# Baby age calculator

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

Show a child’s age in calendar months, weeks and days. This browser tool shows the inputs, assumptions and resulting output so you can use it for a specific everyday task.

## How to use it

1. Enter your own values or choose a supported file.
2. Adjust the options and run the tool.
3. Review the result, then copy, export or save it when available.

## Example

Compare a birth date with a selected reference date to see age in months and weeks.

## Limits and checks

This is calendar arithmetic, not a developmental assessment. Corrected age for prematurity is not automatically assumed.

## 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.
