Question 1

How is exact age calculated?

Accepted Answer

We calculate the difference between your birth date and the current date, accounting for varying month lengths and leap years. The result is broken down into years, months, days, hours, minutes, and seconds.

Question 2

Does this account for leap years?

Accepted Answer

Yes! Our calculator correctly handles leap years (years divisible by 4, except centuries not divisible by 400). February 29 birthdays are handled specially.

Question 3

Why might my age in days differ from other calculators?

Accepted Answer

Some calculators use a fixed 365-day year. We calculate the actual number of days elapsed, including leap days, which gives a more accurate result.

Question 4

How accurate is the seconds calculation?

Accepted Answer

The total seconds are calculated from the exact millisecond difference between your birth date (midnight) and the current time. It updates in real-time.
