How to calculate business days?

[Belini]

I need to know how many days business have in a given period eg 04/27/2014 to 10/05/2014, there is filtering function to do this?

[water]

There is no ready-to-use function I know of

But you could use functions _DateToDayOfWeek and _DateAdd in a loop to calculate the number of work days.

How would you handle holidays?

[JustSomeone]

And a small reminder :  Keep in mind that in different countries the workdays are different, and depending on holidays.

[Belini]

Holidays are really a problem, I have to create an .ini file Containing all holidays.

[JustSomeone]

Usually, most of the countries publish such info on official sites, so you can put both the workdays and the holidays inside an ini if needed

[sahsanu]

Just a quick sample without taking care of public holidays, etc. and bussiness days from Monday to Friday:

#include <Date.au3>
$sStartDate = "2014/04/27"
$sEndDate = "2014/05/10"

$iBussinessDays = _BussinessDays($sStartDate, $sEndDate)
ConsoleWrite("There are " & $iBussinessDays & " bussiness days between " & $sStartDate & " and " & $sEndDate & @CRLF)

Func _BussinessDays($sStartDate, $sEndDate)
    $iCounter = 0
    $iDifferenceInDays = _DateDiff('D', $sStartDate, $sEndDate)
    For $i = 0 To $iDifferenceInDays
        $sNextDate = _DateAdd('D', $i, $sStartDate)
        $aSplitDate = StringSplit($sNextDate, "/")
        $sDayOfWeek = _DateToDayOfWeekISO($aSplitDate[1], $aSplitDate[2], $aSplitDate[3])
        If $sDayOfWeek >= 1 And $sDayOfWeek <= 5 Then
            $iCounter += 1
        EndIf
    Next
    Return $iCounter
EndFunc   ;==>_BussinessDays

Cheers,

Thanks to all who responded, @ sahsanu I'll put the holiday in your example and will stay as I want.

My coding might be a bit sloppy, but here is my attempt at finding holidays, both set days and floating days.

expandcollapse popup

#include <Date.au3>

#cs

SHDay are Set Holidays.  The month and days are the same each year.
Set Days:
new years day; 01,01
july 4th; 07,04
christmas day; 12,25


VHDay are Variable Holidays. The month and days may vary on:

Variable Days:

MLKJr Day; 1,3,2 (3rd Monday in January)
President's Day; 2,3,2 (3rd Monday in February)
Labor Day; 9,1,2 (1st Monday in September)
Thanksgiving Day; 11,4,5 (4th Thursday in November)

Memorial Day Exception:
Memorial Day Last Monday in May (see May calculation)

Easter (see Easter Mess)
Good Friday (friday before easter)


Non-Bank Holidays:
Father's Day; 6,3,1 (3rd Sunday June)
Mother's Day; 5,2,1 (2nd Sunday in May)

could always use excel, NETWORKDAYS(), make a range for you're holidays and that way you're spreadsheet will auto update.

Could use autoit to work with excel to take the number of workdays, also to put in any holidays etc... i know nothing what you're after but just another approach which is VERY simple to do in excel quickly and can still use autoit to work with it thanks to water.
