Epoch to Date Converter
Convert an epoch or Unix timestamp to a readable date and time. Paste seconds or milliseconds and get UTC and local time instantly.
Part of the free Unix Timestamp Converter. Runs in your browser — nothing is uploaded.
Epoch to Date Converter
Epoch time counts seconds since 1 January 1970 UTC. Logs, databases and APIs love it, humans do not. Paste a number and the converter shows the matching date in UTC and in your local timezone.
Worked example: Seconds since the epoch to a date
Epoch (seconds)
1700000000
UTC date
2023-11-14 22:13:20 UTC 2023-11-14T22:13:20.000Z
Practical tip
Count the digits. 10 digits is seconds and 13 digits is milliseconds. Mixing them up is the number one cause of dates in 1970 or the year 55000.
How to use this Unix Timestamp
- 1Use the live tool above — it runs entirely in your browser and never uploads your data.
- 2Paste the sample from the worked example, or use your own input.
- 3Copy the result, then adapt the same steps in your editor, script, or pipeline.
Epoch to Date Converter FAQs
What is the Unix epoch?
The epoch is 00:00:00 UTC on 1 January 1970. A Unix timestamp is the number of seconds that have passed since then, ignoring leap seconds.
Is epoch time affected by timezone?
No. A timestamp is the same instant everywhere. Timezones only affect how that instant is displayed as a local date.
