Usage of this Site

This site can be used in a number of different ways.


This is this site's raison d'ĂȘtre—to give easy access to timestamp translations directly from a browser's address bar.

Timestamp URIs

The easiest way to get information on a particular Unix time is to enter it directly into your browser's address bar, like so:

This will bring up information about Unix time 123456789.

Date and Time URIs

If you want to go in the opposite direction and get a timestamp for a particular date and time, you can do this by building a URL with the year, month and date, followed by optional hour, minute and second values.

For example, to get the Unix time for the 31st March, 1978, use the following URI:

For 3:45:22 PM on that day, just add the hour (in 24-hour time), the minute and the number of seconds to the URI:

Descriptive URIs

You can also request a description of any date and time, and using the magic of the python-dateutil module, the site will do it's best to try and figure what you're on about.

Unix Timestamps as a Service (UTaaS)

By setting the Accept header of your request to application/json, you can get the same information in JSON format.

$ curl -L -H "Accept: application/json"
  "datetime": "Fri, 31 Mar 1978 00:00:00 GMT", 
  "timestamp": 260150400
