Epoch converts Unix timestamps into readable dates and back again. Paste a timestamp — in seconds or milliseconds, it figures out which — and see it in your local time, in UTC, as an ISO 8601 string, and as a relative time like "3 hours ago." Or pick a date to get its timestamp. Everything runs in your browser; nothing is uploaded.

A Unix timestamp counts the seconds (or milliseconds) since 1 January 1970 UTC, the "epoch." Values of about 13 digits or more are read as milliseconds, shorter ones as seconds. Local times use your device's time-zone setting; UTC and ISO strings are absolute. Everything runs on your device; nothing is uploaded.
