Try this example

Steps
  1. 1Paste 1729345200 into the timestamp box.
  2. 2The tool auto-detects this is seconds (10 digits) and displays the matching local and UTC times.
  3. 3If your timestamp ends with three more zeros (e.g. 1729345200000), it is milliseconds. The tool handles that automatically.
Expected result
Input:  1729345200

FAQ

Seconds or milliseconds?▼

Unix timestamps come in two flavors. POSIX standard is seconds (10 digits, e.g. 1700000000). JavaScript and Java use milliseconds (13 digits). The tool auto-detects based on length, so 1700000000 is treated as seconds and 1700000000000 as milliseconds.

What time zone does this use?▼

The output shows your local browser time zone and UTC side by side. You never have to guess.

What is epoch time?▼

Seconds (or milliseconds) since 1970-01-01 00:00:00 UTC. It is the most common format for storing timestamps in databases and APIs.
