How to Set Appointments at Quarter Hours for Google Calendar

By default, Google Calendar only lets you create appointments, or events, in hourly blocks, which can make scheduling an appointment in 15-minute intervals difficult. However, it is still possible to create an event with a quarter-hour time by editing that event upon its creation instead of outright creating that event. Using this method you can not only set up events in 15-minute intervals but for any time you want. In addition to setting up an event in a 15-minute interval, you can also end the event on one as well with the time block properly represented within your Google Calendar.

Open Google Calendar and click the hourly block of time closest to your quarter-hour appointment. For example, if your appointment is at 1:15 P.M., click the block of time from 1:00 - 2:00 P.M.

Click "Edit Event" from the pop-up window that appears onscreen.

Enter the quarter-hour time in the "From Time" field and set the end time in the "Until Time" field. Enter any other important information, such as location and description of the appointment, in the proper fields.

Click "Save" to save your quarter-hour appointment on your Google Calendar. You are automatically returned to your main calendar page and the proper length of time will reflect on the calendar.
