Frequently Asked Questions
Everything you need to know about the Unix Timestamp Converter.
How does the timestamp converter work?
Enter a Unix timestamp to see the date it represents, or pick a date to get its timestamp. Change either field and the other updates instantly.
Is it free?
Completely free, no sign-up, downloads, or limits.
What is a Unix timestamp?
The number of seconds (or milliseconds) elapsed since the Unix epoch, midnight UTC on 1 January 1970. It's a common, timezone-independent way to store a moment in time.
Does it handle seconds and milliseconds?
Yes. It auto-detects whether your timestamp is in seconds or milliseconds, and you can switch manually.
Does it show UTC and local time?
Yes, every result is shown in both UTC and your local timezone, clearly labelled, along with your detected UTC offset.
What other formats does it show?
The ISO 8601 string and a relative "time ago" form, alongside the Unix timestamp.
What's the current Unix time?
A live readout shows the current Unix timestamp ticking in seconds and milliseconds, which you can copy in one click.
Is my data sent anywhere?
No. Everything is converted locally in your browser; nothing is sent to a server.
Is my data stored?
No; nothing is stored.
Does it work on mobile?
Yes, fully responsive; inputs and results fit the screen without overflow.
