The best way to see whether a year is leap year or not is to look at the last 2 digits of an year. That's the divisibility test of 4. ...

For anyone who is curious as to why there isn't a leap year on the year 2100 or 2200, 2300, 2500, there's an explanation. The rules for when a leap year happens actually has 2 extra conditions that aren't often mentioned because they are almost never used. The first rule most of us know is that a leap year occurs every 4 years, which adds an extra day to the February calendar.However, this rule isn't applied to any year that's divisible by 100. For example, 2100 will not be a leap year because 2100 is equally divisible over 100.The second condition is that the previous condition is overruled if the year is also divisible by 400. Which is why the year 2400 will still be a leap year, even if it's divisible by 100, because of the fact that it's divisible by 400. I believe the reasoning for this is because a year isn't actually exactly 365.25 days, it's more like 365.24255 days, so they need to compensate for the 42 minutes that are gained every leap year somehow. Again, I'm no expert or mathematician, but I'm sure someone more qualified can give an explanation as to why. ...
