How it works

- Drag the bar until both sit inside the shaded 9–18 working band, if you can.
- Add more cities, or copy the result as text for the invite.
Why nothing is uploaded
Every operation on this page is done by code running inside your browser tab, using the same engine that renders web pages. The file is read from disk into your tab’s memory, transformed there, and written back out as a download. It is never sent anywhere — not to us, not to a third party.
Verify it yourself
- Open your browser’s developer tools (F12) and select the Network tab.
- Load your file and run the tool.
- The only requests you will see fetch the tool’s own code — and, for a few heavy tools, their open-source engine from a public CDN — plus one small page-view ping to loreatec.jp (page address and title, nothing more). None of them carry your file.
Frequently asked questions
What is the time difference between Sydney and London?
It depends on the date, because either city may be on daylight saving. Rather than quote a number that goes stale twice a year, this tool shows the live difference for the date on the bar — move it and watch the gap change around clock-change dates.
Do I need an internet connection?
Only to load the page the first time. The conversion itself runs in your browser from its built-in time-zone data, so nothing is sent anywhere and it works offline afterwards.
