Onul de Gabriel Ong

ONUL converts selected dates and times on webpages into your preferred timezone without sending data anywhere. By default it works manually: select text such as "5pm EST", "23:59", or "tomorrow at 5pm", open the ONUL popup, and click "Convert selection on this page".

If you want instant inline conversion on a specific website, you can enable live conversion for that site only. ONUL stores preferences such as timezone, 24-hour format, pinned comparison zones, ignored domains, and theme locally in the browser. It also supports right-click conversion from the context menu.
