4 years = 1460 days. Finding this answer is simple, but it has a twist. We know that there are 365 days in a year, so to find out how many days are in four years, we would multiply 365 times 4 to get our answer (365 * 4 = 1460).
To calculate the number of days between two dates, you need to subtract the start date from the end date.
The use of the 360-day year for accounting and administration lasted until the Old Babylonian period. The same number was used in cuneiform literature for astronomical calculations even later, throughout the first millennium BCE.v
In the Julian calendar, the average (mean) length of a year is 365.25 days. In a non-leap year, there are 365 days, in a leap year there are 366 days. A leap year occurs every fourth year during which a leap day is intercalated into the month of February. The name “Leap Day” is applied to the added day.
