If you have a task that will happen every couple of days or every month — any regular schedule, really — Project can help you create it as a recurring task, so you only have to set it up once.

Note:  If you have a repeating task that isn’t on a regular schedule, you need to create a separate task for each occurrence.

Create a recurring task

  1. Click View > Gantt Chart.

  2. Select the row below where you want the recurring task to appear.

  3. Click Task, click the bottom part of the Task button and then click Recurring Task.

  4. In the Task Name box, type the recurring task’s name.

  5. In the Duration box, add the duration of each occurrence of the task.

  6. In the Recurrence pattern section, click Daily, Weekly, Monthly, or Yearly.

    You can fine-tune how often the task repeats in the area to the right of these options. For example, you can create a task that repeats every Tuesday and Thursday, or one that repeats every three weeks.

  7. In the Start box, add a start date and then decide when the repeating task will end:

    • Pick End after, and then type the number of times the task will repeat.

    • Pick End by, and then enter the date you want the recurring task to end.

  8. Pick an item from the Calendar list, but only if you want the recurring task to have a different calendar than the rest of the project.

    For example, the recurring task could happen during the night shift, while the rest of the project happens during daytime business hours.

  9. Check Scheduling ignores resource calendars if you want Project to schedule the recurring task even if it does not happen when any resources are available to work on it.
