About the Unix Timestamp Converter
A Unix timestamp (also called epoch time or POSIX time) is the number of seconds that have passed since January 1, 1970 at 00:00:00 UTC. It is how computers, databases, APIs and log files commonly store dates, because a single number is easy to compare and independent of time zones.
The Unix Timestamp Converter shows the current timestamp live and converts in both directions. Paste a timestamp to see the date in your local time zone, in UTC, in ISO 8601 format and as a relative time like "3 days ago". It automatically detects whether the value is in seconds or milliseconds (as used by JavaScript and Java). Pick a date and time to get its timestamp for use in code, SQL queries or API requests.
How to use the Unix Timestamp Converter
- See the current Unix time at the top, updating every second.
- Paste a timestamp to convert it to a readable date.
- Or pick a date and time to get its Unix timestamp.
- Copy the values you need.
Frequently asked questions
Seconds or milliseconds: how do I know?
Current timestamps in seconds have 10 digits, while milliseconds have 13 digits. The converter detects this automatically.
What is the year 2038 problem?
Systems that store Unix time as a signed 32-bit integer will overflow on January 19, 2038. Modern systems use 64-bit values to avoid this.
Does a Unix timestamp include a time zone?
No. It always represents a moment in UTC; time zones only matter when displaying it as a local date.
