To help you make the most of it, we've rounded up all the special events that will celebrate the once-every-four-years occasion on Saturday, February 29 (though there are also lots of other events on Leap Day!), from the Boylston/Harvard Leap Day 2020 Pub Crawl Past Event Like List to Lady Yum’s Extra Day To Be Extra Past Event Like List .
