BusyCal supports creating time-blocking events across multiple calendars to help manage your availability seamlessly.

Need to ensure your personal commitments don’t clash with work meetings? BusyCal’s "Block event on Calendar" feature (introduced in v2024.3.4) allows you to manage your availability effortlessly. For example, if you have a family gathering on your personal calendar, you can block that time on your work calendar, indicating to your colleagues that you’re busy without sharing personal details.

BusyCal ensures that time-blocked events stay in sync with the original event. Whenever you update the date, title, or details of the original event, these changes are automatically propagated to all associated blocking events. This works seamlessly across any calendar or account, ensuring that your availability is consistently managed and accurately reflected.

Block on Another Calendar

1. Select and Ctrl+click on any event.
2. Select a calendar from the "Block on calendar" sub-menu.
3. Choose how you want the event to appear:
   • Show as busy: This option will not copy the original event's title and notes and will simply state "[Busy]" as the title on the time-blocking event.
   • Include details: Alternatively, you can choose to copy the title and notes to the blocking event.

IMPORTANT: Blocking events are automatically updated with changes from the original event on the Mac where they were created. Manual changes to these events should be avoided, as they will be overwritten the next time the original event is updated.

Unblocking an Event

Unblocking is performed in the same manner by selecting the original event, then Ctrl+click > "Block on calendar" and select the same calendar. Alternatively, you can select a time-blocking event and press the delete key.
