    Create Fiscal weeks over 3 years of data

    Sorry if this has been asked elsewhere, but I cant find a solution to my specific requirements.

    My Fiscal Year starts on the 1st Feb, and I'm trying to make the Week Number start at 1 for the 1st of Feb but become week 2 on the first Monday thereafter.

    I'm comparing figures across 3 years, so in 2016 week 1 was fine as it was a Monday, but 2017 week 1 would start on Wed 1st Feb, Week 2 would start on Mon 6th Feb, and in 2018 week 1 starts Thur 1st Feb, but week 2 starts on Mon 5th.

    Is there any way for to have excel 2010 create this fiscal week in a single data set from 01 Feb 2016 to present?

    Thanks in advance

    Are you wanting every date over three years mapped, or a formula that can simply work out the week number for any date in the range?

    Re: Create Fiscal weeks over 3 years of data

    This is a data set that is being imported daily basis, I already have a fiscal year formula starting on the 1st Feb each year, so I would like the Fiscal Week to reset back to 1 on the 1st Monday in Feb each Year.

    Hope this makes sense.

    Yes, it does, so give us the formula you are using and we can show you how to adapt it.

    My Fiscal Year Formula is as follows...

    =YEAR(B2)+(MONTH(B2)>=2)-1



    I just cant figure out how to make this week based.

    So do you want the counting to restart on 01 Feb, or on the first Moday in Feb?

    Can you work with or adapt this?

    =IF(MONTH(B2)>1,ISOWEEKNUM(B2)-4,ISOWEEKNUM(B2)+48)

    I had seen this function, but unfortunately I'm working with Excel 2010 and the ISOWEEKNUM only started in 2013...

    I have also found this formula and it seems to work, but somewhere it seems to be referencing the 1st October as the start of the financial year. (had to paste as image as I couldnt cut and paste due to html error??

    Re: Create Fiscal weeks over 3 years of data

    Hello Yameye and Welcome to Excel Forum.
    To me it looks as if the formula is referencing April 1st, as the arguments for DATE are (year, month, day). You might get your desired result by changing the DATE(YEAR(B2),4,1) to DATE(YEAR(B2),2,1) throughout the formula.
    If that doesn't work perhaps you could upload a small, desensitized, sample of your spreadsheet by clicking on GO ADVANCED button below the Quick Reply window and then scrolling down to Manage Attachments to open the upload window.
    I imagine that the html error you encountered was due to the portion of the formula ...B2< followed immediately by IF. Put a space between any < symbol and the next letter/number as in B2< IF before submitting the formula as a part of your message.
    Let us know if you have any questions.
