🕰️ Unix Timestamp Converter
Convert a Unix timestamp (seconds since January 1, 1970 UTC) into a readable date and time, or convert any date into its Unix timestamp — useful for developers, log files, and debugging.
How the Unix Timestamp Converter works
Unix time counts seconds elapsed since the "epoch" (00:00:00 UTC, January 1, 1970). This tool converts in both directions using your browser's own date engine, and shows the result in both UTC and your local time zone.
Step-by-step calculation
- 1Enter a Unix timestamp or a date.
- 2Seconds are counted from January 1, 1970 UTC.
- 3See the result in UTC and your local time.
Worked example
The timestamp 1,700,000,000 is Tuesday, November 14, 2023 at 22:13:20 UTC.

Why use a Unix Timestamp Converter?
Debug logs, databases and APIs that store time as numbers.
Important factors that can affect your results
- Seconds versus milliseconds (13-digit numbers are milliseconds).
- Your local time zone and daylight saving.
- Leap seconds are not counted in Unix time.
Frequently asked questions
What is the Unix epoch?
January 1, 1970, 00:00:00 UTC — the reference point Unix time counts seconds from.
Does this handle timestamps in milliseconds?
Enter seconds for standard Unix time; if your timestamp looks like 13 digits, it's likely milliseconds — the tool detects and handles both.
