Unix timestamp converter
Paste one or more Unix timestamps and see them as dates, or type a date and get the timestamp. Every line is converted separately, so you can paste a whole column from a log file or database at once.
How it works

Paste your code
Paste the code in the left box or open a file. No code to hand? Click Example.
-
Instant result
The result appears as you type. If there is an error, you see the line and character.

What is a Unix timestamp?
A Unix timestamp (or epoch time) is the number of seconds since 1 January 1970 at 00:00 UTC. For example, 1790000000 is Monday 21 September 2026 at 14:13 UTC. Computers use it because it is a single number, without time zones or daylight saving time. JavaScript and Java count in milliseconds (13 digits), most other systems in seconds (10 digits). With Automatic the tool tells them apart by size; microseconds and nanoseconds are recognised too.
Which dates are recognised?
2026-09-27,2026-09-27 14:30or2026-09-27T14:30:00Z(ISO 8601)27-09-2026or27-09-2026 14:30(day first)- English formats such as
Sun, 27 Sep 2026 12:00:00 GMT
A date without a time zone is read in the chosen zone: My time zone (your device's, including daylight saving time) or UTC. If the date includes a zone, such as Z or +02:00, that one is used.
The year 2038 problem
Older systems store the timestamp as a 32-bit number. That overflows on 19 January 2038 at 03:14:07 UTC (timestamp 2147483647). Modern systems use 64 bits and are not affected.
