Leap year Memes

Oh, the sweet false security of unit tests on leap day! You're all confident when the boss messages you because you actually wrote tests for once. Then February 29th rolls around and your date handling logic implodes spectacularly. Nothing says "I'm a professional developer" quite like your app crashing every four years because you hardcoded month lengths or forgot leap year logic exists. The calendar: nature's way of trolling programmers since the beginning of time.
