About the year 2009
2009 began on a Thursday and was not a leap year, with 365 days. 6,434 days have passed since 1 January 2009.
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 16 to 17 on the birthday itself.
