Re: Duration calculation

What time does the task start on 7/21? What time does it end on 8/25? (Go to the Tools/Options menu, the View tab, and select a date format that displays the time as well as the date).

Remember that duration is always measured in minutes and fractions of a day at either end can make the real duration slightly off from the number you get counting dates on a calendar. For example, with a normal 8 hour workday with working time of 8am to 5pm, a task that begins at 1pm on Monday and finishes at noon on Wednesday has a 2 day duration, not 3 days as you might expect if you simply looked at the dates - starting Mon and ending Wed - and ignored the times. Each 8 hour interval is a day. Monday afternoon is 1/2 day, Tuesday is 1 full day, and Wednesday morning is the final half day, giving from Monday apparently through Wednesday a total duration of 2 8-hour days.

I checked to see if there were any non-working days in the change working
time and there were not. Still confused about it.

Hello Trevor,

Well obviously, I was not thinking straight or something. Either too
much coffee or not enough. When I create a task with a start date of
July 21, 2007 at 8:00 am and enter a 35 day duration, I show August 24,
2007 at 5:00 pm as the finish date. A duration of 36 days gives me
August 25, 2007. Is it possible you have one nonworking day in between
those dates?

Sorry for any ealier confusion.

I hope this helps. Let us know how you get along.
