Hi @Niels_IRD ,

 

Please try:

First add an index column:

vjianbolimsft_0-1670230452865.png

Then create a calculated column:

Column =
VAR _a =
    CALCULATE (
        MAX ( 'Table'[Date] ) + MAX ( 'Table'[Time] ),
        FILTER ( 'Table', [Index] = EARLIER ( 'Table'[Index] ) - 1 )
    )
VAR _b = [Date] + [Time]
VAR _c =
    ADDCOLUMNS (
        'Table',
        "a",
            CALCULATE (
                MAX ( 'Table'[Date] ) + MAX ( 'Table'[Time] ),
                FILTER ( 'Table', [Index] = EARLIER ( 'Table'[Index] ) - 1 )
            ),
        "b", [Date] + [Time]
    )
VAR _diff =
    ADDCOLUMNS ( _c, "Diff", DATEDIFF ( [a], [b], MINUTE ) )
VAR _maxindex =
    MINX (
        FILTER ( _diff, [Diff] > 30 && [Index] >= EARLIER ( 'Table'[Index] ) ),
        [Index]
    )
VAR _minindex =
    MAXX (
        FILTER ( _diff, [Diff] > 30 && [Index] <= EARLIER ( 'Table'[Index] ) ),
        [Index]
    ) + 0
VAR _filtertable =
    FILTER ( 'Table', [Index] >= _minindex && [Index] <= _maxindex )
VAR _count =
    COUNTROWS ( FILTER ( _filtertable, [Index] <= EARLIER ( 'Table'[Index] ) ) )
RETURN
    _count

Final output:
