Unix Timestamp Converter
Convert Unix seconds or milliseconds to local or UTC dates, and convert date input back to both timestamp units.
Key features
- Updates the current Unix timestamp in seconds and milliseconds every second.
- Auto-detects seconds versus milliseconds by magnitude or accepts an explicit unit.
- Displays a timestamp as local or UTC locale text and ISO 8601.
- Interprets a date and time as local time or UTC and returns both timestamp units.
How to use
- Choose Timestamp to Date or Date to Timestamp.
- Enter a value and set the unit or local-versus-UTC interpretation.
- Copy the date or numeric result you need.
Examples

Privacy
Reading the browser clock and calculating dates or timestamps happen in your browser.
Requirements
Auto unit mode treats absolute values at or above one trillion as milliseconds and smaller values as seconds.
Common questions
- How does auto mode distinguish seconds from milliseconds?
- Absolute values at or above one trillion are treated as milliseconds. Choose seconds or milliseconds explicitly for ambiguous values.
- Can I view both UTC and local time?
- Yes. Display a timestamp as localized or ISO 8601 output using local time or UTC.
