It only comes around once every four years, so we're determined to make Leap Year count today. And, judging by the online buzz, we're not the only ones.
We've found five ways to mark the occasion and we want to make it to 10, so let us know what you're doing to celebrate. Tell us in the comments or tweet us @GuardianUS and we'll update the list throughout the day.
Here are our plans so far:
Drink
Slate published a recipe for an odd gin-based Leap Day cocktail that should probably be mandatory for anyone working an extra 24 hours this year. Bottoms up!
Remember Ja
Wish Ja Rule a happy 9th birthday on Twitter. You can't do it in person, though, as he's doing time for gun posession. Still, he managed to release his seventh album from behind bars yesterday. Happy birthday, Ja.
Shop
Retailers would love you to spend your extra 24 hours spending money, and discounts are flooding the web. Everyone from Trump Hotels to McDonalds is offering something special today. Time Magazine has put the best deals together here.
Save a frog
The Amphibian Ark is taking advantage of the "leap" in Leap Day to sponsor Leaping Ahead of Extinction: a campaign that encourages people to "visit participating institutions on or around Leap Day 2012, to learn more about their amphibian conservation programs, and what they are doing in response to the global amphibian crisis". Find a participating institution in your area here.
... Or eat one
Not fond of frogs? Well how about "frog legs for Leap Day" a recipe the Boston Herald published today.
We're on a mission to add five more Leap Day activities to this list. Contribute below the line or tweet us.
