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 Unix timestamp?
Unix timestamp is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC. It's a standard way to represent time in computing.
What's the difference between seconds and milliseconds?
Unix timestamp is typically in seconds, but JavaScript and some systems use milliseconds (1000x larger). Our tool automatically detects and converts both.
How do I handle timezone conversions?
Our tool shows times in both UTC and your local timezone. Unix timestamps are always UTC-based, so timezone conversion happens during display.
What's the Y2038 problem?
32-bit systems will overflow on January 19, 2038, when Unix timestamp exceeds 2^31. Modern 64-bit systems extend this to year 292 billion.
Can I convert custom date formats?
Yes, our tool supports various input formats including ISO 8601, RFC 2822, and common date formats. It automatically detects the format.
