To count number of weeks based on slicer

[A_a_a]

Hi All,

I have an option to choose in filters years, months or weeks, depending what users need.

How can I create a measure to count weeks selected? for example if the user selects 'January to March', the measure will show 13 weeks or when the user selects just 2 weeks in week slicer, the measure will show 2, etc.

I have 3 slicers from the same dim date table:

Happy to change the layout if it is better to do the measure, for example:

Please support.

Thank you!

Provide demo file and another DAX for reference:

WkCount = 
VAR _MinYear = MIN('Calendar'[Date].[Year])
VAR _MaxYear = MAX('Calendar'[Date].[Year])
VAR _MinMonth = MIN('Calendar'[Month])
VAR _MaxMonth = MAX('Calendar'[Month])
VAR _MinWeek = MIN('Calendar'[Week])
VAR _MaxWeek = MAX('Calendar'[Week])

RETURN
CALCULATE( DISTINCTCOUNT('Calendar'[Year_Week]), 
FILTER(ALL('Calendar'), 
    'Calendar'[Date].[Year] >= _MinYear && 'Calendar'[Date].[Year] <= _MaxYear &&
    'Calendar'[Month] >= _MinMonth && 'Calendar'[Month] <= _MaxMonth &&
    'Calendar'[Week] >= _MinWeek && 'Calendar'[Week] <= _MaxWeek))

Best Regards,

Joyce

Hi @isjoycewang 

It works 🙂 Thank you!

@A_a_a Convert your Year slicer also as range kind of slicer similar to Month & Week slicers and then use this DAX, it might help:

TotalSelectedWeeks = 
VAR MinSelectedYear = MIN('Date'[Year])
VAR MaxSelectedYear = MAX('Date'[Year])
VAR MinSelectedMonth = MIN('Date'[Month])
VAR MaxSelectedMonth = MAX('Date'[Month])
VAR MinSelectedWeek = MIN('Date'[Week])
VAR MaxSelectedWeek = MAX('Date'[Week])

RETURN
CALCULATE(
    COUNTROWS('Date'),
    ('Date'[Year] >= MinSelectedYear || ISBLANK(MinSelectedYear)) && ('Date'[Year] <= MaxSelectedYear || ISBLANK(MaxSelectedYear)),
    ('Date'[Month] >= MinSelectedMonth || ISBLANK(MinSelectedMonth)) && ('Date'[Month] <= MaxSelectedMonth || ISBLANK(MaxSelectedMonth)),
    ('Date'[Week] >= MinSelectedWeek || ISBLANK(MinSelectedWeek)) && ('Date'[Week] <= MaxSelectedWeek || ISBLANK(MaxSelectedWeek))
)

If you find this insightful, please provide a Kudo and accept this as a solution.

Hi @devesh_gupta 

Thank you for your message.

Not sure why, the number of weeks is incorrect.
