Here's two ways to make recurring milestones on the 15th and 30th of each
month. I documented these techniques a year ago. To have it work for a 2hour
task, you may need to play with the Working Hours values for the project.
Method A
1- Insert a Recurring Task and set it as 0days (Milestone), Monthly on the
15th.Set your start and end dates for the three years. Click OK.
2- Expand the list of Milestones. You should have one task per month on the
15th. (Dates will be adjusted away from weekends)
3- Select the first milestone task. Perform a CTL-C, then a CTL-V to copy
and paste the task, creating two copies of the task.
4- Repeat Step-3 to each task so you will have two copies of each Milestone
Task on the 15th of the month.
5- Change the date of each duplicate to the 30th of the month.
6- Adjust the Name of each Task to eliminate the duplicate names.
Now you have Recurring Milestone Tasks twice per month, all under one
Summary. :>)
Method B
1- Create a Recurring Task on the 15th. Name it "Mid-Month"
2- Under these create a Recurring Task on the 30th. Name it "End-Month".
3- The End-Month tasks will be indented under the Mid-Month tasks.
4- Select all the End-Month tasks and outdent them.
5- The End-Month Summary will become a Task. Delete this task.
6- To Sort the tasks: One by one, Click and drag the End-Month Tasks under
their respective Mid-Month task.
7- Rename the Summary Task to "Twice per Month Milestones"
Your done!
