How to Use the Unix Timestamp Converter

A Unix timestamp (epoch time) is the number of seconds elapsed since January 1, 1970 00:00:00 UTC — the Unix epoch. It is a format engineers encounter daily in server logs, databases, and API responses.

  • Current Unix Time: The panel at the top displays the current epoch seconds, milliseconds, local date/time, and UTC date/time, updated every second. Click any value to copy it.
  • Timestamp → Date: Enter a Unix timestamp (seconds or milliseconds) in the first input field. The local date/time, UTC date/time, and ISO 8601 format are shown automatically.
  • Date → Timestamp: Pick a date and time in the second input field and the corresponding Unix seconds and milliseconds are calculated instantly. Use the "Now" button to fill in the current date and time.

Worked example: turning a log number into a date

Say a server log contains the 10-digit number 1700000000. Paste it into the timestamp field and, because it has 10 digits, it is auto-detected as "seconds" and instantly shows the local date/time 2023/11/15 06:13:20, the UTC date/time 2023/11/14 22:13:20 UTC, and ISO 8601 2023-11-14T22:13:20.000Z. Pasting the millisecond form 1700000000000 (13 digits) yields the same moment. Note that "Local Date & Time" uses your device's time zone, while "UTC Date & Time" and ISO 8601 are in Coordinated Universal Time (UTC).

Common use cases

  • Converting epoch seconds recorded in server logs or databases into a human-readable date
  • Inspecting and debugging timestamps in API responses or JSON payloads
  • Looking up the Unix timestamp for a specific date to use in a query or filter

Frequently Asked Questions

Is my input data sent to a server?
No. All conversion processing happens entirely in your browser. Your input is never transmitted to or stored on any server, so you can use this tool with confidence.
What is the difference between seconds and milliseconds?
Seconds count the number of seconds elapsed since January 1, 1970 00:00:00 UTC. Milliseconds are 1000 times that value, used by JavaScript's Date.now() and APIs that require millisecond precision. Current second values are typically 10 digits; millisecond values are 13 digits. Use the unit toggle (Seconds / Milliseconds) to convert correctly.
Does this tool work on smartphones?
Yes. The tool works in any browser on smartphones, tablets, and PCs. No installation or account is required.
