Unix milliseconds converter
Convert Unix epoch milliseconds to a human date and convert any date to epoch milliseconds. Free timestamp millisecond converter.
Seconds vs milliseconds
Unix time is often stored in seconds, but JavaScript and many APIs use milliseconds. A millisecond timestamp is 1,000 times larger than a Unix seconds timestamp.
Developer-friendly conversion
Use this tool when debugging API payloads, logs, analytics events, database records, or browser timestamps that store time as epoch milliseconds.
Local display
The converted date is shown in your local browser time zone. The millisecond number itself represents an absolute moment in time.
