Power Bi Fiscal week column from Week Number

[Anonymous]

I want to build a calendar with below Fiscal WeekNum.

FISCAL WEEK NUMBER

DAX QUERIES used to create calendar table

dimDate =
ADDCOLUMNS (
CALENDAR ("01/04/2019", "31/03/2020"),
"Year", YEAR ( [Date] ),
"WEEK NUMBER",WEEKNUM([Date],2),
"PERIOD","Week " & WEEKNUM([Date],2),
"QuarterOfYear", FORMAT ( [Date], "Q" ),
"MonthNumber", SWITCH(FORMAT ( [Date], "mmm" ),"Jan",10,"Feb",11,"Mar",12,"Apr",1,"May",2,"Jun",3,"Jul",4,"Aug",5,"Sep",6,"Oct",7,"Nov",8,"Dec",9),
"ISODate", FORMAT ( [Date], "DDMMYYYY" ),
"MonthName", FORMAT ( [Date], "mmmm" ),
"MonthInCalendar", FORMAT ( [Date], "mmm YYYY" ),
"QuarterInCalendar", "Q" & FORMAT ( [Date], "Q" ) & " " & FORMAT ( [Date], "YYYY" ),
"DayInWeek", WEEKDAY ( [Date] ),
"DayOfWeekName", FORMAT ( [Date], "dddd" ),
"DayOfWeekShort", FORMAT ( [Date], "ddd" ),
"YearMonthShort", FORMAT ( [Date], "YYYY/mmm" ),
"MonthNameShort", FORMAT ( [Date], "mmm" )
)

Please Note : My Calendar should start "01/04/2019" and end to "31/03/2020".

how about this:

FiscalWeek =
IF (
    'Calendar'[WeekNum] < 40,
    'Calendar'[WeekNum] + 13,
    'Calendar'[WeekNum] - 39
)
