I can live with the new calendar, but I'm a stylist and would like to be able to book appointments at least on the half hour. Is there a to make the new calendar schedule on the half hour?
When you open your calendar in order to create an event and hit the plus sign top right it will open up where you set the event. By holding down on the start time it will open up where you can set the time by any means you want be it quarter or half or hour and same with end time. Then hit done, That should do it.
The stock calendar that comes with all Apple devices gives you the option of actually selecting down to the minute!! Just select the hour first then you will see the minute option scroll on the right of the hour. How cool is that!
