With having two dates now i month wise days calculation required - excel

I have two dates. Now my aim is to calculate the number of days, month wise for n number of rows
Input:
start date 22/01/2019
finish date 21/06/2019
Output & result should be
January February March April May June
9 28 31 30 31 21
for many rows.
Excel or VBA Excel formula both will be great,
Thanks in advance....
Here is a screenshot of my Excel table:

Here is a simple solution if your Active Month column entries are not the names of the month, but the last day.
31.01.2019 28.02.2019 ...
For the January column you can then use
=MAX(0, MIN($AV14-$AT14, AY$13-$AV14))
and for the other months you have to subtract the days aggregated since January. Here for February:
=MAX(0, MIN($AV14-$AT14, AZ$13-$AV14) - SUM($AY14:AY14))
Expand the last formula from Feb to Dec.

How to get week number based on Two dates based Conditions in Excel

I have a DateTime column in Excel in which data is sorted in ascending order based on DateTime conditions from 15th June to say 1st November ;
I want to print Week Number from 1st to Nth Week based on date condition; Week criteria are like first seven days i.e 15th June to 21st June is Week1, 22nd Jun-28th Jun is Week2, 29th June - 5th June is Week3 and so on.
How Can I do this?
Column1
06/15/2021 8:00
06/15/2021 10:00
:
:
11/01/2021 20:44
11/01/2021 20:46
Let's assume your list of dates is in A2:A.
Place the following formula in cell B2 of an otherwise empty range B2:B...
=ArrayFormula(IF(A2:A="",,ROUNDDOWN((INT(A2:A)-INT(A2))/7)+1))
INT is just removing the times from date-times.
The rest is really more of a math/logic question than a formula question.

How to identify the week within a month with criteria in Excel

How can I calculate the week of the month? I understand that with the WEEKNUM function and ISOWEEKNUM function I can get the week of the year but this is not what I am looking for.
A week has only 4 weeks so the function must look at a date written in a cell and only identify a week 1-4
There is one set of criteria that I found especially difficult to add:
Week 1 for July 2019 begins on June 30th - Ends on July 27th
Week 1 for August begins on July 28th - Ends on August 24th
How can something like this added to an excel function?
This formula calculates a week in month (assuming your have a date at A1 cell)
=WEEKNUM(A1,2)–WEEKNUM(DATE(YEAR(A1),MONTH(A1),1),2)+1
Use WEEKNUM to get the week of year.
Use WEEKNUM to from the date of the first day of the month the date falls within.
Subtract the two week numbers (add 1 in case result is 0 - first week in month).
Sample:
8/21/2019
=WEEKNUM(A1,2) -> 34
WEEKNUM(DATE(YEAR(A1),MONTH(A1),1),2) -> 31
34-31 = 3 -> third week of August

excel date from week number and year

I have the following table in Excel that has year number and week number:
Year Week
----- ------
2015 33
2014 41
2016 40
How can I get a 3rd column that has the date of the corresponding Friday for each row? So, week 33 of 2015 should return: Friday, August 14, 2015.
I have tried to use the date function, weeknum function, but cannot get any consistent results.
If you are using ISO week numbers then this formula will give the date you want
=DATE(A2,1,B2*7+2)-WEEKDAY(DATE(A2,1,3))
where year is in A2 and week number in B2
Format in required date format
With ISO week numbers week 1 always starts on the first Monday on or after 29th December
Assuming the week starts on Sunday and non-ISO week-numbering, the date of the Sunday of Week#1 of any year is given by:
=CHOOSE(WEEKDAY(DATE(A2,1,1)),DATE(A2,1,1),DATE(A2,1,1)-1,DATE(A2,1,1)-2,DATE(A2,1,1)-3,DATE(A2,1,1)-4,DATE(A2,1,1)-5,DATE(A2,1,1)-6)
Then add 5 to move to Friday. Then add:
(B2-1)*7
to advance to the proper week:
=CHOOSE(WEEKDAY(DATE(A2,1,1)),DATE(A2,1,1),DATE(A2,1,1)-1,DATE(A2,1,1)-2,DATE(A2,1,1)-3,DATE(A2,1,1)-4,DATE(A2,1,1)-5,DATE(A2,1,1)-6)+5+(B2-1)*7

How to collect number of days from a month in excel

I have a column which will have some days from a month in dd-mm-yyyy format. What I need to get total number of days from each month mentioned in that column. The column might not contain all days from each month.
Example :
Column A :
2017-01-01
2017-01-02
2017-01-17
2017-01-27
2017-02-08
In above example, from 2017 Jan, I have 4 days and from Feb I have one day. I need this count for a IF statement to run in C column. ie, in C1 there will be an IF function which will check the month in A1 and count the total number of days for that specific month from A column. If that count is below a specific digit, I need to perform a formula otherwise a different one. This will repeat for all C cell
If this column contains all date from each month I can use Day function to get total days, but here how Can I collect it
This will work: =SUMPRODUCT(1*(MONTH($A1:$A5)=D1))
And an example of manipulating basing on the result:
=IF(SUMPRODUCT(1*(MONTH($A1:$A5)=D1))<3;"good";"bad")
Another one when row number represents a month (JAN in C1, FEB in C2...):
=IF(SUMPRODUCT(1*(MONTH($A1:$A5)=ROW()))<3;"good";"bad")
In your case:
=IF(SUMPRODUCT(1*(MONTH($A1:$A5)=ROW()))<10;function1();function2())
Array formula - use Ctrl+Shift+Enter:
=SUM((MONTH($A$1:$A$5)=MONTH(A1))*(YEAR($A$1:$A$5)=YEAR(A1)))

Excel: Sum partial weeks for EOM report

I'm looking for a formula that will let me get a weekly total of a daily totals column during partial weeks at the end month for Excel 2010. Using the US week of Monday-Friday.
I have a Day(A), Date(B), Daily Total(J) and Weekly Total(N) column for one month. I'd like to show the totals for the week (M-F) either on Fridays, or the last day of the month. For full weeks, if the Day="Fri", I can sum column J by using a 5 cell range like $J11-$J15 which would sum the daily totals from Monday thru Friday of a full week in the middle of the month.
That doesn't work for a partial week at the beginning, so I have modified versions for the first 5 days, if a Friday is detected and that seems to work. I'm open to other ideas if there's a better way to handle the first week.
--------------------------------------------------------------------
A B J (N) Week
1 Day Date Total Total Formula for Column N Week Total
2 Thu 1/1/2015 1 =IF($A2="Fri",$J2,"")
3 Fri 1/2/2015 2 3 =IF($A3="Fri",SUM($J$2:$J3),"")
4 =IF($A4="Fri",SUM($J$2:$J4),"")
5 =IF($A5="Fri",SUM($J$2:$J5),"")
6 =IF($A6="Fri",SUM($J$2:$J6),"")
--------------------------------------------------------------------
A6/N6 would be the last possible Friday for the first 5 days of the first week, so the rest of the formulas, until towards the end of the month are similar to:
N7 would be =IF($A7="Fri",SUM($J3:$J7),"")
N8 would be =IF($A8="Fri",SUM($J4:$J8),"")
It handles summing a 5 day full week, in the middle of the month, and only shows the weekly total in column N for Fridays.
I don't know how to handle the last week since it could be a partial week of between 1-4 weekdays, not ending on a Friday. I still want show a total for that last partial week, on the last weekday of the month.
I thought about checking to see if the days in the last week were either Friday or the end of the month, and came up with a check for either "Fri" or the end of the month. For example in January day 31 would be:
(N32) =IF(OR($A32="Fri",EOMONTH($B$2,0)=$B32),SUM($J28:$J32),"")
That works if and only if, the 31st is a Fri, but doesn't work if Jan 31st is a Mon-Thurs since the range to sum is fixed at 5 days ($J28:$J32) and I don't know how to make it variable, based on how many days are in that last week of the month.
I would appreciate your ideas on how to do a monthly report where it can show weekly totals for full or partial weeks. The "plan" is to have 4 empty master workbooks to use for months with 28, 29, 30 and 31 days since I don't know how to make it all purpose and not screw up borders.
Thanks!
Does your data include Saturdays or Sundays? I'm assuming not. If not then you need to check whether the date is the last workday of the month....or a Friday.....and you could just sum everything in column J up to that point and subtract the column N totals form above, i.e. in N2 copied down
=IF(B2="","",IF(OR(A2="Fri",MONTH(WORKDAY(B2,1))<>MONTH(B2)),SUM(J$2:J2)-SUM(N$1:N1),""))
I assume N1 will contain a text header
