Just adding a day doesn’t quite tweak the calendar; it’s still off by a few minutes. So, “leap years occur in years divisible by four, except for those divisible by 100 and not divisible by 400. Confusing enough for you? In effect, that means that 97 out of every 400 years are leap years, including the century years 1600 and 2000 but NOT 1700, 1800 and 1900.”*
