A: You can use any reference year (not just the current year) to calculate birth years for historical figures.

Q3: How accurate is this calculation?
A: It's accurate to within ±1 year unless you know whether the person has had their birthday in the reference year.

Q4: Can I use this for future years?
A: Yes, you can input future years to calculate what someone's birth year would be if they were a certain age in that future year.

Q5: What about people born BCE (Before Common Era)?
A: This calculator uses the Common Era (CE) system. For BCE dates, you would need to adjust the calculation accordingly.
