Unix Timestamp Converter
Convert Unix epoch timestamps to human-readable dates in IST, UTC and your local zone, and convert dates back to timestamps.
What is the Unix Timestamp Converter?
Unix time is how computers commonly store moments in time — a single number of seconds since 1 January 1970 UTC.
How does it work?
Timestamps are read as seconds, milliseconds or microseconds depending on their length and formatted with the Intl API. Dates are converted using the chosen time zone’s offset for that date.
Formula
Date = Epoch (1970-01-01T00:00:00Z) + timestamp seconds
Example
1700000000 is 14 November 2023, 22:13:20 UTC (15 November, 03:43:20 IST).
Frequently asked questions
What is a Unix timestamp?
The number of seconds since 00:00:00 UTC on 1 January 1970 (the Unix epoch), ignoring leap seconds. It is the same everywhere in the world at a given moment.
Seconds or milliseconds?
Unix tools and most APIs use seconds (10 digits today). JavaScript and Java use milliseconds (13 digits). The converter detects the unit from the number of digits.
