DateDiff

varDateDiff,这是使用了DateDiff 来计算两个date之间有多少天. 

Set(
    varDateDiff,
    DateDiff(
        HolidayCalculation.StartDate,
        HolidayCalculation.EndDate,
        Days
    )
);

Date Diff Except Holiday

varDateDiffExceptHoliday计算出同时除去周末以及假期

Set(
    varDateDiffExceptHoliday,
    RoundDown(
        DateDiff(
            HolidayCalculation.StartDate,
            HolidayCalculation.EndDate,
            Days
        ) / 7,
        0
    ) * 5 + Mod(
        5 + Weekday(HolidayCalculation.EndDate) - Weekday(HolidayCalculation.StartDate),
        5
    ) - CountRows(
        Filter(
            HolidayCalculation.HolidayRecord,
            HolidayDate >= HolidayCalculation.StartDate,
            HolidayDate <= HolidayCalculation.EndDate
        )
    )
);

Date Diff Except Weekend

计算出除去周末以外的天数

Set(
    varDateDiffExceptWeekend,
    RoundDown(
        DateDiff(
            HolidayCalculation.StartDate,
            HolidayCalculation.EndDate,
            Days
        ) / 7,
        0
    ) * 5 + Mod(
        5 + Weekday(HolidayCalculation.EndDate) - Weekday(HolidayCalculation.StartDate),
        5
    ));

TargetDateExceptHoliday

计算出除去周末以及holiday以外的最终目标天数

Clear(varDateRange);
ForAll(
    HolidayCalculation.DatePeriod,
    Collect(
        varDateRange,
        {
            RowIndex: CountRows(varDateRange) + 1,
            Date: DateAdd(
                HolidayCalculation.StartDate,
                Value
            )
        }
    )
);

RemoveIf(
    varDateRange,
    Weekday(Date) = 1 || Weekday(Date) = 7 || CountRows(
        Filter(
            HolidayCalculation.HolidayRecord,
            HolidayDate >= Date, 
            HolidayDate <= Date
        )
    ) > 0
);

Set(varTargetDateExceptHoliday, Last(FirstN(varDateRange, HolidayCalculation.NumberOfDays)).Date);
