January 1, 1970 at 12:00:00 AM
Supports Unix timestamps in seconds, milliseconds, microseconds, and nanoseconds.
Learn how to use this tool to convert Unix timestamps to dates or dates to timestamps.
Choose between 'Timestamp → Date' or 'Date → Timestamp' from the tabs at the top.
For timestamp conversion, enter numbers. For date conversion, select the date and time.
When converting timestamps, choose the appropriate unit: seconds, milliseconds, microseconds, or nanoseconds.
The converted result is displayed automatically. You can see both GMT and local time.
A Unix timestamp is an integer value representing the number of seconds elapsed since January 1, 1970, 00:00:00 UTC. This value allows for numerical calculation of time flow, helping various systems like operating systems, databases, and APIs to efficiently process time data. It is also location and timezone independent.
Unix timestamps can be represented in various date/time formats. These formats are defined according to standardized rules and are used to consistently convey time data between different systems.
| Human Readable Time | Seconds |
|---|---|
| 1 hour | 3600 seconds |
| 1 day | 86400 seconds |
| 1 week | 604800 seconds |
| 1 month (30.44 days) | 2629743 seconds |
| 1 year (365.24 days) | 31556926 seconds |
Current 32-bit systems limit the maximum Unix timestamp value to January 19, 2038, at 03:14:07 UTC. Beyond this point, the timestamp will overflow and become negative, potentially leading to system errors or incorrect dates. This is known as the '2038 problem', and transitioning to 64-bit systems is essential to resolve it.
