I would like to be able to fuse all the events from one iCloud calendar together with all the events in a second iCloud calendar, so that all the events are contained in one calendar
I ended up with duplicate iCloud calendars from different devices, with all events from one old device ending in 2023 and recent events from a different device in a second iCloud calendar. I want to fuse them into a unified calendar. There are thousands of events, so manually changing all the calendars for each even would take a long time. I have about 30 of these duplicate calendars and want to find some simple way of merging two calendars into one.
