By using the recurring event feature, you can manage them as less than 24 events. iCloud manages this efficiently. If you wish to delete one, you can delete all future events at one time.
Creating a recurring calendar event
Create a calendar event for your first Chime with these settings:
- name: Chime
- starts: 4:00
- ends: 4:01
- repeat: Every Day
- alert: At time of event
Since there are 24 hours in the day, you will need to create 24 of them for each hour in a single day.
Uncheck that calendar in your Calendar app to hide it so you don't have to see it:
Perfect! Now your calendar still looks nice and clean.
Deleting a Chime
If you want to delete a chime, check the Chime calendar to make it visible again. Select an event and press the Delete key:
Click Delete All in the prompt:
Now your Chime is removed from all future days:
