Unix Timestamp Converter
Convert Unix epoch timestamps to readable dates, and dates back to timestamps.
Current Unix time
Timestamp → date
Date → timestamp
What is Unix time? The number of seconds since 1 January 1970 00:00:00 UTC (the “epoch”), ignoring leap seconds. JavaScript and many APIs use milliseconds instead — this converter detects the unit from the number of digits.
About the Unix Timestamp Converter
The Unix Timestamp Converter turns epoch time — the number of seconds or milliseconds since 1 January 1970 UTC — into a readable date in UTC and your local time, and converts dates back into timestamps. Developers use it to debug logs, APIs, databases and JWT expiry times, and to check exactly when an event happened.
How to use the Unix Timestamp Converter
- Paste a Unix timestamp in seconds or milliseconds.
- Read the date in UTC and in your local time.
- Or enter a date and time to get its timestamp.
- Copy the value you need.
Frequently asked questions
What is a Unix timestamp?
A Unix timestamp counts the seconds that have passed since 00:00:00 UTC on 1 January 1970 (the Unix epoch). It is a simple, time-zone-free way for computers to store moments in time.
How do I tell seconds from milliseconds?
Current timestamps in seconds have 10 digits, while millisecond timestamps have 13. The converter detects which one you pasted.
What is the year 2038 problem?
Systems that store timestamps as signed 32-bit numbers overflow on 19 January 2038. Modern systems use 64-bit numbers, which avoids the problem.
