Frequently Asked Questions
How is age calculated?+
Age is calculated by finding the difference between your date of birth and the reference date (today or a date you choose). The result is broken down into years, months, and days, accounting for varying month lengths and leap years.
Can I calculate age on a future date?+
Yes. Enable the 'Calculate age as of a specific date' option and pick any future date. The calculator will show how old you will be on that date.
Why does the calculator show months and days separately?+
Showing age as years, months, and days gives a more precise result than years alone. For example, someone born on March 15, 1990 might be 36 years, 3 months, and 26 days old — not just 36.
How is 'days until next birthday' calculated?+
The calculator finds your next birthday (same month and day as your birth date in the current or next calendar year) and counts the days from the reference date to that birthday.
