FAQ
Does the age calculator account for leap years?
Yes, the calculator uses JavaScript Date objects which automatically handle leap years (February 29th), ensuring accurate total day counts.
Why might the exact age and total days seem inconsistent?
Because months have different lengths (28-31 days), the exact age is calculated step by step through years, months, and days, while total days are calculated directly by calendar days. Both methods are correct but use different logic.
How is the next birthday countdown calculated?
The system calculates the number of days from today to your next birthday. If today is your birthday, a special message is displayed. If this year's birthday has already passed, it counts down to next year's birthday.
