What is Epoch Time?

Unix epoch time (also called POSIX time or Unix timestamp) is a system for tracking time as a running total of seconds. The count begins at the Unix Epoch on January 1st, 1970 at UTC. For example, the epoch timestamp 1700000000 corresponds to November 14, 2023, 10:13:20 AM UTC.

Epoch timestamps are widely used in programming, databases, APIs, and system logs because they provide a timezone-independent, compact way to represent a specific moment in time. Unlike human-readable date formats that vary by locale and timezone, epoch time is unambiguous.

How to Use This Converter

Epoch to Date

Enter a Unix timestamp in seconds (10 digits, e.g., 1741219200) or milliseconds (13 digits, e.g., 1741219200000). The tool automatically detects the format and displays the result in UTC, ISO 8601, and your local timezone.

Date to Epoch

Select a timezone from 17 presets or enter a custom IANA timezone identifier (e.g., Asia/Seoul, America/New_York). Fill in the year, month, day, and optionally hour, minute, and second. The converter outputs both epoch seconds and milliseconds along with UTC and ISO 8601 formats.
