How to convert a Unix timestamp
Paste a Unix timestamp to see it as a date in your time zone, in UTC and in ISO 8601 format. Seconds, milliseconds, microseconds and nanoseconds are detected from the number of digits, or you can pick the unit. To go the other way, type a date such as 2026-10-14 12:00 and copy the timestamp in seconds or milliseconds.
FAQ

The number of seconds since January 1, 1970 at 00:00:00 UTC, called the Unix epoch. It is the same everywhere in the world, which makes it a common way to store dates in databases and APIs.
Is my timestamp in seconds or milliseconds?
Present-day timestamps have 10 digits in seconds and 13 in milliseconds. JavaScript’s Date.now() returns milliseconds, while most Unix tools and PHP’s time() return seconds. The converter detects the unit from the number of digits.

Systems that store Unix time as a signed 32-bit integer overflow on January 19, 2038 at 03:14:07 UTC, the timestamp 2147483647. Modern systems use 64-bit values, which last for billions of years.
