Answer: calculating number of weeks between two dates
 
Hi there!

You can use the
Code:

DATEDIF
function in Excel to calculate the number of weeks between two dates. Here's how you can do it:
  1. In the third column (duration), select the cell where you want to display the number of weeks.
  2. Type the following formula:
    Code:

    =DATEDIF(A2,B2,"w")
    - A2 is the cell containing the start date
    - B2 is the cell containing the end date
    - "w" tells Excel to calculate the number of weeks between the two dates
  3. Press Enter to calculate the number of weeks.

That's it! The duration column will now display the number of weeks between the start and end dates. Keep in mind that the
Code:

DATEDIF
function only works with dates in the same year, so if your start and end dates are in different years, you'll need to use a different formula. Let me know if you have any other questions!

Hey there,

First make sure these cells are formatted as dates (and not text)
Ensure you have the ATP (go to tools, add-ins and check the box next to
Analysis Toolpak)
Then use the NETWORKDAYS function (formula)
for instance
col A = start date
col B = end date
col C = duration (in working days)
(opt) col D = could be the number of weeks or any other calculation


For example, col C will be your formula...
If A1 = 3/16/07
If B1 = 4/2/07
C1 will need the following pasted into it:

=NETWORKDAYS(A1,B1)

This formula calculates the number of working days between 2 dates.
Your result here should be 12

You could then do a SUM function in the next column to divide the network
days to give you an approx week calculation

Hope it helps!

To show the weeks in my 3rd column, I used:
=(networkdays(A1,B1))/5
and it seems to work. Is this an accurate way to modify the formula to show
weeks?

Thanks!

If start date is column A and end date is in column B and both are formated
as dates, then for row 2 the calculation would be =(B2-A2)/7.
For this data:
Start Date End Date Weeks
3/12/2007 4/14/2007 4.7143
The result if formatted as number with 4 decimal places, so you can see it's
almost 4 1/2 weeks. If you just want it to round to the nearest number of
weeks, set the decimals to zero (which in this case would round to 5). If
you want to show full weeks only enter the formula:
=INT((B3-A3)/7)
which would return an answer of 4.
