Limitations
- Timezone conversion uses the browser's Intl API — very old browsers may not support all zones.
- Dates before 1970 (negative timestamps) may display inconsistently across browsers.
- No bulk conversion — one timestamp at a time.

Frequently asked questions
Is this tool free?
Yes — completely free, no sign-up required. All conversion runs in your browser and nothing is sent to a server.
What is a Unix timestamp?
A Unix timestamp is the number of seconds (or milliseconds) that have elapsed since January 1, 1970, 00:00:00 UTC — the Unix epoch.
Should I use seconds or milliseconds?
Most APIs and databases use seconds. JavaScript's Date.now() uses milliseconds. The tool auto-detects based on the length of your input.
Can I convert in both directions?
Yes. Paste a timestamp to get a human-readable date, or pick a date to get the corresponding Unix timestamp.
Does it handle timezones?
Yes. You can view the date in UTC or your local timezone, and the tool shows both for clarity.
Do you store my timestamps?
No. Everything runs locally in your browser. Your data never leaves your device.
