Birth Year Calculation Formula
Birth Year = Current Year – Age
If your birthday hasn’t occurred yet this year:
Birth Year = Current Year – Age – 1
Where:
• Current Year = The present calendar year
• Age = Your current age in whole years
• Birthday Adjustment = Subtract 1 if birthday hasn’t passed

Example 2: Birthday hasn’t passed
Current Year: 2024
Age: 30
Birthday: Still coming in 2024
