Ever find yourself asking When am I available for _________ ?
If you have events right before the targeted time, a yellow label lets you know that it might not be the best day to schedule something. For example, September 3rd shows that you have something either right before or after the targeted time of 7:00a-8:00; this might not be the best day to schedule breakfast with someone. If a date on the calendar is labeled green, you're good to go.. You've got nothing ahead or after your targeted time.
The section above the calendar allows you to navigate between saved events and times. For example, if you save an event for Breakfast, you can add different targeted times like 7:00a-8:00a, 8:00a-9:00a etc. Swiping allows you to cycle through saved events/times
