Unix Timestamp Converter — Convert Epoch to Date and Back

What is a Unix Timestamp?

Unix timestamp (or Epoch time) is the number of seconds that have elapsed since 00:00:00 UTC on January 1, 1970. This is the most popular way to represent time in programming, databases, and APIs.

Example: 1700000000 = November 14, 2023 at 22:13:20 UTC.

Metoolzy Timestamp Converter helps you convert back and forth between timestamps and human-readable dates and times.

Frequently Asked Questions

What is the difference between timestamp seconds and milliseconds?

Traditional Unix timestamp is in seconds (10 digits). JavaScript Date.now() returns milliseconds (13 digits). The tool automatically detects both.

How do timezones affect this?

Unix timestamps are always UTC. The tool displays both Local Time (based on the browser’s timezone) and UTC for you to compare.

What is the Year 2038 problem?

32-bit systems store the timestamp as a signed int (max 2,147,483,647) → overflows on Jan 19, 2038. 64-bit systems are not affected.
