Epoch Converter
Convert unix timestamps to and from human-readable dates in any time zone.
Input
What it does
Converts between unix timestamps (seconds or milliseconds) and human-readable dates. Paste a timestamp to see it as ISO 8601, local time, and relative time, or paste a date string to get its unix timestamp. Detects seconds vs milliseconds automatically.
How to use it
Paste a timestamp like 1754521200 or a date like 2026-08-06T21:00:00Z into the input. Pick a time zone to see the conversion there. Every value has its own copy button, and the URL updates so you can share exactly what you see.
Why this one
The popular epoch converter sites bury the answer under ads and cookie banners. This one is instant, works offline, never sends your input anywhere, and has no usage limits.
FAQ
- Does it handle milliseconds?
- Yes. Values of 13+ digits are treated as milliseconds, shorter ones as seconds. Both conversions are always shown.
- Is my input sent to a server?
- No. The conversion runs entirely in your browser, and the page works offline after first load.
- What date formats can I paste?
- Unix seconds, unix milliseconds, ISO 8601, RFC 2822, and anything else your browser can parse natively.
