What is a Unix Timestamp?
1627893600 converts to August 2, 2021
A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 (UTC). It's widely used in programming, databases, and APIs to represent time in a consistent, timezone-independent format.

Technical Details
Seconds vs Milliseconds: Unix timestamp counts seconds since January 1, 1970 00:00:00 UTC (Unix Epoch). 10-digit numbers represent seconds, while 13-digit numbers represent milliseconds.
Timezone Handling: Timezone conversion uses IANA timezone database with automatic daylight saving time handling. UTC is the reference timezone for all calculations.
Format Options: Supports ISO 8601, RFC 2822, and custom date formats. Format patterns follow standard date formatting conventions (YYYY-MM-DD HH:mm:ss).
Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 (UTC), also known as the Unix Epoch. It's a standard way to represent time in computing.
What's the difference between 10-digit and 13-digit timestamps?
10-digit timestamps represent seconds since the Unix Epoch, while 13-digit timestamps represent milliseconds. The tool automatically detects which format you're using.
How do I convert timestamps to different timezones?
Select your desired timezone from the dropdown menu. The tool uses the IANA timezone database and automatically handles daylight saving time.
Can I convert timestamps to ISO 8601 format?
Yes, the tool supports ISO 8601, RFC 2822, and custom date formats. You can also create your own format using standard date formatting patterns.
What is the 2038 problem for Unix timestamps?
The 2038 problem affects 32-bit systems where timestamps cannot represent dates after January 19, 2038. Modern 64-bit systems extend this limit significantly.
