Age & Date Calculator
Calculate age, date differences, and more
What is this tool?
Calculates exact age in years, months, and days from a birth date, or the number of days between any two dates -- more precise than the rough mental math of subtracting years, which doesn't account for whether the birthday has actually happened yet this year.
How to use it
Enter a birth date (or two dates for a general date difference), and the calculated age or interval appears immediately.
This is also useful for far more than birthdays -- counting days until a deadline, the exact duration of an event, or how many days pregnant someone is all work the same way, just by entering the relevant two dates instead of a birth date and today.
