Guide

How Timestamp Converter works

Step 01
Type an epoch timestamp

Paste seconds (10 digits) or milliseconds (13 digits) — we detect and convert either.

Step 02
See all human formats

ISO 8601 (UTC), local time, UTC string, locale format, milliseconds, and timezone offset — all in one row.

Step 03
Copy any format

Per-row copy button. Use the 'Now' banner at the top to grab the current epoch with one click.

FAQ

Frequently asked

How does it distinguish seconds from milliseconds?+

Anything > 1e12 is treated as milliseconds; below that as seconds. Both edge cases (very old dates, very future ones) fall within the seconds range.

Does it handle timezones?+

The Local + Locale rows use your browser's timezone. The ISO 8601 + UTC rows are always in Z / UTC.

Does it work offline?+

Yes — parsing uses the browser's built-in Date object. No network required.
