    Hi, nadirS 

    Try to  create calculated column as below:

    Rownumber =
VAR tab =
    FILTER ( ALL ( 'Table' ), 'Table'[Holiday] = 1 )
RETURN
    IF (
        [Holiday] = 1,
        COUNTX ( FILTER ( tab, [Date] <= EARLIER ( 'Table'[Date] ) ), [Holiday] )
    )
    Flag = [Rownumber] + 4
    Result = 
var _enddate=MAXX(ALL('Table'),'Table'[Date])-5
return
IF (
    'Table'[Holiday] = 1 &&'Table'[Date]<=_enddate,
    LOOKUPVALUE ( 'Table'[Date], 'Table'[Rownumber], 'Table'[Flag], [Date] ),
    BLANK()
)
