I noticed that my (relatively inexpensive) digital watch says that it's March 1, not February 29. The dates on computer systems, cell phones, and most newer and more expensive electronic devices should update automatically, but don't forget to check on other small appliances and electronics and such, as well as any clocks or watches with day/date functions. It might save you from accidentally post-dating a check or missing a meeting.

Enjoy the day, and remember that it's rarer than most other holidays. I've seen 40 Christmases and 40 Independence Days, but this is only my 11th Leap Day. (I'm shooting for 25 of them, by the way.)
