Paste a timestamp and see it as a date in UTC, your time zone and ISO 8601, plus how long ago it was. The unit
(seconds, milliseconds, microseconds or nanoseconds) is detected from the number's size, or you can choose it.
Paste a date such as 2026-10-22T12:00:00Z to get the timestamp instead.
Good to know
What is a Unix timestamp?
The number of seconds since 1 January 1970 at midnight UTC. Many systems count milliseconds instead, which is why the unit matters.
How is the unit detected?
By the number of digits: today's time is about 10 digits in seconds, 13 in milliseconds, 16 in microseconds and 19 in nanoseconds. Choose the unit yourself for dates far in the past or future.
Which time zones can I see?
Yours, detected from your browser, and a list of common zones. The conversion uses your browser's own time zone data.
