We know that (1) if the whole hundred years, can be divisible by 400, is a leap year, (2) if not the whole hundred years, can be divisible by 4, is also a leap. Every 400 years, there are 97 leap year. In view of this, the procedure can be designed as follows: The first step is to determine whether the year is divisible by 400 and, if possible, leap years. For example, 1600, 2000, and 2400 are leap years. The second step is to determine whether the
