Revising duration so it doesn't count first day

jim_gagliardi

I want the range of days from Monday the 1st to Monday the 21st to read 21 days; yet it reads "22 days" in the duration column.  This is because day 1 is the first day, when I need "day 1" to be the following date from the first day.  Is there any easy way to fix this?  In my job I can never count the first day as day one as it's against policy in how we count days.

Are you talking about the information in the Duration column? Or a formula that you created yourself?
