Hello there We have read the message We try to help.

Thunderbird stores the calendar data of local calendars in your profile folder in the file calendar-data/local. sqlite , an SQLite database file.

If you right-click any calendar in the left pane of the Calendar tab, e.g. Home, there is an entry 'Show only Home'. That will hide all but Home, and then you can unhide individual calendars by clicking the eye icon that appears when you hover next to a calendar.

Hello there

To be able to view these multiple calendars or individually one after the other or in a single creation of them, you can use a split view and place these calendars in the way you want them to be want.

I can't find it at Thunderbird Firefox extensions has a Split View extension.

With https://bugzilla.mozilla.org/show_bug.cgi?id=1733959 there will be such a thing during account creation. But AFAIK nothing yet for normal operations.

I suggest you submit the idea to https://connect.mozilla.org/t5/ideas/idb-p/ideas/tag-name/calendar
