Epoch Converter
Convert Unix epoch timestamps to human-readable dates and back again. Auto-detects seconds, milliseconds, and microseconds, and shows the result in UTC, your local time, and any timezone you pick.

About the Epoch Converter
Unix time (also called epoch time or POSIX time) is the number of seconds elapsed since 00:00:00 UTC on 1 January 1970, not counting leap seconds. It is the standard way computers store and exchange points in time, because a single integer is unambiguous across timezones and locales.
Logs, databases, JWTs, and APIs constantly return these raw numbers, and reading them by eye is impractical. This converter turns them into dates you can actually reason about — and converts the other way when you need a timestamp for a query or test fixture.
How to use it
- 1Paste a Unix timestamp to instantly see the matching date in UTC and your local zone.
- 2Or pick a date and time to get its epoch value in seconds and milliseconds.
- 3Use the timezone selector to convert the result into any region.
Features
- Bidirectional: timestamp → date and date → timestamp
- Auto-detects seconds, milliseconds and microseconds
- Shows UTC, local time, ISO 8601 and relative ("3 hours ago") output
- Live "current Unix time" clock you can copy with one click
Frequently asked questions
What is a Unix timestamp?
It is the number of seconds since January 1, 1970 00:00:00 UTC (the Unix epoch). A 10-digit value is typically seconds, 13 digits is milliseconds, and 16 digits is microseconds.
How do I convert milliseconds?
Just paste the value — the converter auto-detects whether your number is in seconds, milliseconds, or microseconds and converts accordingly.
Does it handle timezones?
Yes. Results are shown in UTC and your local timezone, and you can select any IANA timezone to convert into.
What about the year 2038 problem?
That affects systems storing time in a signed 32-bit integer, which overflows in 2038. This tool uses 64-bit JavaScript numbers, so it handles dates far beyond that.
