I need to create extended calendar which will run on 1st business day of 3rd week of every month.
Mon to Fri are considered as working day and no holiday calendar included.
Sample dates for year 2018 : 16th Jan, 13th Feb, 13th Mar, 17th Apr, 15th May, 12th Jun, 17th Jul, 14th Aug, 11th Sep, 16th Oct, 13th Nov, 11th Dec
Currently I am using standard calendar for this but wants to change it to extended calendar to avoid manual inserts for every year.
