Unix Timestamp Converter
Convert Unix timestamps to human-readable dates and vice versa.
What is a Unix Timestamp?
A Unix timestamp (also called POSIX time or Epoch time) is the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC. It is the standard way computers represent dates and times internally because it is timezone-independent and simple to calculate with.
How to Use This Tool
- Enter a Unix timestamp to convert it to a human-readable date and time.
- Or enter a date and time to get its corresponding Unix timestamp.
- Select your timezone for accurate local time display.
Current Timestamp
The current Unix timestamp is displayed and updated in real time, which is useful as a quick reference during development and debugging.
Common Use Cases
Unix timestamps are used in: database date fields, API responses, log files, JWT expiration claims, and any cross-timezone scheduling. Converting them to readable dates is an everyday developer task.
Frequently Asked Questions
What is the Unix epoch?
The Unix epoch is January 1, 1970, 00:00:00 UTC. All Unix timestamps count seconds from this moment.
What is the maximum Unix timestamp?
On 32-bit systems, Unix timestamps overflow on January 19, 2038 (the "Year 2038 problem"). 64-bit systems extend this far into the future.
