Is every 400 years a leap year?
All years divisible by 4 are leap years. Exceptions occur at the end of century: if the year is divisible by 100, it is not a leap year, unless it is also divisible by 400. Thus, 1700, 1800, 1900 were not leap years, but 1600 and 2000 were leap years.All years divisible by 4 are leap years.
