About this tool
Choose a date and time using the local date-time input. The tool displays Unix seconds, a UTC ISO string and the relative distance from now.
The input is interpreted in the browser timezone. It does not accept an epoch number for reverse conversion, expose a milliseconds input, or provide a source-timezone selector. Daylight-saving ambiguities follow browser Date behavior.
Frequently asked questions
Can I paste a Unix timestamp to decode it?
No. This version converts a selected local date and time to Unix seconds and ISO output only.
