hola amable comunidad

 

Requiero de su apoyo para poder sumar 5 dias habiles (no contar sabados ni domingos) a una fecha tipo DateTimezone

 

Tengo un campo Date con miles de fechas, por ejemplo esta fecha (26/05/2023 6:00:00 PM) al sumar los 5 dias habiles mi fecha de salidad debe ser 02/06/2023 6:00:00 PM

 

Gracias

Your examples are of the DateTime type,  NOT DateTimeZone.  Accordingly, the below code for a Power Query function uses DateTime.  You should be able to adapt it to your actual problem

 

Also, the code is more generalized and includes an optional Holidays list. You can create the list yourself, which, if you have thousands of dates, would be more efficient, as the code will download an appropriate list each time it executes.

 

//Note optional Holidays parameter
//You can substitute a self-generated List of holidays, or use the website in the code to download a list
//  If you use the website, be sure to use a recognized country abbreviation
//If you are using holidays, you should separate this list and buffer the result for speed issues.
//  as written, it will download this list every time the function executes

(start as datetime, numDays as number, optional Country as nullable text) =>

let 
    adjNumDays = Number.RoundAwayFromZero(Number.Abs(numDays*7/5))*2,
    yrStart = Date.Year(start),
    yrEnd = Date.Year(Date.AddDays(start,adjNumDays*Number.Sign(numDays))),

//Create list of country specific Holidays
    yrs = {List.Min({yrEnd,yrStart})..List.Max({yrEnd,yrStart})},

    holidays = if Country = null then {} else    
        List.Accumulate(yrs,{},(state,current) =>
             let 
                Source=Web.Page(Web.Contents("https://www.officeholidays.com/countries/" & Country & "/" & Number.ToText(current))),
                Data0 = Source{0}[Data],
                DateCol = Table.SelectColumns(Data0,"Date"),
                fullDate = List.Transform(DateCol[Date], each Date.FromText(_ & " " & Number.ToText(current)))
            in   
                state & fullDate),

//all Working dates
//Generates a list of working dates in either Ascending or Descending order
//  based on the Sign of numDays
//  starting with the first working date after Start
    allWorkDates = 
        List.RemoveNulls(
            List.Transform(
                List.DateTimes(start, adjNumDays, #duration(Number.Sign(numDays),0,0,0)),
                    each if _ = start then _ 
                            else 
                                if Date.DayOfWeek(_)=Day.Saturday 
                                    or Date.DayOfWeek(_)=Day.Sunday 
                                    or List.Contains(holidays, Date.From(_))
                                then null 
                                else _)),
    addWorkDays = if numDays = 0 then start else allWorkDates{Number.Abs(numDays)}
    
in
    //List.DateTimes(start, adjNumDays, #duration(Number.Sign(numDays),0,0,0))
    //adjNumDays
    addWorkDays
