How to Convert Unix Timestamps
- 1To convert a timestamp to a date: enter the Unix timestamp in the left field and click "Convert".
- 2To convert a date to a timestamp: enter a date string (ISO 8601 format like 2024-01-15T12:00:00Z) in the right field and click "Convert".
- 3Click "Use Now" to quickly insert the current timestamp.
- 4The result shows the conversion in four formats: Unix timestamp, ISO 8601, local time, and UTC.
- 5Both seconds and milliseconds timestamps are automatically detected.

Frequently Asked Questions
What is a Unix timestamp?▼
A Unix timestamp (also called epoch time or POSIX time) is the number of seconds that have elapsed since January 1, 1970 at 00:00:00 UTC. It is a widely used format for representing time in computing and is independent of time zones.
What is the difference between seconds and milliseconds timestamps?▼
A seconds-based timestamp has 10 digits (e.g., 1700000000), while a milliseconds-based timestamp has 13 digits (e.g., 1700000000000). This tool automatically detects which format you're using and converts accordingly.
What is the Year 2038 problem?▼
The Year 2038 problem affects systems that store Unix timestamps as 32-bit signed integers. The maximum value (2,147,483,647) corresponds to January 19, 2038. After this date, the counter overflows. Modern 64-bit systems are not affected by this issue.
What date format should I use for input?▼
Use ISO 8601 format for best results: YYYY-MM-DDTHH:mm:ssZ (e.g., 2024-01-15T12:00:00Z). You can also use common formats like "January 15, 2024" or "2024-01-15". The 'Z' suffix indicates UTC time.
Why does the current timestamp keep changing?▼
The current Unix timestamp display updates every second in real-time, showing the live epoch time. This is useful for developers who need to quickly reference or copy the current timestamp.
