Excel formula for previous weekday

Question

I have a macro in which asks user for a date and it opens the file corresponding to the date and performs some operation. However, instead of entering the date manually I am trying to write an excel function to calculate the previous weekday. This is because the date I usually enter corresponds to the previous weekday.

For example, if today is Monday, I want last week's Friday date- and for the rest of the weekdays upto Friday, it's just the previous day. There won't be files corresponding to weekends.

How can I do this ?

Answer 1

=WORKDAY(TODAY(),-1)

This returns the serial number for the day in Excel, which can just be formatted in the cell.

See here for the full explanation of the function.

Answer 2

Try this in Excel 2010 or later:

=IF ( WEEKDAY (A1, 16) > 3 , A1-1 , A1 - WEEKDAY (A1, 16) )

Adding 16 as the second parameter of WEEKDAY sets Saturday = 1.

Answer 3

In VBA:

Public Function PreviousWeekDay(InputDate As Date) As Integer
    Dim Result As Integer
    Result = Weekday(InputDate, vbMonday)
    If Result = 6 Or Result = 7 Or Result = 1 Then
        Result = 5
    Else
        Result = Result - 1
    End If
    PreviousWeekDay = Result
End Function

Returns 1 = Monday, 2 = Tuesday etc.

Answer 4

=IF(WEEKDAY(NOW()-2)>5,NOW()-WEEKDAY(NOW()-6),NOW()-1)

然后只需格式化单元格，但您希望它显示
