## Comparison between Selected Days and Previous Days

Hi,

I am using a date slicer to select days to show total count of selected period. However, I want to calculate values beyond selected period for the same days selected in Date Slicer.

Basically If I Select 3 days from 27 to 29 May, it should give me the following result in two seperate dax which I will use on card visual:
Current Period = 87 ( 27 to 29 May)

Previous Period = 98 ( 24 to 26 May)

I am using the following dax to calcuate current period.

Current Period =
CALCULATE(
DISTINCTCOUNT(tbl_1 [ID_No]),
DAY(tbl_1[Date] = DAY(TODAY())))

Expected Ouput:

Current Selected Period (days) = [total count]
Previous Period ( days beyond selected days) = [total count]

Any help is really apprecaited. Thank you.

According to my test results, the results of Previous Period are displayed normally. Please point out if I misunderstood.

According to your description, here are my steps you can follow as a solution.

(1) My test data is the same as yours.

(2) We can create measures.

``````Current Period =
CALCULATE(
DISTINCTCOUNT(tbl_1 [ID_No]),
DAY(tbl_1[Date] = DAY(TODAY())))``````
``Previous Period = CALCULATE('Table'[Current Period],FILTER(ALL('Table'),'Table'[Date]=MAX('Table'[Date])-3))``
``Current Selected Period (days) = SUMX(ALLSELECTED('Table'),'Table'[Current Period])``
``Previous Period ( days beyond selected days) = SUMX(ALLSELECTED('Table'),'Table'[Previous Period])``

(3) Then the result is as follows.

If the above one can't help you get the desired result, please provide some sample data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It is better if you can share a simplified pbix file. Thank you.

Hi @v-tangjie-msft

Thank you for your response. It seems like I am getting the partial results results, please see below screenshot.

it is worth to mention that in my table I only have Date & Current period and trying to calculate Previous Period using Dax.

I have used the Dax as:

Previous Period = CALCULATE([Current Period], FILTER(ALL(Table1), Table1[Date] = MAX(Table1[DATE])-3))
Previuos Selected Period = SUMX(ALLSELECTED(Table1), [Previous Period])

It doesn't seem to be a problem in my example file.

Please provide some sample data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It is better if you can share a simplified pbix file. Thank you.
