Did you program a rest day for your client, but at the last minute they decided there is no rest for the wicked?
Go ahead into your client's calendar, and select the rest days you would like to delete.
Once those are selected, head down to the tool bar at the bottom of your screen.
Make sure to click AND hold on the trash can until the red progress bar goes across the bottom of the icon.
VWALAH! Rest day gone.
