How to calculate birth year from age 105
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 - 105 - 1 = 1919
If someone has had their birthday this year, then the formula is
{Current Year} - {Age} = {Birth Year}
2025 - 105 = 1920
