Last time, the "sweet spot" seemed to be around 5 weeks, which would place us somewhere around Flag Day, if looking for a national holiday theme.
Today we are already 5th on the all-time best list of money the campaign has raised in a single day, with at least 5 hours to go:

So, my vote is for somewhere around Tuesday, June 14th. It gives everybody time to regroup and make proper preparations like sites, videos, banners etc. It also allows time for gearing up teams for mass messaging.
5 weeks. Flag Day. June 5th is too soon, but nobody is stopping anyone from donating!
