Understanding start and end dates
The start and end dates that you enter don’t actually affect the functionality of your campaign at all; they’re purely for descriptive purposes. People can still record pledges on your campaign after the end date.
The end date is optional, but it’s good for creating a sense of urgency, encouraging people to get on and record their pledges now.
People usually use the dates to clarify when the campaign to raise pledges is running from, i.e. from the first to last day that you are actively promoting it. However, supporters will still be carrying out their pledges for up to two months beyond this date, so we always recommend Pro or Plus users keep their subscription active for at least three months, allowing them to view the full data as it comes in.
