About This Tool

A Unix timestamp is the number of seconds that have elapsed since 1 January 1970 at 00:00 UTC, a reference point known as the epoch. This converter turns that integer into a readable date and time, and turns a human date back into a timestamp, which is the format most databases, logs, and APIs use internally.

Because the value is counted in UTC, the same timestamp shows as different local clock times around the world, so the tool lets you see both the UTC reading and your local one. It also handles millisecond timestamps, which many systems use for finer resolution, by detecting the extra digits and scaling accordingly.

A well-known wrinkle is the year 2038 problem: systems that store the timestamp in a signed 32-bit integer will overflow early that year, which is why modern systems use 64-bit values. When converting, it also matters whether a value is in seconds or milliseconds, since misreading the scale shifts the date by decades.

How to Use It

  1. Paste a Unix timestamp to convert it to a readable date, or enter a date to get the timestamp.
  2. Choose whether the value is in seconds or milliseconds.
  3. Read the result in both UTC and your local time zone.
