Date Add Interval Calculation in Power Query

[Mubar22]

Hi,

I want to create a condition column in Power Query that will calculate a new datetime with duration for me based on the date I specified in the condition. please check the SQL CASE when attached I wrote.

CASE  
            WHEN EXTRACT(HOUR FROM assigned_date) >= 8 AND EXTRACT(HOUR FROM assigned_date) < 16
            THEN TIMESTAMP_TRUNC(TIMESTAMP(DATE(assigned_date)) + INTERVAL 1 DAY + INTERVAL 7 HOUR, HOUR)

            WHEN EXTRACT(HOUR FROM assigned_date) >= 16 AND EXTRACT(HOUR FROM assigned_date) < 24
            THEN TIMESTAMP_TRUNC(TIMESTAMP(DATE(assigned_date)) + INTERVAL 1 DAY + INTERVAL 13 HOUR, HOUR)

            WHEN EXTRACT(HOUR FROM assigned_date) >= 0 AND EXTRACT(HOUR FROM assigned_date) < 8
            THEN TIMESTAMP_TRUNC(TIMESTAMP(DATE(assigned_date)) + INTERVAL 13 HOUR, HOUR)
            
        END AS outbound_compliance_date,

What this does is to calcalute a new date when the assigned_date is between 8am and 4pm then it should return a column byu adding 1 day and 7hrs to the assigned_date (i.e 6/11/2024 07:45AM output: 6/12/2024 07:00AM)

Thanks.

    Date.From(assigned_date) & #time(0, 0, 0) + 
        #duration(
            Number.From(Number.IntegerDivide(Time.Hour(Time.From(assigned_date)), 8 ) > 0), 
            13 - 6 * Number.From(Number.IntegerDivide(Time.Hour(Time.From(assigned_date)), 8 ) = 1), 
            0, 0
        )

Hi @AlienSx 

Please can you give more context on how this works. Thanks

let
    Source = #table(
        {"assigned_date"}, 
        {{#datetime(2024, 06, 11, 7, 45, 0)},
        {#datetime(2024, 06, 11, 11, 30, 0)},
        {#datetime(2024, 06, 11, 22, 15, 0)}}
    ), 
    compliance_date = Table.AddColumn(
        Source, 
        "outbound_compliance_date",
        each 
            [check_time = Number.IntegerDivide(Time.Hour(Time.From([assigned_date])), 8 ),
            calc_date = Date.From([assigned_date]) & #time(0, 0, 0) + 
                #duration(
                    Number.From(check_time > 0), 
                    13 - 6 * Number.From(check_time = 1), 
                    0, 0
                )][calc_date]
    )
in
    compliance_date

Hello @Mubar22,

If my post helped you, please give me a 👍kudos and mark this post with Accept as Solution.

I'm not entirely sure I followed your logic. But the following code will definitely help you. Feel free to get in touch if you have any questions.

    ColumnAssignedDateCorrected = Table.AddColumn(PreviousStep, "AssignedDateCorrected", each 
    
    if Time.Hour([assigned_date]) >= 8 and Time.Hour([assigned_date]) < 16
    then Date.AddDays([assigned_date],1) + #duration(0,7,0,0)

    else if Time.Hour([assigned_date]) >=16 and Time.Hour([assigned_date]) < 24
    then Date.AddDays([assigned_date],1) + #duration(0,13,0,0)

    else if Time.Hour([assigned_date]) >=0 and Time.Hour([assigned_date]) < 8
    then [assigned_date] + #duration(0,13,0,0)

    else null)

Hello @Mubar22,

Sorry, I'm not that strong in SQL. I must have misunderstood your query. Maybe @AlienSx solution is a better fit. Otherwise I would tackle your problem again later.
