7 years ago Yes, you are right, it's a long-lasting feature request, but I didn't have enough time to do this. (You can find it here)
And the "replacement with default calendar" might be another option or another extension at all 😄 For example, personally, I like to have both calendars.
If you can help yourself and I, create a fork and make a pull request
Can you make check box in Preferences to change position (Centre or Left) ? I think it would be nice if hijri calendar can replace main calendar of gnome.
