April 2 is International Pillow Fight Day. Across the globe, communities will gather together to pummel each other with pillows. Wearing pajamas is encouraged.
Philly will celebrate the holiday in Washington Square Park around 3 p.m.
Attendees should remember these rules for a good, clean fight: Soft pillows only, and don't hit people without pillows.
