How to use Unix Timestamp Converter
Paste your Unix timestamp (e.g., 1709283400) into the input field to convert it to a human-readable date.
Alternatively, select a human-readable Date and Time to instantly convert it into a Unix epoch timestamp.
Toggle between Seconds and Milliseconds depending on the programming language you are using (e.g., JS uses ms, PHP uses s).

Frequently Asked Questions
What is a Unix Timestamp?
A Unix Timestamp (or Epoch time) is the total number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC, not counting leap seconds.
Why does my timestamp show the year 54000?
This is a common error in JavaScript. JS uses milliseconds, but if you pass a 10-digit (seconds) timestamp to the Date object without multiplying by 1000, or vice versa, the dates will be wildly inaccurate.
What is the Year 2038 Problem?
Because 32-bit integers have a maximum value of 2,147,483,647, Unix timestamps stored in 32-bit systems will 'overflow' on January 19, 2038, causing systems to reset to the year 1901. Modern 64-bit systems have solved this.
