About
To calculate school age, subtract the child's birth year from the current year, then adjust based on whether the child has had their birthday this year. For example, if the current year is 2024 and the child was born in 2010, the basic calculation is 2024 - 2010 = 14. If the child has already had their birthday this year, their school age is 14; if not, it is 13.
