Timestamp / Unix Time Converter
Convert Unix timestamps to readable dates and back, in one input.
Or build a date manually
How to use the Timestamp / Unix Time Converter
- Paste a Unix timestamp (seconds or milliseconds) or an ISO 8601 date string into the input box.
- Or click Now to fill in the current Unix timestamp.
- The result appears automatically a moment after you stop typing, showing Unix (seconds), Unix (milliseconds), Local, UTC, and ISO 8601 together.
- Click Copy next to any row to copy just that value.
- If your input can't be parsed, an error explains exactly what's wrong.
How This Tool Works
Type a Unix timestamp (in seconds or milliseconds) or an ISO 8601 date string into the single input box, and the tool automatically detects which one you typed.
The parsed result always shows all five representations of that moment at once — Unix seconds, Unix milliseconds, your local time, UTC, and ISO 8601 — so you don't need to convert twice to get the form you need.
