You need to implement intervalmatch.

LOAD 
     HolidayDate, 
     Holiday_Year, 
     NumOfSatSun
FROM
[https://community.qlik.com/t5/QlikView-App-Development/Logics-in-load-scripts-to-calculate-the-numbers/m-p/1552748#M440397]
(html, codepage is 1252, embedded labels, table is @1);

IntervalMatch(HolidayDate)
LOAD 
     StartDate, 
     EndDate
FROM
[https://community.qlik.com/t5/QlikView-App-Development/Logics-in-load-scripts-to-calculate-the-numbers/m-p/1552748#M440397]
(html, codepage is 1252, embedded labels, table is @2);
