Force a Task to Start on a Specific Day of the Month

Force a Task to Start on a Specific Day of the Month

Understanding the Scheduling Challenge

Suppose that I have a project that contains three build-related tasks named Build 1, Build 2, and Build 3. Following each of these Build tasks, there’s a 2-hour review meeting, represented by a Build Review Meeting task. And suppose that these Build Review Meeting tasks can only be held on the second Tuesday of the next available month.

The way to address this interesting and unique scheduling need is to create a custom Base Calendar that shows only the second Tuesday of each month as a working day. And after creating this custom calendar, I will need to apply it as a Task Calendar to the three Build Review Meeting tasks.

Creating a Custom Calendar

Complete the following steps to create the custom calendar:

  1. Click the “Project” tab to display the Project ribbon.
  2. Click the “Change Working Time” button to open the Change Working Time dialog.
  3. Click the “Create New Calendar” button to display the Create New Base Calendar dialog.
  4. Select the “Create new base calendar option, name the calendar “Second Tuesday of Each Month” for clarity and then click the “OK” button.
  5. At the bottom of the dialog, click the “Work Weeks” tab, and then ensure that the [Default] item is selected.
  6. Click the “Details” button to display the Details dialog.
  7. On the left side of the Details dialog, select the Monday, Wednesday, Thursday, and Friday items, and then select the “Set days to nonworking time” option.
  8. Click the “OK” button.
  9. In the Change Working Time dialog, click the “Exceptions” tab.
  10. In the calendar grid at the top of the dialog, select the date of the first Tuesday of the current month.
  11. In the Exceptions grid, select the first blank row, enter the name “First Tuesday”, and then press Tab key followed by the Right-Arrow key to navigate to the Start cell.
  12. Click the “Details” button to display the Details dialog for this exception.
  13. In the Recurrence Pattern section of the dialog, select the “Monthly” option, and then select the “First Tuesday” option.
  14. In the Range of Recurrence section of the dialog, enter “25” occurrences, and then click the “OK” button.
  15. Repeat this process for the third, fourth, and if available, fifth Tuesdays of every month by marking them as Monthly nonworking time with 25 occurrences each.
  16. Click the “OK” button when finished.

Applying the Custom Calendar

Complete the following steps to apply the custom calendar as a Task Calendar on each of the Build Review Meeting tasks:

  1. Select the first Build Review Meeting task, then press and hold the “Control” key.
  2. Select the second and third Build Review Meeting tasks.
  3. Release the “Control” key and right-click on any of the selected tasks.
  4. Select the “Information” item on the shortcut menu to open the “Multiple Task Information” dialog.
  5. Click the “Advanced” tab of the dialog.
  6. Click the “Calendar” pick list and select the “Second Tuesday of Each Month” custom calendar.
  7. Click “OK” to apply the custom calendar.

Final Review

Notice how Microsoft Project reschedules all three Build Review Meeting tasks according to the custom calendar. That’s it! You’ve successfully created and applied an unusual calendar to schedule tasks to occur on a particular day of each month. It might not have been obvious at first, but with these steps, you’ve got it mastered.
