About the Timestamp Converter
A Unix timestamp counts the seconds since 1 January 1970 UTC. Logs, APIs and databases store time this way, but humans need real dates — this converter does both directions.
It auto-detects seconds vs milliseconds and runs entirely in your browser.
Frequently asked questions
Seconds or milliseconds?
Both — the tool detects the magnitude and converts accordingly.
