Epoch Time Converter

What Is Epoch Time?

Epoch time — also called Unix time or POSIX time — is a system for tracking time as a single, continuously increasing number. It counts the total number of seconds that have elapsed since the Unix epoch: midnight on January 1, 1970, UTC.

Because epoch time is timezone-independent, it is the standard way computers, servers, databases, and APIs store and exchange timestamps. When you see a number like 1700000000 in a log file or API response, that is an epoch timestamp representing a specific moment in time — the same moment everywhere on Earth.

How to Use the Epoch Time Converter

1. 1The live counter at the top shows the current Unix timestamp updating every second.
2. 2To convert epoch to date: click the "Epoch → Date" tab, paste your timestamp, and click Convert.
3. 3The tool auto-detects seconds vs. milliseconds — both formats work.
4. 4To convert date to epoch: click "Date → Epoch", pick a date and time, and click Convert.
5. 5Results show UTC, your local time, and ISO 8601 format.
6. 6Click "Use current" to instantly load the live timestamp into the converter.
