Ensure that a given date falls on a weekday, instead of over the weekend. This function accepts a date as a parameter, and determines whether or not it falls on a weekend. It allows the user to determine if they want the next weekday, the previous weekday, or the nearest weekday returned. 


Often a program needs to ensure that a calculated date falls on a business day and not a weekend. For instance, automating a series of reminders to contact a customer, review a recurring report, etc. Once your program calculates a date, this function moves it forward or backward and returns a date that is not on a weekend.

How to use:

  1. To get the next weekday date:
  2. Dim dtDate as Date
  3. TextBox = AdjustWeekendDate(dtDate, vbForward)
  4. To get the previous weekday date:
  5. Dim dtDate as Date
  6. TextBox = AdjustWeekendDate(dtDate, vbBackward)
  7. To get the nearest weekday date:
  8. Dim dtDate as Date
  9. TextBox = AdjustWeekendDate(dtDate, vbNearest)

Test the code:

  1. First, open a standalone module and copy and paste the code above into it. Save the module.
  2. Next, open a query and switch from Design View to SQL View. Copy and paste the following SQL statement:
  3. SELECT AdjustWeekendDate(#6/19/2004#,1) AS SaturdayForward, AdjustWeekendDate(#6/19/2004#,2) AS SaturdayBackward, AdjustWeekendDate(#6/19/2004#,3) AS SaturdayNearest, AdjustWeekendDate(#6/20/2004#,1) AS SundayForward, AdjustWeekendDate(#6/20/2004#,2) AS SundayBackward, AdjustWeekendDate(#6/20/2004#,3) AS SundayNearest;
  4. Save the query and then open it. You should see that the requested date is retrieved by the AdjustWeekendDate() function.
