In a desktop flow, I am creating a flow that identifies the most recent weekday date on or before yesterday.
I think that I can identify the most recent weekday by listing holidays as shown in the attached Excel and determining whether the date before yesterday is included in it, but I am struggling with how to express it as a flow, and I am wondering if anyone can give me some advice. I would be very grateful if anyone could cooperate.
Please follow the suggested flow.
We utilize an Excel sheet to store holiday data. This data is then converted into a list and passed as an input parameter to the .NET script. The script processes the input date and performs necessary calculations to determine the last weekday prior to the entered date.
.Net scripts do the math and it will return the last week day of entered date by excluding week dates holidays list.
Code:
Excel.LaunchExcel.LaunchAndOpenUnderExistingProcess Path: $'''C:\\Users\\Documents\\Holidays.xlsx''' Visible: True ReadOnly: False Instance=> ExcelInstance
Display.InputDialog Title: $'''Enter enter the date to check''' Message: $'''Enter enter the date to check in the format of (YYYY/MM/DD)?''' InputType: Display.InputType.SingleLine IsTopMost: False UserInput=> EnteredDate ButtonPressed=> ButtonPressed2
SET Out_Date TO $'''%''%'''
Excel.ReadFromExcel.ReadAllCells Instance: ExcelInstance ReadAsText: False FirstLineIsHeader: False RangeValue=> ExcelData
Variables.RetrieveDataTableColumnIntoList DataTable: ExcelData ColumnNameOrIndex: 0 ColumnAsList=> HolidayAsList
Scripting.RunDotNetScript Language: System.DotNetActionLanguageType.CSharp Script: $'''
// Step 1: Calculate Yesterday\'s Date
DateTime yesterday = Convert.ToDateTime(In_Date).AddDays(-1);
// Step 2: Check if Yesterday is a Weekday
while (yesterday.DayOfWeek == DayOfWeek.Saturday || yesterday.DayOfWeek == DayOfWeek.Sunday)
{
yesterday = yesterday.AddDays(-1); // Move to previous day
}
// Step 3: Check if Yesterday is a Holiday
while (holidays.Contains(yesterday))
{
yesterday = yesterday.AddDays(-1); // Move to previous day
}
// Step 4: Output the Most Recent Weekday Date on or Before Yesterday
Out_Date= yesterday.ToString(\"yyyy-MM-dd\");''' @'name:holidays': HolidayAsList @'type:holidays': $'''List''' @'direction:holidays': $'''In''' @'name:In_Date': EnteredDate @'type:In_Date': $'''String''' @'direction:In_Date': $'''In''' @'name:Out_Date': $'''''' @'type:Out_Date': $'''String''' @'direction:Out_Date': $'''Out''' @Out_Date=> Out_Date
Display.ShowMessageDialog.ShowMessage Title: $'''Last week day''' Message: $'''Last week day is : %Out_Date%''' Icon: Display.Icon.None Buttons: Display.Buttons.OK DefaultButton: Display.DefaultButton.Button1 IsTopMost: False ButtonPressed=> ButtonPressed

他の回答者の方が仰っているようにDayOfWeekプロパティで曜日を取得できますので、このプロパティを使って土日の判定、さらに別途祝日判定用のリストやデータテーブルを用意することで祝日も含めて判定できるかと思います。
祝日判定用のデータテーブルを使った簡単なフローを作成してみましたのでご参考いただければ幸いです。
(処理の詳細はコメントをご参照ください)
作成したフローは下記サイトにアップしていますので、コードをコピーしてデザイナー画面に貼り付けることで動作確認できます。
On datetime you can you DayOfWeek. So %CurrentDateTime.DayOfWeek% and that gives you weekday like "Thursday".
Here is logic how you can check is yesterday or day before was weekend or weekday.
Do you need to have also holidays like Christmas and national holidays? If so then that can vary depending on country. So you might need to use an API for that.
