Gotta love a good Leap Day!
I remember one of the first bits of code I wrote during my first year of computer science was a data validation and we used this canonical bit of pseudocode
if (year modulo 4 is 0) and ((year modulo 100 is not 0) or (year modulo 400 is 0)) then leap else no_leap
Hope you get to put your extra day of the year to good use.
I'm going to the gym tonight for an extra little workout. Maybe take the family out for some dinner.
