Unix Timestamp Converter

Convert a Unix timestamp to a human-readable date, or a date to its timestamp. Auto-detects seconds, milliseconds, microseconds or nanoseconds and shows UTC, your zone and any zone, with a live epoch clock. Calculates in your browser.

Timestamp → date

How it works

A Unix timestamp counts the seconds elapsed since the Unix epoch, midnight UTC on 1 January 1970. It's the same number everywhere on Earth, independent of time zone, which makes it the standard way computers store an instant in time.

Enter a timestamp to see it as a human-readable date, or pick a date and time to get its timestamp. Many systems use milliseconds, microseconds or nanoseconds instead of seconds; auto-detect picks the right scale from the size of the number, or you can set it yourself.

The same instant is shown in UTC, your own zone and any zone you choose. Everything is calculated locally in your browser, nothing is sent anywhere.

What this does

A Unix timestamp converter turns an epoch timestamp into a human-readable date, or a date into its timestamp, auto-detecting seconds, milliseconds, microseconds, or nanoseconds.

How to use it

  1. Paste a timestamp or enter a date.
  2. Let it auto-detect the units, or set them.
  3. Read the date in UTC, your zone, and any zone.
  4. Watch the live epoch clock.

How it works

Unix time counts seconds from the epoch, midnight UTC on 1 January 1970. Because it is tied to UTC, the same timestamp means the same instant everywhere in the world.

timestamp = seconds since 1 Jan 1970 UTC

Example

The timestamp 1000000000 is 9 September 2001, 01:46:40 UTC.

Frequently asked questions

What is a Unix timestamp?

It is the number of seconds that have passed since the Unix epoch, midnight UTC on 1 January 1970. Because it is tied to UTC, the same timestamp means the same instant anywhere in the world.

Seconds, milliseconds or something else?

Plain Unix time is in seconds (a 10-digit number today), but many systems use milliseconds (13 digits), microseconds (16) or nanoseconds (19). Auto-detect chooses the scale from the size of the number, or you can set the units yourself.

Which time zone is used?

Timestamps are converted and shown in UTC, your device’s zone, and any zone you select. When you enter a date to convert into a timestamp, it is read as the wall-clock time in the zone you choose, with the correct daylight-saving offset.

Is my data stored?

No. Everything is calculated locally in your browser and nothing is sent anywhere.
