Unix timestamp converter
Convert a Unix timestamp (seconds since January 1, 1970) into a readable date, and vice versa, directly in your browser — handy for debugging a timestamp found in a database or an API response.

How it works
A Unix timestamp is simply a counter of seconds elapsed since January 1, 1970 at midnight UTC (the "epoch"). It's the format most databases, APIs and server logs use internally to store a date, because it's compact and easy to compare or sort. The problem: a raw timestamp like 1753876200 isn't readable by a human. This tool converts back and forth between this number and a readable ISO 8601 date, which is useful for debugging a value found in an SQL query, a JSON API payload, or a log file.
Why does my timestamp seem "off" by a few hours?
This tool always displays and interprets dates in UTC (universal time), without applying a local time zone. If you're comparing the result to the time shown on your computer, remember to account for your time zone offset — or use this site's dedicated "Time zone converter" tool for that offset.
Does the field accept dates before 1970?
Yes, the calendar calculation handles both negative timestamps (dates before January 1, 1970) and dates very far in the future, thanks to a Gregorian calendar algorithm valid across the entire range representable by a signed 64-bit integer.
100% local processing: the conversion happens directly in your browser via WebAssembly, without any call to an external server.
