About the year 1978
1978 began on a Sunday and was not a leap year, with 365 days. 17,757 days have passed since 1 January 1978.
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 47 to 48 on the birthday itself.
