Unix Timestamp Converter
Convert between Unix timestamps and readable dates. 100% private.
Current Unix Timestamp
1791545561
A Unix timestamp counts the number of seconds (or milliseconds) since January 1, 1970 UTC — the standard way computers, databases, and APIs represent a moment in time internally. This tool converts between that raw number and a human-readable date, in both directions.
Everything happens locally using your browser's own date engine — no data is sent anywhere.
Step-by-step instructions
- 1
Pick a unit
Choose whether you're working with seconds or milliseconds — APIs and databases vary.
- 2
Convert timestamp → date
Paste a timestamp to see the equivalent readable date and time.
- 3
Convert date → timestamp
Pick a date and time to get its Unix timestamp.
Common use cases
Debugging APIs and logs
Quickly see what date a timestamp in a log file or API response actually refers to.
Database queries
Convert a human date into the timestamp format your database expects, or vice versa.
Scheduling and expiry checks
Verify token expiry times, cron schedules, or cache TTLs expressed as timestamps.
Tips for best results
- A classic gotcha: JavaScript's Date.now() and many APIs use milliseconds, while Unix/Linux and many backend systems use seconds — check which one your data actually uses before converting.
Frequently asked questions
What timezone does this use?
Dates are shown in your browser's local timezone; the timestamp itself is always timezone-independent (UTC-based).
Does this tool send my data anywhere?
No — all conversion happens locally in your browser using standard JavaScript date functions.
