Harold Ramis Day is observed in Chicago every February 2, coinciding with Groundhog Day. This day honors Harold Ramis, a Chicago-born actor and filmmaker renowned for his role as Egon Spengler in the Ghostbusters films and for directing Groundhog Day. The city officially designated this day in 2024, nearly a decade after Ramis's death. Celebrations typically take place at Harry Caray’s Tavern on Navy Pier, where items related to Ramis's work, such as Egon Spengler’s glasses and jumpsuit, are displayed. The inaugural Harold Ramis Day featured a reunion of the cast from Groundhog Day, marking a significant moment for many who had not seen each other in decades. Initially focused on Groundhog Day, the celebrations have expanded to include tributes to Ramis's other notable works, such as National Lampoon’s Animal House.
