Question 1

How are leap years handled?

Accepted Answer

We use JavaScript's built-in Date object which correctly handles leap years. February 29th birthdays are accounted for — in non-leap years, the birthday falls on March 1st.

Question 2

Can I calculate the age between two historical dates?

Accepted Answer

Our calculator uses today's date as the end date. For calculating the time between two specific dates, use the years, months, and days approach with your own end date.
