Get the best out of Timestamp to Date: every option explained, a worked example, and what to check when the output is not what you expected.
Updated July 31, 2026
What it does
Convert millisecond timestamps to localized date strings. It runs entirely in your browser — your input never leaves your device.
Options
Every setting this tool exposes, straight from the code that validates it.
| Option | Type | Default | What it does |
|---|---|---|---|
timestamp | number | — | Millisecond timestamp. Required. |
Worked example
Run these settings on the tool page:
timestamp:2
You get:
Thursday, January 1, 1970 at 12:00:00 AM UTC
Troubleshooting
- Nothing happens / the output stays empty.
timestampis required — the tool waits until you provide it. - It is slow on very large input. Everything runs in your browser, so speed depends on your device. Very large inputs are best split up, or run through the API where the work happens on our servers.
Automating it
The same logic is available as a REST endpoint, so you can run it from a script, a CI job or your own app.
Bashcurl "https://api.toolsxpo.com/v1/timestamp-to-date" \ -H "Authorization: Bearer $TOOLSXPO_KEY"
It costs 1 credit per successful call. See the full endpoint reference, or try it in the playground.
