How to Use the UNIX Timestamp Converter
A UNIX timestamp is the number of seconds elapsed since January 1, 1970, 00:00:00 UTC. It's widely used in server logs, databases, and API responses to store dates and times as a single number — but a raw number like 1738368000 doesn't tell you the actual date at a glance.
This tool converts in both directions. Enter a timestamp above to see the equivalent local date/time and UTC time instantly. Below, pick any date and time to calculate its UNIX timestamp in seconds.
Use it to figure out when a log entry actually happened, calculate a timestamp for an API request from a specific date, or verify an expiration time in a scheduling system. If your timestamp is in milliseconds instead of seconds, divide it by 1000 before entering it here.
Frequently Asked Questions
Timestamps in milliseconds, common in JavaScript, need to be divided by 1000 before entering them here. For example, enter 1738368000 (seconds) instead of 1738368000000 (milliseconds).
A UNIX timestamp of 0 represents January 1, 1970, 00:00:00 UTC — known as the Unix Epoch. It's the reference point that all UNIX timestamps count from.
