# How to count the number of days in a column.

All,

I have sheet that I need to count the number of days in a column. The first cell stays the same (D20) but the column gets bigger or smaller on any given day. I need to fill in how many day between today and the rest of the days in the column.  If you look at my sheet you will see what I need.

Thanks for the help!

in the date column I need to count from todays date to the dates in the column. (excluding weekends and holidays in the formula)
For Example

4-8, 4-7, 4-4   in the box 1 to 2 days   I would put 3  (meaning 3 dates are 1 to 2 days from today)

4-1, 4-2, 4-3   in the box 3 to 5 days I would put 3   and so on for the rest of the boxes up top.

I think I found the formula - I need to use NETWORKDAYS  but since the column changes daily.... how do I get it to work? Also I need to exclude weekends and holidays.

Sorry for the delay.

You need to setup a helper column to count the days using the following formula (and drag down):
``````=IF(D20>TODAY(),NETWORKDAYS(TODAY(),D20),NETWORKDAYS(D20,TODAY()))
``````

To count the number of occurrences of 0-2 use this formula:
``````=COUNTIF(\$F\$20:\$F\$35,"<=2")
``````

To count the number of occurrences of 3-5 use this formula:
``````=COUNTIFS(F20:F35,">2",F20:F35,"<6")
``````

To count the number of occurrences of 6-10 use this formula:
``````=COUNTIFS(\$F\$20:\$F\$35,">5",\$F\$20:\$F\$35,"<11")
``````

To count the number of occurrences of larger than 11 use this formula:
``````=COUNTIF(\$F\$20:\$F\$35,">=11")
``````

This formula will give you the average:
``````=AVERAGE(F20:F35)
``````

Thanks for all the formulas. Will the formulas work if my column size changes daily. My data may only go from F20 to F25 or it may be more like F20 to F40.... how do I make this dynamic?

There are several methods to create dynamic named ranges, you will probably get a larger variety of answers if you post a new question. If you do want I can show you several methods.

I did mention about the dynamics of the columns in this question I did not say dynamic but that's what I meant.

"I have sheet that I need to count the number of days in a column. The first cell stays the same (D20) but the column gets bigger or smaller on any given day. "

You don't have to open a new question, but since there are many methods, chances are you will get more responses from other experts on a new question.

Anyway, the most simple method of all is to create a table (select the data then click Table on the Add tab), then in-place of the range put the table column name i.e.
``````=COUNTIF(Table1[helper column],"<=2")
=COUNTIFS(Table1[helper column],">2",Table1[helper column],"<6")
=COUNTIFS(Table1[helper column],">5",Table1[helper column],"<11")
=COUNTIF(Table1[helper column],">=11")
``````

Unfortunately, I cannot change the sheet I am working with. I can add the formulas but cannot modify it that way. I can open another question using these formulas. Thanks for the help!
