A1:A100 contents dates, B1:B100 values.
How can I sum the values of all Fridays?
 

Excel Facts

Create a chart in one keystroke
Select the data and press Alt+F1 to insert a default chart. You can change the default chart to any chart type
{=SUM((WEEKDAY(A1:A100)=6)*B1:B100)}

Note: This is an array formula which is entered using the Control+Shift+Enter key combination. For more on array formulas see the Excel Help Index topic for "About array formulas and how to enter them".

I have another question yet.
How can I calculate how many Fridays there are in A1:A100?

Use the following array formula
=SUM(IF(WEEKDAY(A1:A100)=6,1,0))

They're really about the same. I used a + operator instead of your IF function call. It's all about the same. You could shorten your IF argument list by omitting the 3rd argument...

{=SUM(IF(WEEKDAY(A1:A100)=6,1))}
