Android Question Days elapsed in a month

Brian Michael · Dec 8, 2020

Hi B4X Dev's:

Hi i make another sub for get the day elapsed in the month

B4X:

Public Sub CurrentLaborableDays(Date As Long, Mode As Int) As Int
    
    Dim days_count As Int = DateTime.GetDayOfMonth(Today)
    
    Dim AD As Avalibles_Days
    AD.Initialize
    
    Select Mode
        Case 1 'DAYS WITHOUT SATURDAY AND SUNDAY
            AD.Monday = True
            AD.Tuesday = True
            AD.Wednesday = True
            AD.Thursday = True
            AD.Friday = True
            AD.Saturday = True
            AD.Sunday = False           
        Case 2 'DAYS WITHOUT SUNDAY
            AD.Monday =True
            AD.Tuesday =True
            AD.Wednesday =True
            AD.Thursday =True
            AD.Friday =True
            AD.Saturday =False
            AD.Sunday =False
        Case Else 'ALL DAYS
            AD.Monday =True
            AD.Tuesday =True
            AD.Wednesday =True
            AD.Thursday =True
            AD.Friday =True
            AD.Saturday =True
            AD.Sunday =True
    End Select
    
    Dim days_result As Int = 0

    For i = 1 To days_count
        Dim day As String =  i & "/" & DateTime.GetMonth(Date) & "/" & DateTime.GetYear(Date)
        'My language is spanish that's the reason the days are in spanish, but you can change it for your language:

        Dim l As Long = DateTime.DateParse(day)
        day = DateUtils.GetDayOfWeekName(l)
        If day = "lunes" And AD.Monday = True Then days_result = days_result + 1
        If day = "martes" And AD.Tuesday = True Then days_result = days_result + 1
        If day = "miércoles" And AD.Wednesday = True Then days_result = days_result + 1
        If day = "jueves" And AD.Thursday = True Then days_result = days_result + 1
        If day = "viernes" And AD.Friday = True Then days_result = days_result + 1
        If day = "sábado" And AD.Saturday = True Then days_result = days_result + 1
        If day = "domingo" And AD.Sunday = True Then days_result = days_result + 1
    Next
    
    Return days_result
End Sub

How to use the sub:

B4X:

CurrentLaborableDays(Date as Long, Mode as Int) as Int
'Date is the current day
'Example: Let's say the month is December, if you put the "Current day" = 12/8/2020 when you run the function in
'Mode 0 = 8, Mode 1 = 7, Mode 2 = 6

'Mode 0 = All Days
'Mode 1 = Days With out Sunday
'Mode 2 =  Days With out Saturday and Sunday


Log("Days: " & CurrentLaborableDays(DateTime.DateParse("12/8/2020"),0))
'Result 8

Log("Days: " & CurrentLaborableDays(DateTime.DateParse("12/8/2020"),1))
'Result 7

Log("Days: " & CurrentLaborableDays(DateTime.DateParse("12/8/2020"),2))
'Result 6

Select Mode Case 1 'DAYS WITHOUT SATURDAY AND SUNDAY AD.Monday = True AD.Tuesday = True AD.Wednesday = True AD.Thursday = True AD.Friday = True AD.Saturday = True AD.Sunday = False

must AD.Sunday not be true for case 1?

Case 2 'DAYS WITHOUT SUNDAY

Days without sunday implies Saturday for me.

You are missing to post the needed Custom type.

Moved to the questions forum as the code is broken and there are much better ways to do it.

Depends on DateUtils and B4XCollections:

B4X:

Sub AppStart (Args() As String)
    Dim InterestingDays As B4XSet = B4XCollections.CreateSet2(Array(1, 2, 3, 4, 5)) 'without friday and saturday
    Log(CountSpecificDaysInMonth(2020, 12, InterestingDays))
End Sub

Sub CountSpecificDaysInMonth (Year As Int, Month As Int, RelevantDays As B4XSet) As Int
    Dim day As Long = DateUtils.SetDate(Year, Month, 1)
    Dim p As Period
    p.Days = 1
    Dim total As Int
    Do While DateTime.GetMonth(day) = Month
        If RelevantDays.Contains(DateTime.GetDayOfWeek(day)) Then total = total + 1
        day = DateUtils.AddPeriod(day, p)
    Loop
    Return total
End Sub

Hi @DonManfred and @Erel

Thanks for answer, this function can be added to DateUtils:

    Return total
