Slicer Help on PowerBi Desktop - Dates

Hi Anonymous ,

I'm very sorry that I did not consider the different years in my previous calculation. Please try the following formula:

SpecialDates = 
var _datetable = DateTable2
var _today = TODAY()
var _month = MONTH(TODAY())
var _year = YEAR(TODAY())
var _thismonthstart = DATE(_year,_month,1)
var _thisyearstart = DATE(_year,1,1)
var _lastmonthstart = EDATE(_thismonthstart,-1)
var _lastmonthend = _thismonthstart-1
var _thisquarterstart = DATE(YEAR(_today),SWITCH(TRUE(),_month>9,10,_month>6,7,_month>3,4,1),1)
var _lastquarterstart = EDATE(_thisquarterstart, -3)
VAR _thisweek = WEEKNUM(TODAY(),2)

return UNION(
    ADDCOLUMNS(FILTER(_datetable,[Date]=_today),"Period","Today","Order",1),
    ADDCOLUMNS(FILTER(_datetable,[Date]=_today-1),"Period","Yesterday","Order",2),
    ADDCOLUMNS(FILTER(_datetable,[Date]>_today-7),"Period","Last 7 Days","Order",3),
    ADDCOLUMNS(FILTER(_datetable,[Date]>=_thismonthstart),"Period","This Month","Order",4),
    ADDCOLUMNS(FILTER(_datetable,[Date]>=_lastmonthstart && [Date]<_thismonthstart),"Period","Last Month","Order",5),
    ADDCOLUMNS(FILTER(_datetable,[Date]>=_thisquarterstart),"Period","This Quarter","Order",6),
    ADDCOLUMNS(FILTER(_datetable,[Date]>=_lastquarterstart && [Date]<_thisquarterstart),"Period","Last Quarter","Order",7),
    ADDCOLUMNS(FILTER(_datetable,[Date]>=_thisyearstart),"Period","This Year","Order",8),
    ADDCOLUMNS(FILTER(_datetable,[Date]>_today-30),"Period","Last 30 Days","Order",9),
    ADDCOLUMNS(FILTER(_datetable,[Date]>_today-60),"Period","Last 60 Days","Order",10),
    ADDCOLUMNS(FILTER(_datetable,[Date]>_today-90),"Period","Last 90 Days","Order",11),
    ADDCOLUMNS(FILTER(_datetable,[Date]>_today-120),"Period","Last 120 Days","Order",12),
    ADDCOLUMNS(FILTER(_datetable,WEEKNUM([Date],2)=_thisweek && YEAR([Date])=_year),"Period","This Week","Order",13),
    ADDCOLUMNS(FILTER(_datetable,WEEKNUM([Date],2)=_thisweek-1 && YEAR([Date])=_year),"Period","Last Week","Order",14)
)

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.
