Calendar moment ↔ Unix epoch — without the time-zone surprise.
seconds since the Unix epoch
Times are interpreted in your local zone. The Unix value below is the same instant, no zone attached.
Unix time has no time zone — it counts the same seconds everywhere on Earth. Inputs above ~10¹² are read as milliseconds, above ~10¹⁵ as microseconds.

常见问题
Quick answers.
›Does it accept milliseconds?
Yes. Numbers ≥ 10¹² are treated as milliseconds; smaller numbers as seconds.
›What timezone is shown?
Both UTC and your local browser timezone are displayed side by side, plus an ISO 8601 formatted string.
›What's the Year 2038 problem?
32-bit signed integer timestamps overflow on 19 January 2038 03:14:07 UTC. Modern systems use 64-bit timestamps, which are safe for billions of years.
›Why does my timestamp look weird?
Most likely you've got seconds/milliseconds mixed up. A 10-digit timestamp is seconds; 13 digits is milliseconds.
›Is the converter free?
Yes — fully free, no signup, runs in your browser.
