# Excel/Need the correct formula

Question
I'm creating a massive spreadsheet that requires a column to calculate the number of days a person has stayed in a Skilled Unit.  Example:  first cell has a date of 6/1/2015.  Second cell has 6/6/15.  The answer needs to be 6.

I am unable to create the formula for the third column correctly. The resident was IN the unit ON the start date and also the END date.  I keep getting the answer of 5.  I'm sure it's something simple but looking at the Help info hasn't worked.  Your assistance is much appreciated!

say you have one penny  and then later you have six pennies.  How many total pennies - obviously 6.  But if you subtracted the starting number from the total you would get 5.

A1:  6/1/2015
A2:  6/6/2015

I assume you have

A3:  =A2-A1   which produces 5.  But if you want to include the end date, then you need to change the formula to

A3:  =A2-A1+1

Adding one accounts for including the end date.

I even thought of the answer he provided but thought it couldn't (or shouldn't) be calculated in that fashion. Thank you for the opportunity to ask a question and get assistance so quickly. Thanks, Tom!
