# Age calculator

Canonical page: https://nepocore.com/tools/age/

Calculate calendar age on a chosen date, including years, months and days. Also see the elapsed number of days and full weeks.

## How to use it

1. Enter the numbers, dates or units you want to compare.
2. Choose the calculation options and calculate.
3. Review the result together with the assumptions shown.

## Example

Check your age on an application deadline rather than only on today’s date.

## Limits and checks

Month-end anniversaries are clamped to the last valid day of the month. The comparison date must not precede the birth date.

## Access and processing

Free to use without an account. Interactive processing requires JavaScript in a modern browser. Input is processed in the browser rather than sent to a processing server. Optional browser storage is not a synchronized account.
