My computer's Calendar.app displays two calendars: mine (DB) and my wife's (MM), shared via iCloud; both computers run High Sierra. The sharing works just fine.
But now there's a number appearing next to her calendar's name:
What's the meaning of this number "1"? And now that it's a day or two later, the number has increased to "12." I could imagine it represents new entries in her calendar, but then it should go away when I look at it…and it doesn't.
Following some trial and error, and additional reasoning, I can partially answer my own question:
(1) The events from a local calendar, on an iPhone ("On This Phone", I think it is referred to), are not backed up to the calendar-specfic area in iCloud. Here:
iCloud.com > Settings > (Advanced section) > Restore Calendars and Reminders
Although it doesn't say so explicitly, it makes sense that these iCloud calendar backups cover a user's iCloud calendars. (Plus, my attempt to restore such backups with a hope to see pre-merged, local calendars, failed).
Screen shot from iCloud.com:
(2) The iPhone backup (the complete backup of the whole phone), which in my case was being backed up to iCloud (rather than iTunes), would, I presume, include the local calendars and their events.
However, by time I'd got to looking at this, my oldest 'complete' iCloud backup was just a day old... which was after I merged the local calendars into iCloud calendars.
This problem started at a client of mine after they upgraded clients from 10.6 to 10.7 and up. Calendar was stable before this. Webcal finds all ldap users, calendar app on clients does not find everyone, and I have yet to find a pattern when who doesn't find someone else. Some cannot find very old ldap users, others cannot find an newly created ldap user. This when creating calendar events and inviting other users. By the looks of it, a bug in the calendar.app in macOS.

The arrow-into-a-tray symbol above also shows the number. When the symbol is clicked, a list appears, showing new entries on her calendar. When I click on an entry in the list, apparently to acknowledge it, the numbers decrease by one. So the numbers are notifications that a new entry or entries have been made on her calendar.
