Yes, it's Leap Year day, or whatever it's called.  Those folks who were born on Feb. 29th get to have a real birthday party this year. 
You can read about leap year and other "timely" matters on the rather wonderful website of  the National Institute of Standards and Technology Time and Frequency Division, an operating unit of the Physics Laboratory of the National Institute of Standards and Technology (NIST), an agency of the U.S. Department of Commerce that is  located in Boulder, Colorado at the NIST Boulder Laboratories.  While you're there you can check out their online exhibits about timekeeping and calendars through the ages, and you can also set your watch and be sure it's the right time!
