How Many Days Old Is a 3-Year-Old?

Someone who has just turned 3 has lived 1,095 or 1,096 days. The exact number depends on how many February 29ths fell in those years.

How to work out 3 years in days

Multiply the years by 365, then add one day for every February 29 between the birth date and the 3rd birthday. Leap years come every four years, except century years not divisible by 400, so a 3-year span covers 0 or 1 of them.
