- Enter or paste a start date, end date, count and output format into the tool.
- Adjust the available options so they match the format and result you need.

Private processing and offline access
This tool does not submit your input to a conversion server. Processing takes place inside the browser using local JavaScript and standard Web APIs. After the PWA has been installed or cached, the page and its core features remain available without an internet connection. Closing or clearing the page removes unsaved input; the tool does not create an account or cloud history.
Tips for accurate results
- Confirm whether the target system expects UTC.
- Date-only output may repeat more often in a narrow range.
- Random test dates should not be mistaken for real events.
