▶About Unix Timestamp Converter
A Unix timestamp (also called epoch time or POSIX time) is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC. It is the universal standard for representing time in operating systems, databases, and programming languages.
This free online Unix timestamp converter lets you convert between Unix timestamps and human-readable dates in real time. It supports both seconds and milliseconds, displays results in your local timezone, and provides one-click copy for instant use.
Common use cases: converting API response timestamps to readable dates, debugging time-related issues in server logs, generating epoch values for database queries and cron schedules, and comparing timestamps across different timezones.
▶Frequently Asked Questions
▶What is a Unix timestamp?
A Unix timestamp (also called epoch time) is the number of seconds elapsed since January 1, 1970 00:00:00 UTC. It is the standard way to represent time in programming, databases, and operating systems.
▶How do I convert a Unix timestamp to a date?
Paste your timestamp (in seconds or milliseconds) into the input field. The tool will instantly convert it to a human-readable date in your local timezone.
▶What is the difference between seconds and milliseconds timestamps?
A seconds-based timestamp has 10 digits (e.g., 1709654400) while a milliseconds-based timestamp has 13 digits (e.g., 1709654400000). JavaScript's Date.now() returns milliseconds, while most Unix systems use seconds.
▶What is the Year 2038 problem?
32-bit systems store Unix timestamps as a signed 32-bit integer, which will overflow on January 19, 2038 at 03:14:07 UTC. Modern 64-bit systems are not affected.
