In the example below we want to sum up the total sales for “John” in quarter 2 (Q2). i.e. our criteria is “John” in column B and “Q2″ in column C. We will use the following formula for this purpose:

=SUM(IF($B$2:$B$17=”John”,IF($C$2:$C$17=”Q2″,$D$2:$D$17,0),0))

However this formula should be an “Array formula”. To make it an “Array formula” you should press CTRL+SHIFT+ENTER while you are in the edit mode of the formula. It should then look like this :

{=SUM(IF($B$2:$B$17=”John”,IF($C$2:$C$17=”Q2″,$D$2:$D$17,0),0))}

This formula will give us a result of 9547 (summing sales in the yellow rows).

Note:

The formula presented in this post is generated using the conditional sum wizard. You can try the wizard for yourself.

If you have the Analysis Toolpak installed, then the wizard should be available in the Tools menu. If not then read more on: How-to-install-and-load-the-analysis-toolpak.

1. Both dates occur in the same year.
2. Dates occur in two different years.

Case 1 - both dates occur in the same year

Use the MONTH function to extract the month from each date, then subtract the two months from each other.

Example (using format:dd/mm/yyyy):

Suppose you have the date 25/09/2007 in cell A1 and the date 31/12/2007 in cell B1 (both cells formatted as date). To calculate the number of months between these two dates you use the following formula:

=MONTH(B1) - MONTH(A1)

This should give a result of 3.

Note that the cell where you write the formula must be formatted as number and not date.

Case 2 - dates occur in two different years

Use the the YEAR function and the MONTH function.

Example (using format:dd/mm/yyyy):

Suppose you have the date 25/09/2007 in cell A1 and the date 31/03/2008 in cell B1 (both cells formatted as date). To calculate the number of months between these two dates you use the following formula:

=(YEAR(B1)-YEAR(A1))*12+MONTH(B1)-MONTH(A1)

This should give a result of 6.

Again the cell where you write the formula must be formatted as number and not date.

Example (using format:dd/mm/yyyy):

Suppose you have the date 25/11/2007 in cell A1 and the date 15/01/2008 in cell B1 (both cells formatted as date). To calculate the difference between these two dates you use the following formula:

=B1 - A1

This should give a result of 51 ( 5 days in Nov + 31 in Dec + 15 in Jan).

Note that the cell where you write the formula must be formatted as number and not date.

SUMIF(range,criteria,sum_range)

Range is the range of cells that you want to be evaluated using the specified criteria.

Criteria is the criteria in the form of a number, expression, or text that defines which cells will be added or summed.

Sum_range are the actual cells to add if their corresponding cells in the range match criteria.

In the following example if we want to sum all the sales for Product3 then we will use the following formula:

=SUMIF(A2:A13;”Product3″;C2:C13)

I.e. we will search for “Product3″ in the range A2:A13. When it is found then the corresponding value (in the same row) from the range C2:C13 will be added to the sum. 

This will give a result of 465 (77 + 200 + 188).

The best way to explain how to create a subtotal is by using an example.

In the image below you see a list of products, salesmen and total sales for a product / salesman.

To create subtotals of the “Total Sales” by product, you perform the following steps:

1. Prepare your data table, make sure you have columns headings and sort the data by your key or category (Product in our example).

2. Select the data range or simply click on a cell within the range.

3. In the Data menu click Subtotals. The Subtotal dialogue will open.

4. From the combo box labeled “At each change in:” select the category on which you want to base the subtotals.

5. From the combo box labeled “Use function:” select the function to be used in calculating the subtotals. Usually you will use the SUM function, but in some cases you may just want to know “how many items” so you will use the COUNT function instead.

6. From the list labeled “Add subtotal to:” select the column to be summarized into subtotals.

7. Click OK.

8. The new list of your data will look like this.

9. When the subtotals are created, Excel also defines groups based on the rows used to calculate the subtotals. The groupings form an outline of your worksheet based on the criteria that you used to create the subtotals.

At the top left corner of the image above you will see the numbers 1 2 3. This is the outline of your subtotals.

• Click on 3 and you will get all details of your data.
• Click on 2 and you will only get the subtotals by category.
• Click on 1 and you will only get the grand total.

This is what you get when you click “2″.

Note:

To remove subtotals:

1. In the Data menu click Subtotals.

2. When the Subtotal dialogue opens, click the button labeled “Remove All”.

Names of days and months

I have put the names of days and months as tables in the “Settings” worksheet. This will allow you to translate them in your own language if necessary. You have to unprotect the sheet first before you can do that.

Protection

1. All sheets are protected to avoid accidental change of data and formulas. If you want to make some changes like formatting for example, then you can unprotect the sheet. Make sure however that you don’t mess up the formulas.
2. Columns X and Y are hidden but not protected. These columns receive data from the two combo boxes for the year and the start date.

Printing

You can print the calendar just like any other Excel worksheet. The print area is set in a way that it will only print the year and the 12 boxes for the months, i.e. without the combo boxes.

VBA code

If you want to see the code behind all this, then switch to visual basic editor. The main routines are in module2, but some of the code is within different events of the workbook and the combo boxes.

Your feedback is appreciated.

Syntax

WEEKNUM(serial_num,return_type)

serial_num : is a valid date. E.g. August 15, 2008 or 12/10/2008.

Return_type : is a number that determines on which day the week begins. (1 = Sunday, 2 = Monday). The default is 1.

Example:

If cell A1 = 10/19/2008 , which is a Sunday, then:

=WEEKNUM(A1,1) will return a week number of 43 (week begins in Sunday).

=WEEKNUM(A1,2) will return a week number of 42 (week begins in Monday).

Note:

WEEKNUM function is part of the Analysis ToolPak add-in. If it is not available in your list of functions then you have to install the Analysis ToolPak. Check the following link for more help:

install and load the Analysis ToolPak add-in

Important note (from Microsoft Excel Help)

The WEEKNUM function considers the week containing January 1 to be the first week of the year. However, there is a European standard that defines the first week as the one with the majority of days (four or more) falling in the new year. This means that for years in which there are three days or less in the first week of January, the WEEKNUM function returns week numbers that are incorrect according to the European standard.

But what if we want to count cells that meet multiple criteria. We can not use the COUNTIF function  in this case, so we will take a different approach and use the SUM function.

In the example below we want to count how often “John” appeared in the list in quarter 2 (Q2). i.e. our critera is “John” in column B and “Q2″ in column C. We will use the following formula for this purpose:

=SUM((B1:B17=”John”)*(C1:C17=”Q2″))

However this formula should be an “Array formula”. To make it an “Array formula” you should press CTRL+SHIFT+ENTER while you are in the edit mode of the formula. It should then look like this :

{=SUM((B1:B17=”John”)*(C1:C17=”Q2″))}

This formula will give us a result of 3 as you can see.

Because this function count cells based on a given criteria, that fact will help us limit the count to our specified value.

If in the example below we want to count how often “John” appeared in the list, then we will use the following formula:

=COUNTIF(B1:B15;”John”)

This will give us a result of 7 as you can see.

Pivot table is a feature of Excel that takes a long list of data, summarizes it into a shorter list that is more easy to analyze and assimilate.

The best way to explain how to create a pivot table is by using an example.

In the image below you see a list of products, salesmen and total sales for a product / salesman.

To create a pivot to summarize the total sales by product, you perform the following steps:

1. Prepare your data table and make sure you have columns headings.

2. Select the data range or simply click on a cell within the range.

3. In the data menu click Pivot Table and then follow the wizard.

4. When you get the pivot table field list:

1. Drop the “Product” field in the area where its says “Drop row fields here”.
2. Drop the “Total Sales” field in the area where its says “Drop data items here”. You will get the pivot table as shown here:

5. You can then plot a chart using the pivot table instead of your detailed data.

Perform the following steps to achieve this goal:

1. First make sure that your column has a header row.

2. Select your data range (including the header row).

3. On the Data menu point to Filter, then click Advanced Filter. The Advanced Filter window will open.

4. Click Copy to another location.

5. The List range text box should have your data range. If not then click on it, go to your worksheet and select the range.

6. Click on the Copy to text box. Go to your sheet and click on a blank column (or just a single cell) where you want your unique vales to be copied.

7. Select the Unique records only check box and click OK.

8. To count the unique values just copied, use the COUNTA function or the ROWS function. E.g if the unique values are in the range E1:E6 then in a separate cell enter one of the following formulas:

1. “=COUNTA(E2:E6)”

2. “=ROWS(E2:E6)”
