Share - calculate working days between two given dates

Hello, I was trying to find the method to return the number of working days between two given dates and found the following article

 

https://powerapps.microsoft.com/en-us/blog/excluding-weekends-and-holidays-in-date-differences-in-po...

 

However, as the author mentioned "Notice that the partial week calculation given above will not work if the start or end dates fall on weekends"

 

So I spent some time writing the following formula which seems work for weekends too:

 

If(IsNewRequestFormValid, RoundDown(DateDiff(DatePickerFrom.SelectedDate, DatePickerTo.SelectedDate, Days) / 7, 0) * 5 +
If(Weekday(DatePickerTo.SelectedDate) >= Weekday(DatePickerFrom.SelectedDate),
If(Weekday(DatePickerTo.SelectedDate) = Weekday(DatePickerFrom.SelectedDate) && (Weekday(DatePickerTo.SelectedDate) = 1 || Weekday(DatePickerTo.SelectedDate) = 7),
0,
If(RoundDown((Weekday(DatePickerTo.SelectedDate) - Weekday(DatePickerFrom.SelectedDate))/5,0) >= 1,
5,
If(Weekday(DatePickerTo.SelectedDate) = 7,
Weekday(DatePickerTo.SelectedDate) - Weekday(DatePickerFrom.SelectedDate),
If(Weekday(DatePickerFrom.SelectedDate) = 1,
Weekday(DatePickerTo.SelectedDate) - Weekday(DatePickerFrom.SelectedDate),
Mod(Weekday(DatePickerTo.SelectedDate) - Weekday(DatePickerFrom.SelectedDate), 5) + 1)))),
(7 - Weekday(DatePickerFrom.SelectedDate) + Weekday(DatePickerTo.SelectedDate) - 1)))

 

I am sure it can be improved, so please feel free to make any enhancement.

thanks for sharing but;

  1. What is IsNewRequestFormValid? is it a custom variable just for your case?

I don't know what you mean by working day but my requirement excluded bank holidays so Christmas Day, New Years day don't count as working days.  Here is list:

 

DescriptionHolidayDate
New Year's Day1/1/2019
Birthday of Martin Luther King, Jr.1/21/2019
Washington's Birthday2/18/2019
Memorial Day5/27/2019
Independence Day7/4/2019
Labor Day9/2/2019
Columbus Day10/14/2019
Veterans Day11/11/2019
Thanksgiving Day11/28/2019
Christmas Day12/25/2019
New Year's Day1/1/2020

 

I also need to add/subtract working days from a date.  For example something is due in 10 business days (BD) or send a reminder notice 3 BD prior to due date.  The date could be a non workday.  I found using PA to do this was impossible.  I ended up doing an Azure Function.  

Just to add a bit to this great thread, if you want to exclude public holidays/company days etc you just need to do the following (assuming SharePoint is the data source)

 

  • Create a new custom list with a couple of columns (Holiday Type, Date).  I made the Holiday column a choice one but that is up to you as this is purely used for reference by the person entering the dates.

 

pa-splist.png

 

  • Add this list as a data source in your app
  • Add the following code to the end of the code provided by @Li   (note the minus sign before CountIf)

 

- CountIf('Company & Public Holidays',Date >= DatePickerFrom, Date <= DatePickerTo)

 

  • Now the formula will remove and days from the total that are on the new list and fall between the to/from dates selected.

Thank @Rob_CTL and @Li - This has all been very helpful, but I have one problem. My company has 6 different regions with different public holidays.

 

For Public Holidays I have a single SharePoint List WIth 12 Columns, "Region 1 Holiday Name"; "Region 1 Holiday Date"; etc.

 

Another SharePoint List contains the "Staff Name", the "Region" they work in and other details.

 

How can I add to this formula - CountIf('Company & Public Holidays',Date >=DatePickerFrom, Date <=DatePickerTo) to determine from the inputted staff name, what region they are in and select the corresponding holiday dates column?

 

Thanks

I doubt this will help you but I had a lot of complicated date calculations.  I have a table that lists the bank holidays.  I was using SQL Server.  I ended up writing and Azure Function in C#.  It calculates the due date for some task and sends out an email.  I am very pro Azure Functions.  They are a great compliment to PowerApps and keep the app very simple while adding complex functionality.

 

 

        public static DateTime CalcDate(DateTime date, string dueDateOffset, Dictionary<DateTime, int> hd)
        {
            int dCnt = 0;
            DateTime calcDate = new DateTime(1900, 1, 1);
            string[] parts = dueDateOffset.Split('|');
            if (parts[0] == "CD")
            {
                if (Int32.TryParse(parts[1], out dCnt))
                {
                    calcDate = date.AddDays(dCnt);
                }
                else

                        }

                date = new DateTime(date.Year, date.Month, 15);

                }
            }

            return calcDate;
        }

 

Thank you. I will try and break this down but it's clear I am out of my depth here.

 

This is what I have so far, and without the countif statement at the end, it works to eliminate the weekends from between the dates chosen.

 

RoundDown(DateDiff('Leave Start Date_DatePicker'.SelectedDate, 'Leave End Date_DatePicker'.SelectedDate, Days) / 7, 0) * 5 +
If(Weekday('Leave End Date_DatePicker'.SelectedDate) >= Weekday('Leave Start Date_DatePicker'.SelectedDate),
If(Weekday('Leave End Date_DatePicker'.SelectedDate) = Weekday('Leave Start Date_DatePicker'.SelectedDate) && (Weekday('Leave End Date_DatePicker'.SelectedDate) = 1 || Weekday('Leave End Date_DatePicker'.SelectedDate) = 7),
0,
If(RoundDown((Weekday('Leave End Date_DatePicker'.SelectedDate) - Weekday('Leave Start Date_DatePicker'.SelectedDate))/5,0) >= 1,
5,
If(Weekday('Leave End Date_DatePicker'.SelectedDate) = 7,
Weekday('Leave End Date_DatePicker'.SelectedDate) - Weekday('Leave Start Date_DatePicker'.SelectedDate),
If(Weekday('Leave Start Date_DatePicker'.SelectedDate) = 1,
Weekday('Leave End Date_DatePicker'.SelectedDate) - Weekday('Leave Start Date_DatePicker'.SelectedDate),
Mod(Weekday('Leave End Date_DatePicker'.SelectedDate) - Weekday('Leave Start Date_DatePicker'.SelectedDate), 5) + 1)))),
(7 - Weekday('Leave Start Date_DatePicker'.SelectedDate) + Weekday('Leave End Date_DatePicker'.SelectedDate) - 1)) - CountIf('Public Holidays', NSW >= 'Leave Start Date_DatePicker'.SelectedDate, NSW <= 'Leave End Date_DatePicker'.SelectedDate)
