Free Unix Timestamp Converter Online
A free Unix timestamp converter: turn epoch timestamps into dates — and dates back into timestamps.
Free tool · No sign-up · Private
Seconds or milliseconds are detected automatically.
Formats & limits
What this tool handles
Straightforward limits, stated plainly.
Auto second/ms detection
Paste 1791369600 or 1791369600000 — the tool figures out which unit you meant from the digit count. No toggle to get wrong.
Local + UTC + relative
Every timestamp shows your local time, the UTC equivalent, and a human label like “2 hours ago” or “3 days from now”.
Live now ticker
The top card ticks every second with the current epoch in both units, so you can grab “right now” without opening a terminal.
Date → timestamp
Pick any date and time with the calendar control to get its epoch value in seconds and milliseconds instantly.
How it works
Three steps to converted
Grab the current timestamp
The live ticker at the top shows right now in seconds and milliseconds — hit the copy button to grab it.
Convert either direction
Paste a timestamp to read it as a date (local time, UTC and a relative “3 days ago” label), or pick a date to get its timestamp.
Use it in your code
Drop the timestamp into your API request, database query, or log search — no timezone math required on your end.
Use cases
When timestamp conversion helps
Read log timestamps
Server logs store events as epoch integers. Paste one to see exactly when it happened in your timezone.
Debug API responses
JSON payloads often carry created_at as a timestamp. Convert it in one paste instead of writing a throwaway script.
Schedule cron jobs
Pick a future date and get its epoch value for schedulers, TTL fields, and cache-expiry settings.
Check token expiry
JWT exp claims are epoch seconds. Convert yours to see when your token actually expires — and how long you have left.
Database queries
Querying a created_at column by epoch? Get the exact value for your date range without mental timezone math.
