VBA Function to Compare Dates

September 26th, 2008 | Categories: VBA | Tags: , , ,

The following VBA function will check if a given date is between two other dates and if so, it will return the value TRUE. If the date is not in between the dates, then it will return the value FALSE.

Function buy viagra pills Compare_Dates(Start_Date As Date, End_Date As Date, Other_Date As Date) As Boolean
' Boolean Function to compare dates
'Will return TRUE only when Other_Date is between Start_Date and End_Date
'Otherwise will return FALSE
'Set outcome to FALSE - default value
Compare_Dates = False
'Compare Dates
If ((Other_Date >= Start_Date) And (Other_Date <= End_Date)) Then

'If Other Date is between Start and End Date then set to true
Compare_Dates = True

End If
End Function

The function has three arguments:
• Start_ date – the earliest allowable date
• End_ Date – the latest allowable date
• Other_Date – the date being compared

The function must be in an Excel module. It can be run from an Excel Workbook e.g:

A4= Compare_Dates(21-06-2003,12-02,2008,15-09-2008)
A3 =Compare_Dates(A1,A2.A3)
A1= Compare_Dates(13-03-2005,18-08-2005,A6)
So Compare_Dates(25-04-2007,12-07-2008, 23-06-2006) will give the value TRUE as 23-06-2006 is between 25-04-2007 and 12-07-2008.

Likewise Compare_Dates(19-07-2003,12-12-2001,12-08-2008) will return FALSE as 12-12-2001 is NOT between 19-07-2003 and 12-08-2008
