About the year 2008
2008 began on a Tuesday and was a leap year, with 366 days and a 29 February. 6,800 days have passed since 1 January 2008.
Age in whole years only counts the birthday that has already happened. That is why two people born in the same year can be different ages today — and why the answer flips from 17 to 18 on the birthday itself.
