About Unix Timestamps
A Unix timestamp (also known as Epoch time or POSIX time) is a system for describing a point in time. It represents the number of seconds that have elapsed since the Unix epoch (00:00:00 UTC on 1 January 1970), not counting leap seconds.
Common Uses
- Database systems often store timestamps as Unix time
- Programming languages use Unix time for date/time calculations
- Log files frequently use Unix timestamps for event recording
- APIs commonly return dates as Unix timestamps
Key Facts
- Timestamps can be in seconds (10-digit) or milliseconds (13-digit)
- The maximum 32-bit signed integer timestamp is 2,147,483,647 (2038-01-19)
- Negative values represent dates before 1970
- JavaScript uses milliseconds while many other languages use seconds
Frequently Asked Questions (FAQs)
A Unix timestamp is the number of seconds since January 1, 1970 (UTC). It is a standard way to represent time in computing.
Simply enter the Unix timestamp (e.g., 1719091200) into our tool, and it will display the equivalent date in UTC and your local timezone.
- In Linux/Mac: Run
date +%sin the terminal - In JavaScript: Use
Math.floor(Date.now() / 1000) - In Python: Use
import time; print(int(time.time())) - Or just visit this page - we display the live Unix timestamp!
Yes! Enter a timestamp like 1719091200000 (with milliseconds), and the converter will process it correctly.
- Check if your timestamp is in seconds (10 digits) or milliseconds (13 digits)
- Ensure you're not entering a future date beyond the supported range
Yes! Enter a human-readable date (e.g., June 23, 2025), and the tool will generate the corresponding Unix timestamp.
- Minimum:
0(January 1, 1970) - Maximum (32-bit systems):
2147483647(January 19, 2038 – "Year 2038 Problem") - Maximum (64-bit systems): Practically unlimited (~292 billion years)
