I am trying to set up a plan with units of months over a four year period. When I create a task and give it a duration of 48 mo starting at 'T', it is shown on the Gantt chart as lasting for about 3 years and 9 months, and in the task inspector as having a duration of 191w and 4d. If I manually stretch the task bar until it reaches the 4 year mark, it is shown as having a duration of 52 months!

I guess that I need to do something with the calendar or with the effort conversion factors, but what? Since I am only planning in months, I don't care about the time or length of the working week, or anything like that.
