Unix Timestamp

Time

Convert Unix timestamps to/from human-readable dates

Paste a Unix timestamp in either seconds or milliseconds and it auto-detects which one you gave it by digit count, converting to a human-readable date shown in both your local timezone and UTC side by side. It runs the other direction too: enter a date and get the timestamp back for an API request, database query, or log filter, and a one-click "now" button grabs the current timestamp, handy when debugging why a comparison against `Date.now()` is behaving oddly. Everything happens locally using the native Date object, and the browser tool is built for one value at a time; bulk conversion across a dataset is better handled by scripting against the REST API or SDK in a loop.

How to use Unix Timestamp

  • 1.Paste a Unix timestamp (seconds or milliseconds) to instantly see it converted to a human-readable date in your local timezone and UTC.
  • 2.Enter a date/time to get its Unix timestamp equivalent for use in an API request, database query, or log filter.
  • 3.Use the "now" button to grab the current timestamp when writing test fixtures or debugging why a comparison against `Date.now()` is off.

Frequently asked questions

Does this handle both seconds and milliseconds?
Yes, the tool auto-detects whether a pasted timestamp is in seconds or milliseconds based on its digit count and converts accordingly.
Is my data sent anywhere?
No, all conversion happens locally in your browser using the native Date object — nothing is uploaded.
What timezone is shown?
Both your local timezone (detected from your browser) and UTC are shown side by side so you can compare directly.
Can I convert timestamps in bulk?
The browser tool is built for one value at a time; for bulk conversion, use the REST API or SDK in a script that loops over your dataset.
