Frequently Asked Questions
What is a Unix timestamp?
The number of seconds (or milliseconds) since January 1, 1970 UTC — the standard way computers store a moment in time.
Can I convert a timestamp back to a date?
Yes. Paste an epoch timestamp and the tool decodes it into a human-readable date and time.
Which date formats are supported?
Common formats like YYYY-MM-DD, MM/DD/YYYY, and full datetime strings are parsed automatically.
How are timezones handled?
Results show both UTC and your browser's local timezone, so you can see exactly when a moment falls in each.
Is my input sent to a server?
No. Conversion runs entirely in your browser — nothing you type leaves your device.
