Hi, @raymond 

Based on my research, you may create a measure as below.

CountDays = 
var _maxdate = 
CALCULATE(
    MAX('Table'[Date]),
    ALLSELECTED('Table')
)

var _maxvalue = 
LOOKUPVALUE(
    'Table'[Value],
    'Table'[Date],
    _maxdate
)

var _halfvaluedate = 
LOOKUPVALUE(
    'Table'[Date],
    'Table'[Value],
    CALCULATE(
        MAX('Table'[Value]),
        FILTER(
            ALLSELECTED('Table'),
            'Table'[Value]<=_maxvalue/2
        )
    )
)

return
DATEDIFF(
    _halfvaluedate,
    _maxdate,
    DAY
)+1

Result:

The information you have provided is not making the problem clear to me. Can you please explain with an example.

Appreciate your Kudos.

It should work a little like this. Depending on the date selection one makes, the measure should calculate the number of days that are between the largest value (here accumulated) and half of the value.
