Project Summary Task and Calendars in Microsoft Project 2016



I have interesting question from my Blog reader:

“How does one change the calendar for the Project Summary Task? The schedule is developed and has a calendar, other than the standard calendar, associated with all the tasks, but cannot change the calendar for the Project Summary Task.”

The answer is: It can not be done, and it should not be done. I will show you that in MS PROJECT 2016. First I will create very simple Project:


O.K. According to my example (from my Blog reader) I will now change Calendar and I will set it up to 24 Hours Calendar to all Task:


and I will get:


as you can see, for Task 2, and Task 3 Start and End Dates are changed. this makes sense because I changed Calendar. Now, if I try to change Calendar to Project Summary Task, I will get:


As you can see, Calendar field is disabled for editing. Why? Project Summary Task is to Show you in one row how many days will your Project lasts, how many hours will it need, how much money will it be spent, when will the Project Start and End etc. When we are considering Calendar, usually you will have hundreds, even thousands Tasks in a single Project, and they will have various Calendars. So you have to set those various calendars for specific Tasks as I did in my example above. But, you don’t need to do that for Project Summary Task since it is calculated and it is here for (very useful) information.

So, to conclude it doesn’t make any sense to put Calendar to Project Summary Task.

Hope this helps.
