About this tool
A free online Unix timestamp converter that helps developers and engineers instantly convert between Unix epoch time and human-readable dates. Unix timestamps (also called epoch time or POSIX time) represent time as a single number—the number of seconds since January 1, 1970, 00:00:00 UTC. It's the standard way computers store and transmit dates across systems.
Our converter makes it simple to work with Unix timestamps. Paste any Unix timestamp and instantly see it converted to human-readable format in both UTC and IST (Indian Standard Time, UTC+5:30). Going the other direction, enter any date and time using the date-time picker and get the corresponding Unix timestamp.
The tool includes a live Unix timestamp clock that updates every second, showing you the current epoch time. This is useful for understanding how Unix time progresses and for getting the current timestamp quickly. Perfect for debugging API responses that use Unix timestamps, understanding server logs, working with authentication tokens that use epoch time for expiry, and converting between time formats in development.
How to use this tool
View the current Unix timestamp
See the live Unix timestamp clock at the top that updates every second. This shows you the current epoch time in real-time.
Enter a Unix timestamp
Paste any Unix timestamp (in seconds) in the left field, or click "Use Now" to convert the current moment.

The tool instantly displays the date and time in UTC, your local timezone, and IST. Copy any result with one click.
Or enter a date to get the timestamp
Use the date-time picker on the right to select any date and time, and get the corresponding Unix timestamp.
Frequently Asked Questions
What is a Unix timestamp and why do computers use it?
A Unix timestamp (epoch time) is the number of seconds since January 1, 1970, 00:00:00 UTC. Computers use it because it's a single number that represents an exact moment in time universally, eliminating timezone confusion. It's easy to calculate time differences, sort events, and transmit across systems.
What's the difference between Unix timestamp in seconds vs milliseconds?
Unix timestamps are typically in seconds (epoch), but JavaScript and many web APIs use milliseconds for higher precision. This tool works with second-based Unix timestamps. To convert milliseconds to seconds, divide by 1000.
How do I interpret a Unix timestamp like 1234567890?
The timestamp 1234567890 represents Friday, February 13, 2009, 23:31:30 UTC. You can paste any Unix timestamp into this converter to see what date and time it represents. Use the "Copy" button to grab the formatted date for your documentation.
Why do dates show different times in UTC vs IST?
UTC is Coordinated Universal Time (zone zero), while IST (Indian Standard Time) is UTC+5:30. The same moment in time appears as different clock times in different timezones. Unix timestamps are absolute points in time; the display just changes based on your timezone.
How do I use Unix timestamps with JWT tokens?
JWT tokens include "exp" (expiration) and "iat" (issued at) claims as Unix timestamps in seconds. This converter helps you decode when a token was issued and when it expires. Use it to debug token expiry issues or understand authentication token lifespans.
