How it works

1

Enter epoch or a date

Paste a Unix timestamp, or pick a local date and time. 10 digits are seconds; 13 digits are milliseconds.

2

Read every format

Local time, UTC, ISO 8601, RFC 2822, and relative time update as you type. No convert button.

3

Copy what you need

Copy seconds, milliseconds, or a formatted date. Use now snaps to the current epoch.

What is epoch time?

Epoch time, Unix time, and Unix timestamp are the same idea: seconds since the Unix epoch (1 Jan 1970 UTC). APIs, logs, and databases often store this number. An epoch converter maps it to a human date, and the other way, from a calendar date back to Unix seconds.

Why use this tool

  • Epoch converter runs in a browser tab.
  • Unix seconds and milliseconds in one view
  • UTC, ISO 8601, RFC 2822, and your timezone
  • No account. Unlimited on the free plan

Questions

What is a Unix timestamp (epoch)?

A Unix timestamp, also called epoch time, is the number of seconds since 1 January 1970 00:00:00 UTC. This epoch converter turns that number into a calendar date and back.

Seconds or milliseconds?

A 10-digit value is Unix seconds. A 13-digit value is milliseconds. This converter detects both.

Which timezone is used?

Local date and time use your browser timezone. UTC and ISO 8601 are timezone-independent.

What happens on 19 January 2038?

32-bit systems that store time as a signed 32-bit Unix second overflow at 03:14:07 UTC that day. This tool uses JavaScript Date (64-bit milliseconds), so dates after 2038 still convert here.

Do I need an account?

No. Open the epoch converter and use it. There is no daily cap on this tool.
