Count number of days between a field value and today excluding weekends

[antonjamese]

I need to caclulate the number of days between a table field named Launch_time and today while removing weekends and holidays.

Todays date is not an available field in the table that contains Launch_time.  I keep getting hung up trying to use Today() as a new column because I cannot use it with DATEDIFF or DATESBETWEEN.  I do have a calendar table that contains a field for today's date.

Thanks for the help

Thank you for the responses.

I found the solution on the How To Power BI Youtube page Calculating the Number of Working Days in Power BI | Custom NETWORKDAYS Function using Power Query -....  He has a very good solution that is easy to create and modify.

Hi @antonjamese,

Can you please share a pbix or some dummy data that keep raw data structure with expected results? It should help us clarify your scenario and test to coding formula.

I cannot share the .pbix so I hope this will give you enough information.

I need to calculate the number of days between 'PRODUCT_ORDER_LINEUP'[LAUNCH_TIME] 

and 'FY Calendar'[Today] excluding weekends and holidays, when

'PRODUCT_ORDER_LINEUP' [COMPLETION TIME] is null.

Is Holiday and Is Working Day is in the FY Calendar table

Relationship between FY Calendar and PRODUCT_ORDER_LINEUP

Hi @antonjamese,

Sorry for the late response, you can try to use the following measure formulas to get the selected 'date range' fact table user workday count based current LINE_ID.

Count rows that really recorded in the table:

Measure =
CALCULATE (
    COUNTROWS ( PRODUCT_ORDER_LINEUP ),
    FILTER (
        ALLSELECTED ( PRODUCT_ORDER_LINEUP ),
        [LUNCH_TIME] <= TODAY ()
            && OR ( [COMPLETION TIME] <= TODAY (), [COMPLETION TIME] = BLANK () ) //date range filter
            && WEEKDAY ( [LUNCH_TIME], 2 ) <= 5 //weekend filter
    ),
    VALUES ( PRODUCT_ORDER_LINEUP[LINE_ID] ) //current line_ID filter
)

Workday count of date range except weekends:

Measure =
VAR _startDate =
    CALCULATE (
        MIN ( PRODUCT_ORDER_LINEUP[LUNCH_TIME] ),
        ALLSELECTED ( PRODUCT_ORDER_LINEUP ),
        VALUES ( PRODUCT_ORDER_LINEUP[LINE_ID] )
    )
VAR _endDate =
    CALCULATE (
        MAX ( PRODUCT_ORDER_LINEUP[COMPLETION TIME] ),
        ALLSELECTED ( PRODUCT_ORDER_LINEUP ),
        VALUES ( PRODUCT_ORDER_LINEUP[LINE_ID] )
    )
RETURN
    COUNTROWS (
        FILTER (
            CALENDAR (
                _startDate,
                IF ( _endDate <> BLANK (), MIN ( _endDate, TODAY () ), TODAY () )
            ),
            WEEKDAY ( [LUNCH_TIME], 2 ) <= 5
        )
    )

Thank you for the help.  The count rows measure is working.  The workday count of range is not.  It is failing on line 21.  I have tried several different things but it is still not working. 

The field LUNCH_TIME should be LAUNCH_TIME.

Measure =

VAR _startDate =

CALCULATE (

MIN ( PRODUCT_ORDER_LINEUP[LAUNCH_TIME] ),

ALLSELECTED ( PRODUCT_ORDER_LINEUP ),

VALUES ( PRODUCT_ORDER_LINEUP[LINE_ID] )

)

VAR _endDate =

CALCULATE (

MAX ( PRODUCT_ORDER_LINEUP[COMPLETION_TIME] ),

ALLSELECTED ( PRODUCT_ORDER_LINEUP ),

VALUES ( PRODUCT_ORDER_LINEUP[LINE_ID] )

)

RETURN

COUNTROWS (

FILTER (

CALENDAR (

_startDate,

IF ( _endDate <> BLANK (), MIN ( _endDate, TODAY () ), TODAY () )

),

WEEKDAY ( [LAUNCH_TIME], 2 ) <= this is the line it fails on.

)

)

Hi@antonjamese,

I think the above issue is due to the new calendar table not including the 'LAUNCH _TIME' field, so it can't be used as filter conditions. For this scenario, you can try to use the below formulas that I modified if helps:

Measure =
VAR _startDate =
    CALCULATE (
        MIN ( PRODUCT_ORDER_LINEUP[LUNCH_TIME] ),
        ALLSELECTED ( PRODUCT_ORDER_LINEUP ),
        VALUES ( PRODUCT_ORDER_LINEUP[LINE_ID] )
    )
VAR _endDate =
    CALCULATE (
        MAX ( PRODUCT_ORDER_LINEUP[COMPLETION TIME] ),
        ALLSELECTED ( PRODUCT_ORDER_LINEUP ),
        VALUES ( PRODUCT_ORDER_LINEUP[LINE_ID] )
    )
RETURN
    COUNTROWS (
        FILTER (
            CALENDAR (
                _startDate,
                IF ( _endDate <> BLANK (), MIN ( _endDate, TODAY () ), TODAY () )
            ),
            WEEKDAY ( [Date], 2 ) <= 5
        )
    )

BTW, the above two expressions mean two scenarios to get the workday count. The first one considers the real records in your table; the second one only calculate on the particular date range:

Thanks for your quick response.

I don't seem to be able to get this to work.  I will define it better.

In a table named Product_Order_Lineup I have a field named Launch_Date

In a table named FY Calendar I have a field named Today

In the FY Calendar table I also have the Is Holiday and Is Working day fields

What I need to be able to get is this

Calculate(DatesBetween = ('FY Calendar'[Today], Product_Order_Lineup[Launch_Date] and then exclude my weekends and holidays.

I am getting hung up because the fields I need are in 2 different tables.

Hi ,

You can try something like below : 

Add two flag columns to your Calendar table.

1. Is_Holiday_Flag --- Set to TRUE if holiday, False if not

2. Is_WeekDay_Flag ---- Set to TRUE if WeekDay, False if not

Now, Use the DAX formula as below:

CALCULATE(DATESBETWEEN(Calendar[Date],Calendar[Launch_Date],_MaxDate ),Calendar[Is_Holiday_Flag] = FALSE, Calendar[Is_WeekDay_Flag]=TRUE)

You can replace the _MaxDate  with the field that contains today's date.
