The most straightforward method involves a simple subtraction:
- Identify the current year (or any reference year).
- Subtract the person's age from that year.
This gives you an approximate birth year. However, for precision, consider the individual's birth date within the reference year.
Accounting for Birth Date
To refine your birth year calculation, consider these rules:
- If the reference date is before the person's birthday in that year, subtract one year from the initial result.
- If the reference date is after their birthday, the initial result is accurate.
For example, if today is October 1, 2024, and someone is 30 years old but their birthday is December 25th, their birth year is 1993 (2024 - 30 - 1). If their birthday has already passed in 2024, their birth year is simply 1994 (2024 - 30).
Alternative Method: Calculate Based on Age Range
Another method is to simply select a 'check age range' option, in which if their birthday has passed, they will be 30, but if their birthday has not passed, they will be 29. We would then calculate two different years, 1994 and 1995, and be able to tell the user there is a year of uncertainty.
