It may be winter in Pittsburgh, but without a Leap Day every four years, it could very well be summer right now.

According to NASA, the earth takes about 365.2422 days to fully revolve around the sun. Except there’s one problem; calendars measure a year as a whole number — 365 days. The remaining fraction of a day (NASA estimates it’s about 6 hours) adds up to an extra 24 hours every four years. That time is added to February every Leap Year as Feb. 29 to even things out.

Events like seasons, equinoxes and solstices would slowly lose their designated date if that extra time wasn’t accounted for. They would move later and later into the year, NASA explains.

So, what will you do with your extra day this year? Here are some ideas on how to spend it around town.

1. Take a Leap: Singles Mingle

The Woods House | 6:30-8:30 p.m.

Head to the Woods House Historic Pub for snacks, games and a complimentary beverage. Oh, and mingling. Who knows, you could just end up with the elusive Leap Day anniversary.

2. Sadie Hawkins Dance

Bottlerocket Social Hall | Doors open: 5 p.m., Start: 8 p.m.

7. Leap “Frog” Day with Princess Tiana

8. Eat for Free

Eat’n Park, Hello Bistro, The Porch, City Works | All day

If you have the ultra-rare Leap Day birthday, you’ve just earned yourself a free meal (or a few, at that!). Leaplings will get a free entrée at Eat’n Park, a free meal at Hello Bistro — think burgers, wraps, grain bowls, etc. — and a scratch-made pizza at The Porch. Those offers are dine-in only. Meanwhile, Leaplings can also expect a free entrée at City Works.

Admission: Must show a valid ID with a birthday of Feb. 29.
