If you’re a Mean Girls fan, then you know what day it is. It’s Oct. 3, the same day Aaron Samuels turned to Cady Heron in math class and asked for the date. The day has since been dubbed Mean Girls Day, and some of the cast members are commemorating the event on social media.

Lindsay Lohan (Cady), Jonathan Bennett (Aaron), and Daniel Franzese (Damian) all tweeted in celebration. “It’s October 3rd FYI,” Lohan wrote on Instagram, while Bennett tweeted that his “phone is blowing up.”

Franzese, meanwhile, has been the busiest of the bunch. In addition to posting a “then and now-ish” photo on Instagram, he also recorded a special message for the ABC Family Twitter feed, finishing with his famous one-liner: “You go, Glen Coco!” Mean Girls is set to air on the network Saturday at 6:45 p.m. ET.

Tina Fey (writer, Ms. Norbury), Rachel McAdams (Regina), Amanda Seyfried (Karen), Lacey Chabert (Gretchen), and Lizzy Caplan (Janis) haven’t posted anything yet, but the day is young. To learn more about Mean Girls Day, click here. Otherwise, test your knowledge of the film with EW’s quote quiz.
