The default working calendar within Microsoft Project is for working Monday to Friday from 8am to 5pm with an hour for lunch. If this is not the standard hours worked by your organisation, you may want to change the default calendar so that it reflects your standard hours for each new project.
In MS Project 2010, to change working time, go to the Project tab, then in the Properties group, click Change Working Time.
Use the Exceptions tab for non-working times like Bank Holidays – type the name of the exception and select the Start and Finish dates.
Use the Work Weeks tab to set the default working/non-working times:
- Click on the Default row and click the Details button.
- For working days, select the appropriate days of the week (select adjacent weekday names by dragging or non-adjacent days by holding down the Ctrl key).
- For these selected days, choose the third option Set Day(s) To These Specific Working Times.
- Type in the relevant Start and End times
- For non-working days, select the relevant days of the week and choose the second option Set days to non-working time.
- Click OK to complete your changes.
At the bottom of the Change Working Time dialog box, click Options.
Change the Default start time, Default end time, Hours per day, Hours per week and Days per month as appropriate to match what you have done in the Change Working Time dialog box.
Click OK twice.
To change the default working time for all new projects, open the good project plan with the required working times, then:
Click File then in the Info section, click Organize Global Template.
Click the Calendar tab. There should be two sides – the lhs will be the original default settings created by MS Project (says Global.mpt at bottom), the rhs covers the Calendar we created on Friday. Click Standard on rhs and then click Copy. You will get a message asking if you are sure this is what you want to do. Say Yes. When it has done so, close the dialog box. Now it should work for all new projects.
