Why convert a date to a timestamp?

Databases, caches and APIs expect epoch values, while humans write dates. Type a date above (or “now”) to get the Unix timestamp in seconds and milliseconds.

How it works

The converter parses the date locally with the browser’s engine and prints Unix seconds, Unix milliseconds and the normalized ISO 8601 (UTC) form, so you can double-check the parse did what you meant — time-zone suffixes included.

Frequently asked questions

Is my data uploaded to a server?
No. Everything runs entirely in your browser with JavaScript. Nothing is sent over the network, which makes the tool safe for sensitive data.
Which date formats are accepted?
Anything JavaScript’s Date.parse understands: ISO 8601 (2026-06-11T12:00:00Z), RFC 2822, plain dates like 2026-06-11 — plus the keyword “now” for the current time.
