Epoch ↔ human time
A Unix timestamp is the number of seconds since 1 Jan 1970 UTC. Paste one to see the date in your timezone, UTC and ISO-8601 — or pick a date to get the timestamp. It auto-detects seconds vs milliseconds.

Frequently asked questions
Common questions about the Unix Timestamp Converter.
Is the timestamp in seconds or milliseconds?
Both are supported. A 10-digit number is interpreted as seconds and a 13-digit number as milliseconds; the tool detects the length so you do not have to divide or multiply by 1000 yourself.
What is the Unix epoch exactly?
It is the count of time since 00:00:00 UTC on 1 January 1970, not counting leap seconds. So timestamp 0 is that moment, and the number grows by one each second.
Does it show the time in my timezone or UTC?
It shows both side by side — the date in your local timezone and the equivalent in UTC — so you can read whichever you need without manual offset math.
Can I convert a human date back into a timestamp?
Yes, it works in both directions: paste a timestamp to get a date, or enter a date and time to get the matching epoch value.
What is the Year 2038 problem?
Systems that store Unix time in a signed 32-bit integer overflow on 19 January 2038, when the second count exceeds 2,147,483,647. Modern 64-bit timestamps are unaffected, and this converter handles dates well beyond 2038.
