Question 1

How accurate is the age calculation?

Accepted Answer

The calculation is precise to the day, accounting for leap years, different month lengths, and whether your birthday has occurred yet in the current year.

Question 2

Can I calculate age for a future date?

Accepted Answer

No. The calculator only accepts past dates. For future date calculations, use a date difference calculator.

Question 3

What does "total hours" include?

Accepted Answer

Total hours is calculated from midnight of your birth date to right now, based on total days × 24. It does not account for your exact birth time.

Question 4

How is the next birthday countdown calculated?

Accepted Answer

It finds the next occurrence of your birth month and day — either this year or next year if your birthday has already passed — and counts the days remaining.
