Counting weeks

I have a task with a start date of June 7 2010 (task 3.4.1.1) (Monday).
I created a milestone with a constraint of 3.4.1.1SS+2w.
The milestone date is June 18 2010 (Friday).

I expected the milestone date to be June 21 (two full weeks after the start of the task).

Why is the milestone scheduled only 7 working days after the start of the task? And more importantly, what do I have to do (in my definitions) so that when I say something starts two weeks after something else, it will be two full weeks?

- The calendar view confirms that I have work scheduled Monday through Friday, a total of 8 weeks per day. (8AM-noon and 1-5 PM)
- All my durations and efforts are equal, so I'm not being fooled by a duration versus effort problem.
- Daily scheduling granularity
- 8 hours work per day (in the project inspector)
- 40 hours work per week (in the project inspector)

"1 week" in OmniPlan means 1 work week, not 1 calendar week. This is the same reason why a task that takes "1 day" means it takes 8 working hours from 8AM to 5PM, not 24 hours.

If you want 1 week to mean 7 days, you have to change the hours per week in the Project : Formatting inspector from 40 hours to 56 hours.

Aaron has told you why the milestone is when it is, but I'm curious about this "only 7 working days" bit -- is that just a mistake in your counting? If the task has a start date of Monday Jun 7, how would Friday Jun 18 be only 7 working days later if you are working 40 hour weeks, 8 hour days with no intervening holidays or vacations?
