Fill the calendar fundraiser
Fill the calendar fundraiser: every date claimed, $496 raised
The goal of a fill-the-calendar fundraiser is on the page for everyone to see: a month of open dates, and a calendar that is done when the last one is claimed. Each date is its number in dollars, $1 on the 1st, $17 on the 17th, $31 on the 31st, so a full 31-day calendar raises $496. Supporters watch it fill, and the last few dates always go fast.
This is 2026. Click and text. They pick a date and give. Gone are the days of planning a fundraiser three months out, printing a calendar and collecting cash by hand.
What a filled calendar raises
| Month | Dates to fill | Standard pricing | 2x pricing |

| April, June, September, November | 30 | $465 | $930 |

Those are per calendar. On a team calendar every participant has a calendar of their own to fill: 13 dancers raised $3,567 in 10 days, and a theatre booster club with 58 cast and crew raised $2,591 in 15 days.
How the calendar fills
- The first text. Share one link with the people closest to the cause. On the real calendars in our case studies the first gift landed within two hours, and the round dates and the last week of the month were claimed first.
- The middle. Every gift puts a name and a note on the calendar, so the page looks busier each time someone opens it. A supporter who wants a date that is gone picks another; the amounts are small and visible.
- The last ten dates. When ten or fewer are open, the calendar offers one tap to take every date that is left, which is how most calendars finish.
- Full. The page shows every name and message and thanks everyone. Supporters get a receipt by email the moment they give, and your organization keeps 100% of calendar dollars.
Filling more than one calendar
A small team gives every participant their own calendar, link and QR code, with a leaderboard of who has filled the most dates. A large club or school groups them by grade or age with a leaderboard for each group and one team total. And a single cause that wants a longer runway can open a whole year of dates, 365 squares that fill over months as supporters pick the dates that mean something to them.

Fill-the-calendar questions
What is a fill-the-calendar fundraiser?
A calendar fundraiser where the goal is every date claimed. Each day of the month is a gift equal to its date, $1 on the 1st up to $31 on the 31st, and supporters claim dates until the calendar is full. A filled 31-day calendar is $496.
How do you fill the calendar faster?
Share one link by text first. On the real calendars in our case studies the first gift came within two hours of the first text, and the round dates and the last week went first. When ten or fewer dates are left, the calendar offers a supporter the whole rest of the month in one tap.
What happens when the calendar is full?
On a single calendar the page shows every name and note and stops taking gifts. On a team calendar every participant has their own calendar to fill, so the team keeps going until every calendar is full. A year-long calendar has 365 dates to fill.
Can supporters pick more than one date?
Yes. A supporter can claim as many open dates as they like in one checkout, and near the end one tap selects every date that is left.
What does it cost?
Building and running a calendar is free. Donors pay a small service fee at checkout, shown before they pay, and your organization keeps 100% of calendar dollars.
