    Question Calculate number of days in a particular month/year between two dates

    Hi All

    I am trying to identify a formula that will allow me to identify how many rental days occured between two dates in a particular month for a report I have to produce each month.

    The report shows cars out on rent which in some case have been out for over 12 months and I need to be able to calculate how many rental days have occured for each booking in the relevant reporting month. I am currently doing this manually by manipulating data but want to try and find an automated way so I can write a macro!

    I have attached an example of the type of data I am presented with:

    Thanks in advance

    In E2 put 30/04/11 The last date for April.

    In d2 put =IF(MONTH(B2)=4,$E$2-B2,"") and format to Number 2 decimal places then copy down.

    Unfortunately that does not appear to provide the result i'm after. It should return a figure of 30 in D2 but is blank?

    Sorry I thought you were just interested In May End and Date Times.

    Put 01/04/11 In E1
    Put 30/04/11 In E2
    Put =MONTH(E2 In E3)

    Put this in D2 and copy it down

    =IF(MONTH(B2)=$E$3,$E$2-B2,IF(MONTH(B2)>$E$3,$E$2-$E$1+1))

    Sorry this does not appear to be working either, it returns a result in D2 of 40635??

    Have you formatted the cells to Number with 2 Decimal places?

    Re: Calculate number of days in a particular month/year between two dates

    Hi Timbo, apologies I put a date in the wrong place which caused the formula to fail.

    I have correct my error however it appears that whilst it is working for some it does not work correctly for any rental that finished in April. An example is cell D6, it returns a result of 5.54 days however it should return a result of 24 days?

    I have uploaded the spreadsheet again just in case i'm being a muppet. :-)

    No me being a muppet, one of those days!

    Try this in D2

    =IF(MONTH(B2)>$E$3,$E$2-$E$1+1,IF(MONTH(B2)=$E$3,B2-$E$1+1))

    Hi Timbo

    No worries, I know the feeling! really appreciate you taking the time to help me.

    Ok have input the new formula and it appears we are nearly there however (sorry) in cell D22 it is returning a result of 30 days but the rental only started in April so should only return a result of 15 days?

    Re: Calculate number of days in a particular month/year between two dates

    Try this formula in D2 copied down

    =MAX(0,MIN(B2,E$2+1)-MAX(A2,E$1))

    That takes the times into account as well so it will give you fractional days, is that what you want?

    Re: Calculate number of days in a particular month/year between two dates

    Excellent, many thanks both for all your help.

    Not wishing to take the "P" but we provide our customers with a 59 minute grace period in any rental therefore in order for me to make this report 100% accurate I need to try and factor this in, would this be possible?

    An example would be as follows:

    Rental starts 01/04/2011 09.00 and finishes 02/04/2011 10.00. We would see that as 2 days.

    Re: Calculate number of days in a particular month/year between two dates

    Perhaps subtract an hour and then round up - that would give you an integer, e.g. 1 day 12 hours would round to 2 days...so would 2 days 59 minutes.....but 2 days 1 hour 10 mins would round to 3 days.

    To do that with my suggested formula change to

    =CEILING(MAX(0,MIN(B2,E$2+1)-MAX(A2,E$1)-"1:00"),1)

    Re: Calculate number of days in a particular month/year between two dates

    Used the formula on my report and whilst there is the odd one where i'm a day out (i.e D23 should be 9 days but shows 10) it gets me 99% of the way there and I think I can run with that. Unless of course you can think of a way to eliminate these errors?

    Thank you very much for all your help, much appreciated.
