The Sad State of Mac Calendar Scripting
AppleScript support with popular Mac calendar apps is surprisingly limited. With Apple Mail, it’s easy to write a script that operates on the selected e-mail messages, and I’ve written many such scripts. I’d like to do this same with calendar events. For example, sometimes I want to make the same change to one of the fields of all the selected events (since there’s no bulk edit inspector). Other times I want to reschedule by shifting all the events by the same amount of time. Sometimes I have a group of past events (e.g. for cooking a Thanksgiving dinner or traveling to a familiar location) and I want to start planning the next iteration by duplicating and shifting them to the future. When traveling east-west, I would like to check that the time zone information is entered consistently.
But this just doesn’t seem to be possible to script. With Apple Calendar and BusyCal, the scripting dictionary does not even let you access the selected calendar events. Readdle Calendars, which recently switched to a subscription, is not scriptable at all. With Fantastical, the dictionary looks promising but mostly doesn’t work:
