About the year 2005
2005 began on a Saturday and was not a leap year, with 365 days. 7,895 days have passed since 1 January 2005.
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 20 to 21 on the birthday itself.
