one of the most important months for fundraising. Nearly 30% of all annual donations take place in this month, with the last three days being especially lucrative.
Supports seasonal fundraising
When campaigns naturally align with donors' mindsets, response rates increase significantly. For example, education-focused appeals in August tap into parents' back-to-school preparations, while holiday campaigns leverage natural year-end generosity.
Summer might highlight youth programs, while winter could emphasize shelter and warmth initiatives. You should focus on matching your campaigns with seasonal moments to make your appeals meaningful and timely.
Prevents donor fatigue
Strategic campaign spacing helps prevent donor burnout while maximizing engagement. Research indicates that donors receive an average of 2-3 fundraising appeals per month from various organizations.
Here's what your nonprofit can do to stand out:
- Space major campaigns 8-12 weeks apart
- Limit email appeals to 2-3 per month
- Focus on personalized, high-impact communications
- Track response rates to identify the optimal frequency
Fundraising timing data: the best (and worst) times to ask for donations
Before diving into monthly strategies, here's something most fundraising guides skip. When you ask matters almost as much as how you ask. The framework below gives you concrete timing guidance by month, day of the week, and time of day — so you can build a calendar based on real patterns, not guesswork.
Monthly fundraising potential at a glance
The table below rates each month's fundraising potential based on donation volume patterns observed across nonprofits. Use it as a planning baseline before diving into the month-by-month tactics.
|
| January | Low | Sustainer upgrades, annual planning, donor stewardship |
| February | Low–Moderate | Valentine's giving, peer-to-peer campaigns, New Year momentum |
| March | Moderate | Spring momentum, Giving Days, awareness month alignment |
| April | Moderate | Tax deadline drives last-minute charitable giving |
| May | Moderate | Steady giving; strong for awareness months and outdoor events |
| June | Moderate | Fiscal year-end giving for some donor segments; community events |
| July | Low | Slowest month overall; focus on donor cultivation |
| August | Low–Moderate | Back-to-school campaigns, corporate partner sessions |
| September | Strong | Fall momentum; ideal time to launch year-end campaign warm-ups |
| October | Strong | High engagement; GivingTuesday pre-campaign outreach |
| November | Very High | GivingTuesday + early year-end appeals; major campaign window |
| December | Highest | Final week drives 30%+ of annual totals; tax deadline urgency |
December and November together account for a significant share of annual nonprofit donations for most organizations. Plan your calendar with that weight in mind. But don't write off the spring window. March through May is consistently underutilized by smaller nonprofits and offers real room to grow.

Best and worst days of the week to send fundraising appeals
Not all days are created equal. Here's how day-of-week performance breaks down for email appeals and donation pages.
- Tuesday — Consistently the top-performing day for email open rates and donation conversions. Donors have cleared Monday chaos and are in decision-making mode.
- Wednesday — A close second. Works especially well for mid-campaign update emails.
- Thursday — Strong for final-push and deadline-driven appeals ("Only 48 hours left").
- Monday — Below average. Inboxes are crowded and donors are focused on work priorities.
- Friday — Moderate performance. Works for casual social media appeals but weak for email.
- Saturday/Sunday — Surprisingly effective for emergency or emotional appeals when people have more time to read. Generally underperforms for standard campaigns.
For in-person events, Saturday evenings outperform Friday and weeknight alternatives for most cause categories. Donors are more relaxed, more likely to bring a guest, and more receptive to larger asks.
Best times of day to send donation appeals
Timing your send within the day can meaningfully lift open and click-through rates.
- 8:00–10:00 AM (local time) — The strongest window overall. Donors check email before their workday accelerates.
- 12:00–2:00 PM — A reliable secondary window. Lunch-break browsing drives solid engagement.
- 6:00–8:00 PM — Effective for peer-to-peer campaigns and social media pushes when donors are winding down.
- Avoid: Sending between 10 PM and 6 AM, or between 2:00 and 5:00 PM — the post-lunch productivity block when emails get buried.
How to use this data
These benchmarks are starting points, not rules. Your specific donor base may respond differently. A retired donor segment, for example, often engages strongly on weekend mornings. Run A/B tests over two to three campaigns to identify your organization's peak windows. Then build your annual calendar around those patterns rather than assuming industry averages apply universally.
Your cause's peak season might not be fall
Most fundraising guides treat November and December as the universal peak and leave it there. Zeffy's 2024 seasonal giving research — drawn from anonymized donation transactions across thousands of nonprofits in 17 cause categories — tells a more nuanced story.
Fall is the biggest giving season across all causes analyzed. But some causes tell a very different story.
Here's what that means in practice for four cause categories.
Education and youth development
Education-focused nonprofits often see a spring spike in March and April, as donors respond to end-of-school-year urgency messaging. Back-to-school campaigns in August also generate stronger-than-average performance for this category. If you rely only on a November year-end push, you're leaving spring donations on the table.
Veterans and military service organizations
Veterans organizations tend to see significant giving concentrated in fall — particularly around Veterans Day in November. November and the surrounding weeks represent a disproportionately large share of annual giving for this cause category. Planning a major campaign for this window isn't just good timing. It's where your donors are already primed to give.
Faith-based organizations
Faith-based giving often tracks liturgical and religious calendars rather than the secular giving calendar. Easter and Lent drive spring giving for many faith communities, and the end-of-year window remains strong. If you're building a calendar for a faith-based org, map your campaigns against your community's religious calendar first.
Animal welfare
Animal welfare organizations tend to see giving spikes tied to awareness moments — think pet adoption events, "Clear the Shelter" campaigns in August, and year-end giving. The summer window performs better for animal welfare than for many other cause types.
Before you build your annual calendar around industry averages, check whether your cause follows them. Zeffy's seasonal giving research breaks down donation patterns by cause category so you can plan from data that actually reflects your mission area.
Campaign launch timing: how to plan before you promote
Most nonprofits underestimate how much lead time a successful campaign needs. They focus on the public launch date and skip the groundwork that makes that launch land.
How far in advance to start planning
For a major year-end campaign, plan to start internal preparation 10 to 12 weeks before your public launch. That timeline covers goal-setting, messaging development, donor segmentation, creative assets, and board alignment. Compressing this to four weeks is one of the most common reasons year-end campaigns underperform.
For Giving Tuesday specifically, start your planning in September. Donor outreach and warm-up emails should begin at least three weeks before the day itself. Many nonprofits that struggle on Giving Tuesday treat it as a one-day sprint when it works best as a two-to-three week campaign with a single big day at the end.
The quiet phase vs. the public launch
High-performing campaigns use a two-phase structure. The quiet phase — sometimes called a soft launch or silent phase — runs before any public announcement. During this phase, you approach your closest major donors and board members privately and ask them to give early. This builds a giving base before the public sees the campaign.
When you launch publicly, you can open with a milestone already achieved ("We're already 40% of the way to our goal"). That social proof dramatically increases conversion for new donors who see the campaign for the first time.
Optimal campaign duration
Campaigns that run too long lose urgency. Campaigns that run too short don't build enough momentum. For most nonprofits, the sweet spot is 21 to 30 days for a major campaign, with a strong push in the final 48 to 72 hours.
The final three days of any time-limited campaign typically generate a disproportionate share of total donations. Build your communications calendar around that pattern. Send your most urgent, emotionally resonant appeal on day 28 or 29 — not day 1.
For smaller, single-event campaigns or day-of-giving drives, a seven-to-ten day window with daily social media and two to three emails tends to outperform both shorter and longer formats.
Which are the best months to fundraise for your nonprofit?
1. December
December offers the highest potential for fundraising, with December 29th to 31st being the most valuable days. The holiday season naturally inspires generosity, with many donors feeling motivated to support causes they care about. Many individuals also choose to donate just before the year's end to receive tax benefits.
Here are effective ways to maximize your December fundraising:
- Send personalized emails highlighting the top 3 achievements and specific impact metrics from the year.
- Include a clear CTA with tax benefit deadlines and matching gift opportunities.
- Create a holiday giving campaign centered around themes like "12 Days of Impact" or "Season of Hope." Launch daily social media spotlights featuring one beneficiary story and specific donation goal.
- Host hybrid events (virtual + in-person) with exclusive auction items.
- Partner with 3-5 local businesses for matched sponsorships or in-kind donations.
2. November
November kicks off serious year-end fundraising, with Giving Tuesday being the biggest opportunity. Nonprofits raised over $3.1 billion on this single day of giving in 2023.
Make the most of this momentum by:
- Starting your outreach early — don't wait until Giving Tuesday to engage donors
- Getting your board involved in reaching out to their networks
- Sharing quick stories about what donations actually do — people love seeing real impact
The key is to keep your message simple and focused on impact. For example: "Every $100 provides a week of meals for a family in need."
3. June
Summer offers unique opportunities to deepen donor relationships through hands-on engagement.
While donation volumes may be lower, these months are perfect for cultivating stronger connections through volunteer programs and community events. Focus on creating meaningful volunteer experiences that bring supporters closer to your mission.
Host engaging summer events that work:
- Family movie nights in local parks — partner with food trucks and set suggested donation amounts
- Community tournaments — get local businesses to sponsor teams and create friendly competition
- Father's Day campaign highlighting local heroes — let people share stories while making tribute donations
- Weekend workshops teaching useful skills — cooking classes or gardening tips with registration fees supporting your work
Fundraising opportunities in other months
1. January and February
Fundraising Potential: Low to Moderate
January and February see slower fundraising as companies and individuals focus on financial priorities and manage post-holiday expenses. They close their year-end accounts, prepare tax documents, and review their previous year's giving.
Here's what your nonprofit can do in these months:
- Review your nonprofit's performance last year to identify strengths and areas to improve. Analyze past campaigns, donor retention, fundraising totals, and engagement for effective strategies.
- Appeal to New Year's resolutions by showing how donations or volunteering can make a difference. Highlight how supporting your nonprofit helps fulfill goals of kindness and positive impact.
- Plan donor appreciation activities with personalized notes, impact updates, or thoughtful small gifts. Strengthen donor relationships through meaningful gestures that build lasting connections.
- Use these months to plan campaigns, update your online content, and prepare for the festive seasons. Focus on grant applications, fundraising efforts, and fresh content for the upcoming year.
2. March, April, and May
Fundraising Potential: Moderate to Good
Spring brings natural opportunities for outdoor events and community engagement. As the weather warms up, people are eager to participate in activities that bring them together.
This season is perfect for launching new initiatives and reconnecting with donors through interactive events that showcase your mission's impact.
Here's how you can raise funds during these months:
- Host a spring-cleaning drive to collect gently used items or monetary donations. Use this opportunity to introduce donors to your monthly giving program, highlighting how sustained support creates year-round impact.
- Partner with a travel agency to host a raffle featuring summer vacation packages. Allocate half the raffle proceeds to support your mission and initiatives.
- Organize an ice cream social to offer relief from the summer heat. Partner with a local vendor to sell scoops and frozen treats to raise money.
3. July and August
Fundraising Potential: Low to Moderate
July and August are usually considered less favorable fundraising months. In July, donors are focused on summer vacations and personal time. August is when people return to work routines, leaving less time for charitable activities.
Here are some of the ways to consider raising funds in these months:
- Host fireworks viewing parties, BBQs, or parades on July 4th to unite your community. Consider offering branded merchandise or suggested donation options while building community connections.
- Run breakfast sessions with corporate partners to share impact metrics and specific partnership opportunities.
- Create a back-to-school program where parents can buy supplies for their kids and sponsor supplies for students in need.
- Plan industry-focused networking events in August that combine relationship-building with clear donation opportunities.
4. September and October
Fundraising Potential: Strong
September and October present good fundraising opportunities as communities gather for fall festivals and Halloween celebrations.
Here are some ideas to consider for fundraising in these months:
- Launch after-school tutoring programs with local education experts, offering flexible payment plans for different income levels.
- Create date night fundraisers by partnering with restaurants — parents get dinner while kids enjoy supervised activities.
- Organize neighborhood-wide trick-or-treat drives where homes collect donations through QR codes and mobile giving.
- Set up fall carnival booths that combine seasonal activities with fundraising through vendor partnerships and sponsored games.
Best vs. worst times to fundraise: a quick-reference guide
Understanding when not to fundraise is just as valuable as knowing your peak windows. Here's a direct comparison to guide your planning.
|
| December 29–31 | Best days of the year | Tax deadline urgency + holiday generosity peak |
| Giving Tuesday (November) | Best single day | Highest single-day giving volume; national attention |
| Tuesday/Wednesday emails | Best send days | Highest open and conversion rates for appeals |
| 8–10 AM local time | Best send window | Donors check email before workday peaks |
| September–October | Strong | Fall momentum; ideal for campaign warm-ups |
| March–May | Underutilized opportunity | Smaller nonprofits consistently overlook this window |
| Early January | Avoid major asks | Post-holiday fatigue; donors managing financial reset |
| July | Worst overall month | Vacation season; lowest donation volume of the year |
| Friday emails | Use with caution | Moderate at best; weak for conversion-focused appeals |
| 2–5 PM sends | Avoid | Post-lunch productivity block buries emails |
| Competing national events | Plan around them | Major sporting events, elections, and news cycles suppress giving |
| Last-minute campaign launches | Avoid | Campaigns need 10–12 weeks of prep for major drives |
The "avoid" column is where most nonprofits lose ground they don't know they're losing. Sending a major appeal on a Friday afternoon in July isn't just low-impact. It trains donors to ignore your emails. Build rest periods into your calendar intentionally — and use the slow months for relationship-building rather than revenue targets.
Final words on the best time to fundraise
Build your nonprofit's success by planning your fundraising calendar around peak giving periods. December and November bring the highest donations, while spring and fall offer outdoor event opportunities. Use quieter months for planning and strengthening donor relationships.
Align your fundraising calendar with relevant observance days that resonate with your mission. Events such as the Pride Month Parade for LGBTQ+ organizations and Earth Day for environmental causes can create authentic opportunities to showcase your impact and engage supporters who care deeply about these issues.

FAQs on the best time to fundraise for nonprofit organizations
How can nonprofits create a fundraiser calendar?
A fundraising calendar guides your nonprofit's year-round efforts, aligns team activities, and captures every giving opportunity. Here's how you can create one: identify specific fundraising objectives such as revenue targets or donor growth; list major events, online campaigns, or initiatives for each month; include global giving events and relevant observance days that match your mission; determine which platforms or methods to use for each campaign; and set clear timelines, budgets, staff responsibilities, and periodic check-ins. Create a fundraising calendar for your nonprofit with our free template.
What is the biggest fundraising day of the year?
Giving Tuesday — the Tuesday after Thanksgiving — is the single biggest fundraising day for most nonprofits. Since 2012, it has grown into a global giving event. In 2023, it raised an estimated $3.1 billion for U.S. charities. The day marks the start of the giving season nationwide and is best treated as the finale of a two-to-three week campaign rather than a standalone day.
What is the best day of the week for a fundraiser?
Tuesday is consistently the top-performing day for email fundraising appeals and online donation conversions. Wednesday is a strong second choice. For in-person events, Saturday evenings tend to outperform other days because donors are relaxed, more likely to bring a guest, and more receptive to larger asks. Monday and Friday are generally the weakest days for email-based appeals.
How long should a fundraising campaign last?
For most nonprofits, 21 to 30 days is the sweet spot for a major campaign. Campaigns that run longer lose urgency; campaigns that run too short don't build enough momentum. The final 48 to 72 hours of any time-limited campaign typically generate a disproportionate share of total donations, so plan your most urgent communications for that closing window. For single-event or day-of-giving campaigns, a seven-to-ten day window with two to three emails and daily social content tends to perform well.
How can social media help with nonprofit fundraising?
Social media transforms how nonprofits connect with donors. These platforms turn one-way announcements into ongoing conversations, letting organizations share real-time impact stories and updates. Through strategic content and built-in giving tools, nonprofits can turn everyday supporters into active advocates. The key is consistency — share authentic moments, celebrate donor impact, and make giving feel natural rather than forced. When used effectively, social media creates a community of engaged supporters who amplify your message and mission. Read our guide on how to use social media for your nonprofit.
What are the worst months to launch a major fundraising campaign?
July is consistently the lowest-volume fundraising month across most cause categories. Early January is also challenging — donors are recovering from year-end giving and managing post-holiday finances. If you must run campaigns during these periods, focus on donor cultivation, sustainer upgrades, and relationship-building rather than aggressive acquisition or major revenue targets.
