You can set up a block of appointments on your calendar that other people can reserve. For example, professors can invite their students to reserve time during office hours each week.
Appointment slots are useful when you don’t know who needs to meet with you, but you want to make yourself available. You can offer people a block of time on your calendar that they can book time slots within. For example, you can set aside 2 hours that you’re available to meet with people in 30-minute slots. Others can then book one of the 30-minute slots within that time that works best for them.
When someone reserves one of your appointment slots, the reserved slot shows up as an event on their calendar and inside the larger block on your calendar.
To Create Appointment Slots:
- on a computer, open Google Calendar.
- Make sure that you’re in Week view or any Day view.
- Click anywhere in the calendar. In the event box that pops up, click Appointment slots.
- Enter the details, including a title, and pick the calendar where you want the event to show up.
- To add more information, like a location or description, click More options.
Tip: If you want to make the appointment block repeat, do so before you invite others to reserve a slot. When you make an existing appointment block with reserved slots repeat, the reserved slots get duplicated as new slots and double booking can occur. Learn how to make events repeat.
