Hi @Anonymous ,

You can create a Calendar table in Power BI using your START DATE and END DATE. Something like below:

CALENDAR(DATE(2021, 1, 1), DATE(2021, 6, 1))

You can check more details here: https://docs.microsoft.com/en-us/dax/calendar-function-dax

Thanks,

Hi @Pragati11, I already have a calendar/date table. I want to see how many days an employee has worked, by checking the distinct dates that occur in the source file until today.

Let's say this is the data.

Name	Date
X	26-6-2021
Y	27-6-2021
Z	29-6-2021
X	20-7-2021
Y	23-7-2021
Z	24-7-2021

I want to count the the number of unique dates for X, Y or Z from the first available date until today.

Hi @Anonymous ,

Try the following formula:

Measure = 
COUNTROWS(
    DATESBETWEEN(
        'calendar'[Date],
        MIN('Table'[Date]),
        TODAY()
    )
)

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.

Hi @Anonymous ,

Counting unique dates against a name is easy as shown below:

As you haven't attached the expected output along with the input, I will ask again what do you mean by - from the first available date until today ?

Thanks,
