See the current Unix timestamp ticking live, convert any epoch value to a human-readable date, or convert a date back to an epoch. Select your timezone and switch between seconds and milliseconds instantly.

When to Use the Epoch Converter

Use the epoch converter when debugging API timestamps, reading database time fields, converting log file timestamps, setting cache expiry times, or verifying JWT token expiration dates.

Tips

  • JavaScript timestamps are in milliseconds — divide by 1000 before comparing with Unix timestamps from other languages.
  • If a timestamp looks like 1712345678000, it is likely in milliseconds. If it looks like 1712345678, it is in seconds.
  • Store timestamps in UTC and convert to local time only for display — this avoids timezone bugs.
  • Epoch 0 is 1 January 1970 00:00:00 UTC. Negative values represent dates before 1970.

Frequently Asked Questions

What is a Unix epoch timestamp? ▾

A Unix epoch timestamp is the number of seconds that have elapsed since 1 January 1970 00:00:00 UTC. It is used by virtually every programming language and operating system to represent time as a single number.

Should I use seconds or milliseconds? ▾

Most Unix systems and languages like Python, PHP and C use seconds. JavaScript uses milliseconds (Date.now()). Our converter auto-detects which you are using based on the digit count.

What happens at the Year 2038 problem? ▾

On 19 January 2038, a 32-bit signed integer overflows. Most modern systems use 64-bit timestamps, which are safe for billions of years. This converter uses JavaScript's 64-bit Date object and is not affected.

Can I convert dates in different timezones? ▾

Yes. Select any timezone from the dropdown to see the converted date in that timezone. The underlying epoch value stays the same — only the displayed date and time change.

Is the live clock accurate? ▾

The live clock uses your device's system time. It is typically accurate to within a few milliseconds of your OS clock.
