How to calculate birth year from age 15

For calculating the year someone was born base on their age, the formula depends on whether they have already had their birthday this year.

If someone has not yet had their birthday this year, then the formula is

{Current Year} - {Age} - 1 = {Birth Year}

2025 - 15 - 1 = 2009

If someone has had their birthday this year, then the formula is

{Current Year} - {Age} = {Birth Year}

2025 - 15 = 2010
