I have subsequently learned how to create custom calendars which can be set to have a 7-day work week.

That appears to work well.

However, in doing so, I created lots of calendars and I've now been told that there is no way to deltete my custom calendars.

I guess I could un-install PL and then re-install.

Hi Frank,

That is a good catch... we have made a note for the new re-written version to allow for the deletion of calendars.  We will need to make contingency for what to do if tasks/resources/projects are utilizing the deleted calendar.  

Best regards,

Similar problem with 7 day work week calendar. Can get a new calendar to be added - how do I change that new calender to be the one used for my project? It seems to always go back to the standard calendar.

How do we make the Project use a 7 day work week.

The project as a whole needs to use a 7 day work week by default.

At this point I am unable to get it to use anything other then "Default"


Unfortunatley, a ver frustrated and behind new user.

I just tested and it worked properly.  I created a project with a 7 day task. I created a new base calendar called 7 day and  made Saturday and Sunday as "Non default work time"   by highlighting the day and selecting the radio button.   You can assign that calendar to the Project and Task as the base calendar.  My  task scheduled today would have finished 1/3/14 with the standard calendar but with the 7 day calendar compressed 2 days and finishes 1/1/14.

Hi There,

It's working for me too now I read your instructions above. You have to double click the task, then click Advanced tab, then select the new Task Calendar for that task. I have added a 7 day calendar onto all my overseas shipping tasks and they are now showing the correct delivery dates. Nice feature to be able to assign different tasks to a different calendar.

Great Program

I can make a NEW Calendar as described above but the new "7 Day" calendar is not visible in the pull down menu to be assigned to the project.

What am I doing wrong?

I believe that I cam following the instructions as described above.

I am able to create a new 7 day calender. I can also assign this calender to my project. I also discovered to assign this calender to my ressources, at least to whom the 7 days apply. In my Gant chart the weekends did disappear as expected.
But the tasks are still drawn and calculated as if there still were weekends. So basically the whole calender thing had no effect at all on my planning. What am I doing wrong?
