Sorry for the confusion. Like I said I am new to the program.
The type of schedule I have created is one for a construction project. I
have a task that is specific for a phase of the project such as the
"construction phase". The period of time I have entered is a start date of
3/9/09 and a finish date of 3/9/10. The value I am getting for the duration
is 262 days. I want it to read 365 days. I hope this helps.
261 working days is one year. Durations in Project do not count non-working
days. I'm guessing you haven't entered your holidays into your calendar
under "Tools, Change Working Time" or your duration would be less by the
number of holidays.
Bigger problem. Project doesn't work very well when you specify both Start
and Finish dates. In fact, you can't in the "Project, Project Information"
dialog box. So my first question is, where did you enter both a project
Start and a project Finish date?
Better to enter a project Start date. Then enter the list of tasks required
to accomplish the project, their duration estimates, and the links between
them. Make sure all the links are there and correct, and that no false
links are inserted, by you or by Project. Project will then tell you how
long it takes to do your Project. It may not be what you like, most likely
not a year. But it will be the best estimate you have at this point of how
long it will really take. One of it's primary functions is to dispel our
illusions and get us off de Nile.
To avoid Project creating false links, go to "Tools, options" and select
the "Schedule" tab. Near the bottom, turn off "Auto link inserted or moved
tasks". Now Project probably won't sabotage your best efforts at a
meaningful schedule.
If the resultant schedule is much more than a year (261 days duration), you
should google this NG for information on Attacking the Critical Path. Might
want to look up a bit about the Critical Path first.
Project is not entirely intuitive. Scheduling is a discipline, one not
learned overnight. If you want to get the full benefit of using scheduling
software, you'll need to invest some time. If you're too busy to do so, my
advice is to use Excel for your scheduling instead. Much simpler,
straightforward and intuitive and will conform to just about any system you
devise. Project won't.
Hope this helps in your world.
