# Birthday countdown

Canonical page: https://nepocore.com/tools/birthday-countdown/

Count down to a birthday or a chosen event and make a shareable card. 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

Choose a birthday month and day to see the next occurrence and a live countdown.

## Limits and checks

The countdown uses the selected local date and clock. A February 29 birthday follows the explicitly selected non-leap-year policy.

## 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.
