In Maximizer, you can customize your calendar to fit your work schedule. If you are one of the lucky ones to only have to work a few times during the week, or a few hours during the day, this can make your calendar a little bit more aesthetically pleasing.
Two of the most useful functions are the working day and working hour options in the preferences menu.

Working day
Select which days you work. Any day left unselected will be red in the weekly and monthly views, so you can quickly identify which days you are in and which days you are not.
You can also choose to not show non-work days in the weekly view by selecting the "Show non-work days in the weekly view" option in the Options area. That way, you can look at a weekly view of your work related activities while not being distracted with your weekly golfing sessions on your midweek day off.
Working hours
Set your working hours here. The range specified in the from and to drop down lists will be a different colour than the hours that are outside the range. Also, any appointments created outside of the range will appear at the top or bottom of the daily view saying you have x number of appointments before/after your start/end time.
