Hi  S3 ,

I created some data:

HolidayTable:

Table:

You might consider using List Slicer.
Here are the steps you can follow：

1. Create measure.

Flag =
var _select=SELECTEDVALUE('HolidayTable'[Holidays])
var _selectstart=MAXX(FILTER(ALL(HolidayTable),'HolidayTable'[Holidays]=_select),[StartDate])
var _selectEnd=MAXX(FILTER(ALL(HolidayTable),'HolidayTable'[Holidays]=_select),[EndDate])
return
IF(
   MAX('Table'[Date])>=_selectstart&&
  MAX('Table'[Date])<=_selectEnd,1,0)

2. Place [Flag]in Filters, set is=1, apply filter.

3. Result:
