Number of days of week between two date range by month

guilherme88 · Oct 10, 2019

Hello,

I am looking to get the following result:
So basically I need to figure out how many turnaround( airplane comes in gets services and departs with another flight number to different destination) I have between two dates and week days.
For example:
Start End
20MAR20-28MAR20
Days of week
1___4_6_ (Monday, Thursday and Saturday) = 4 days (1monday,1Thursday and 2 Saturdays)

That means, between this period I will have 4 rotations
If my period is 27MAR20-20JUL20 for day _2_____(Tuesday) i know there are 16Tuesdays between these two dates, therefore for that given flight number I will have 16 rotations on Tuesdays for the given period. Now I am trying to figure out by month. Looking at the calendar I know March2020 has 1 Tuesday, April has 4, may has 4, june has 5, and July has 2=TTL16.

That is basically where I am trying to get I have created formulas to break down the days of week and the months in the period, now I need to figure out a way to know how many by month between the periods taking into account the days of the week in that period.

Also if my start date is 11feb20 and my end date is 11feb20 my day of week is D2(tuesday) this should return number 1 as there is only 1 tuesday between these two dates.

Really would appreciate some feeback.

Thank you very much

Guilherme

One last request Nishant

with different years in the dataset. i need to sum it by month and by origin (ABZ,BHX etc...) below a sample of the dataset.
If i want to display by month and year, would need the formula to be arranges in the following way:
OCT19 NOv19 DEC19 Jan20
ABZ 1 4
BHX 2 22 23 23

DATASET

ABZ	______7	27-Oct-19	27-Oct-19
ABZ	___4___	31-Oct-19	26-Mar-20
BHX	12__567	27-Oct-19	28-Mar-20

			0

How can this be achieved?

Thanks again
Guilherme

@Nishant94,

Excellent job.

guilherme88 · Oct 24, 2019

Amazing Nishant Thank you so so much

guilherme88 · Oct 24, 2019

Hi Nishant i have added another if to the formula and came to conclusion it is not reading the data correctly.
I want to cvount only the 00:25 turns so i put an if with the 00:25 in the formula. ABOVE THE COLUMNS corresponding to line 12. Thank you in advance

The formula is: IF([@Ground]=0.0173611111111111,IF(DC$5="","",IF(SUM(--ISNUMBER(MATCH(ROW(INDIRECT((EOMONTH(DC$5,-1)+1)&":"&EOMONTH(DC$5,0))),ROW(INDIRECT($I12&":"&$J12)),0)))>0,SUM(--ISNUMBER(MATCH(WEEKDAY(ROW(INDIRECT(MAX($I12,DC$5)&":"&MIN($J12,EOMONTH(DC$5,0)))),11),(MID(SUBSTITUTE($H12,"_",""),ROW(INDIRECT("1:"&LEN(SUBSTITUTE($H12,"_","")))),1)+0),0))),"")),"") +ctrlshiftenter
