MS Project 2007 Calendar Units No Equal

I have a basic calendar question that is driving me nuts, need some help to understand the logic and make needed corrections for a custom calendar that will provide equal time frame for all time units. The Problem: I'm using the standard MS Project 2007 calendar. When I enter a duration for a task as "365 days" the duration is 6/1/11 to 10/23/12. When I enter a duration as "52 wks" the duration is 6/1/11 to 5/29/12. When I enter a duration as "12 mons" the duration is 6/1/11 to 5/1/12. How can this be? Why is the duration not exactly the same for each entry type?

I know the reason mate, but I don't know how to change it just yet, I'm trying very hard to work it out because our needs in our projects are not so delicate to as be down to the millisecond of when a project has to end.

Anyway the reason is because when you type in 365 days it doesn't 365 work days ie 165 mon-fri which would = ~470 total days.

As for the months the way project unfortunately calculates a month is a month = 4 weeks.

If I find a way to change it in calendar setting without changing the 5 day work week I'll post it on here.
