I will show you default setup for Working hours per day in Microsoft Project for the Web. Here is my Project:
OK, let me Create one Task with 8 days Duration:
As you can see, Task will start at Monday, 4/5/2020, and Finish at Monday 4/12/2020, e.g. it will be performed during the weekend, as well:
OK. Now I will create three Tasks: Task 7 hours, Task 8 Hours, and Task 9 hours with durations as show in the Picture below:
As you can see, 1 day is 8 hours. In Task 9 hours Finish date is 4/6/2020, and Start date is 4/5/2020, and in Task 8 hours Finish date is 4/5/2020, and Start date is 4/5/2020.
How is it so, and what if I want that my 1 day is 9 hours, but only from Monday to Friday?
Default Value is that Task is starting from 09:00 AM and finishing at 05:00 PM. To see that I should use Dynamics 365:
Now I will show you default working time. To do that I should go to settings:
and then to Calendar Templates:
Finally, I will get:
Project for the Web is using this Template if I do not have any other. It is default. Now I will going to create new Template with working hours from 09:00 AM to 06:00 PM, during working days. To accomplish that, first I have to create a resource with those working hours. I will call this Resource: Generic Resource (weekdays, from 09:00 AM to 06:00 PM).
First I will go to the Resource page in Dynamics 365:
Now I will create new Resource:
Now I have my Resource and I should setup working time like this.
Since those working hours are valid only till 3/28/2020, I will repeat those steps and I will follow those steps:
OK, now we should go back to the Settings:
I will call my Template: Weekdays Calendar from 09:00 AM to 06:00 PM:
OK. I am done here!
Now I will create brand new Project for the Web:
OK, let me Create one Task with 8 days Duration and Task 7 hours, Task 8 hours, Task 9 hours, and Task 10 hours:
You can see, that Task with 8 days duration is going to be finished at 4/15/2020 e.g. at Wednesday (so Saturday and Sunday are non working hours). Also, you can see that duration of one day is 9 hours, not 8 anymore!
Complicated? Maybe. Powerful? Oh, yes!
