About the year 1998
1998 began on a Thursday and was not a leap year, with 365 days. 10,452 days have passed since 1 January 1998.
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 27 to 28 on the birthday itself.
