How does this Calendar work?
This is the same file as 2011 calendar with the year changed. So,
- The cell D3 in worksheet Full has the year of calendar. I named this cell as year.
- All the formulas for the calendar are written in the worksheet mini.

- For this calendar, I took inspiration from Daniel’s Live Calendar example (Recommended reading for formula enthusiasts).
- The first step to create a calendar is to generate a sequence of numbers 1 thru 42 (because calendar grid has 42 cells – 7 days per week x 6 weeks max, per month). I used a combination of INDIRECT, OFFSET and COLUMN to get this. The formula is
=COLUMN(OFFSET(INDIRECT("$A$1"),0,0,1,42))-1. I mapped this formula todaysAndWksnamed range. - Next step is to find the first date of each month using a simple date formula like
=date(year,month,1). This formula is mapped to named range –DateOfFirst - For given month, the calendar is nothing but
=daysAndWks + DateOfFirst - WEEKDAY(DateOfFirst,2). This formula is mapped to named range –calendar.

- Once the mini calendar is ready, I just created 12 named ranges m1_, m2_,…, m12_ corresponding to each of the 12 months.
- Then, I used the same in individual calendar worksheets along with INDEX formulas to fetch the dates.
- Finally, I formatted the calendars nicely. Design of this calendar is similar to that of 2010 calendar & 2009 calendar templates.
Go ahead and enjoy the download. The file is unlocked. So poke around the formulas and named ranges. Learn some Excel.

Great Chandoo. Keep it up, Looking forward more from BYOD..
Thanks
With Excel 2013 the pivot table could be connected to the data model which provides a distinct count.
This will do for invoice count
=COUNTIF(F:F,H12)
Instead of
=COUNTIFS(sales[SELLER],$H12)
Excellent document. How did you make the last graphic? Witch app. Thanks for answer.
Can someone tell me what =countif(sales[date],sales[date]) is counting? The value is 19. Its found in the =SUMPRODUCT(IF(sales[SELLER]=H12,1/COUNTIFS(sales[SELLER],H12,sales[date],sales[date]),0))
Hi Chris,
=countif(sales [date],sales[date]) function is counting the unique dates in the table.

Excellent document!
Can you explain more about the calculation on Weighted consistency? More specific the small number is 0,00001 ?
How come the number should be smaller if there is more sellers?
Hi,
Not understood this formula: {=SUMPRODUCT(IF(sales[SELLER]=H12,1/COUNTIFS(sales[SELLER],H12,sales[date],sales[date]),0))}
Please explain.
Thanks.
