Unix Timestamp Converter
Convert Unix epoch timestamps between seconds, milliseconds and human-readable dates directly in your browser.
What is a Unix timestamp?
A Unix timestamp counts the number of seconds (or milliseconds) since January 1, 1970, 00:00:00 UTC, known as the Unix epoch. It is a compact way to store a date and time without relying on a specific calendar format.
How to use this tool
Enter a timestamp and choose its unit to see the matching UTC and local date and time, or enter a date and time to get the equivalent Unix seconds and milliseconds. Use Use Current Time to fill in the current timestamp instantly.
Why developers use Unix timestamps
Unix timestamps are common in APIs, server logs, and databases because they are unambiguous, compact, and independent of time zone or locale formatting.

Switch the unit selector to milliseconds; a millisecond timestamp is simply the seconds value multiplied by 1000.
Does the converter use my local time zone?
The result shows both the UTC (ISO 8601) value and the equivalent date and time in your browser's local time zone.
Why is this useful for developers?
Unix timestamps are widely used in APIs, logs and databases because they are compact, unambiguous and independent of time zone or calendar formatting.
