EA Giving Tuesday is an initiative to direct matching funds from Facebook's Giving Tuesday program to EA-aligned organizations.
Giving Tuesday is a holiday celebrated on the first Tuesday after American Thanksgiving (either the last week of November or first week of December). Its organizers (GivingTuesday 2021) describe it as
a global generosity movement unleashing the power of people and organizations to transform their communities and the world. GivingTuesday was created in 2012 as a simple idea: a day that encourages people to do good. Since then, it has grown into a year-round global movement that inspires hundreds of millions of people to give, collaborate, and celebrate generosity.
