In MaxScheduler you can specify the schedule to reflect the hours that your business is open and operating for. This adjustment is done through menu Configuration | Adjust Work Hours. The screen looks like such:
In the configuration screen menu Configuration | Change Schedule Layout, there is an option called 'Row time increment'. This number controls how much time is covered with one row of the schedule. For example '1' means that each row represents one hour of time. In the Work Hours Editor you specify how many rows are displayed for each day. If you don't want a day to be displayed choose the value '0'.
Keep in mind that if you set Row time increment to 24 hours set the Work day hours to 1 for each day. If this is not done, you will experience usability errors.
