How do I filter rows by date range in DAX?

What do I need to add to the DAX scripts below to include only rows with dates that fall in the period January 1, 2013 to December 31, 2018?
 
For the first two scripts, there is only one table. It is called 'Data'.
For the last script, there are two tables. They are called 'Data' and 'Standards'.
For all three scripts, the date data is in column 'Date' in table 'Data'
 
Thx in advance
 
res ct dist =
  CALCULATE(
    COUNTROWS('Data'),
      FILTER(
        ALLEXCEPT('Data','Data'[Parameter]),[Sample Type]="DISTRIBUTION"))
 
det ct dist =
  CALCULATE(COUNTROWS('Data'),
    FILTER(ALLEXCEPT('Data','Data'[Parameter]),[Result - Numeric]<>BLANK()),
    FILTER('Data',[Sample Type]="DISTRIBUTION"))
 
Std/2 dist =
  IF(
    NOT(
      ISBLANK(
        CALCULATE(
          SELECTEDVALUE(Standards[Standard]),
          CROSSFILTER(Data[Parameter],Standards[Parameter],BOTH)))),
            CALCULATE(COUNTROWS(Data),
            FILTER(Data,Data[Result-Numeric-in ug/L]>=DIVIDE(RELATED(Standards[Standard]),2,-999)),
            FILTER(Data,Data[Sample Type]="DISTRIBUTION")))

    Hi pmcinnis ,

    try this:

    res ct dist =
CALCULATE (
    COUNTROWS ( 'Data' ),
    FILTER (
        ALLEXCEPT ( 'Data', 'Data'[Parameter] ),
        [Sample Type] = "DISTRIBUTION"
            && Data[Date] >= DATE ( 2018, 1, 1 )
            && Data[Date] <= DATE ( 2018, 12, 31 )
    )
)

     

    Cheers,
    Sturla
