7-Eleven, Inc. has choreographed a super-cool celebration to mark its 86th birthday Thursday, July 11 (that’s 7/11, btw), better known by fans of its popular frozen drink as Free Slurpee® Day. Big things are in store and online for the festivities:

• Free small Slurpee drinks — That’s a full 12 ounces, almost double the previous years’ 7.11-ounce size. Offered from 11 a.m. to 7 p.m. local time on Thursday, July 11, at participating 7-Eleven® stores in the U.S. and Canada
