How many days are there in 7 years?

Answer 1

There are 3 different answers because of the leap years. this is 7 years with 2 leap years: If the beginning year is a leap year, when the leap year is next year, or the leap year is two years after the beginning year, there will be two leap years in the seven year period, and so the number of days will be 2557. If the beginning year isn't in any of the above catergories, there will only be 2556 days, because of only one leap year.

If the beginning year is 3 years before a year that is a multiple of 100, but not a multiple of 400, there will be no leap years. For example, the 7 year period beginning in 2097 has no leap years because 2100 is not a leap year. In that case there will be 365 * 7 = 2555 days.
