How to update Project Calendar & Keep Start / Finish Dates the same
It kinda sounds like you want to do the schedule instead of letting Project do what it does best. Hopefully you are NOT also using manual scheduling. If you are then why use Project, Excel would be easier.
But to answer your question, how did you enter the duration values, hours or days? If your 7 day workweek calendar still has the default 8 hour workday (8:00 AM to 5:00 PM with 1 hour lunch break), then adding the 2 extra days will effectively add 2 days or 16 hours which you will have to add to each duration value. If you have custom work hours in your 7 day calendar, then you will have to add the appropriate amount.
You will have to do all this manually, there is no setting that will automatically make the adjustment for you.
Hope this helps.

- The duration values are days. Most of these tasks are already complete, this schedule includes a lot of retroactive tasks I've added to represent projects that have already been completed. The dates are correct, except It would be nice to be able to see the true durations. I don't see why if task is set to 100% complete and then update the calendar for said activity, then it should update the duration, but instead it doesn't do anything. Or the ability to constrain all said task start / finish dates then update calendar which would then only have one option but to alter durations.
- Oilschedule,
Here's the why. You can't change history. When a task is done, it's done.
But here's something you can try. First, re-set the Project calendar to the 7 day workweek. Second, zero out the Percent Complete field. Third, update the duration by 2 days. The start and finish dates should remain the same. Finally, enter 100% into the Duration field.
If resources are assigned to the tasks, the above process needs to be modified or you'll end up with some incorrect data.
