Matt Wills, Virtual Vermont

Adjust a future date so as not to fall on a weekend

Sample Input:
NoWeekend (Any Sat or Sun Date, Type of Avoidance)
Sample Output:
Previous Friday or following Monday Date

 Then copy & paste into FileMaker Advanced's Edit Custom Function window.


Automatically setting a future date (such as for a sales followup in <I>N</I> days or on the first of a month) may return a date which falls on a weekend.

NoWeekend assures that doesn't happen.

Set Avoidance to "C" to return the closest weekday (if the target date falls on Saturday, the previous Friday is returned; if the target date falls on Sunday, the following Monday is returned).

If Avoidance is any other value, the following Monday will be returned.

This CF can be quite useful in conjunction with my <I><a href = "">Holidays</a></I> solution, which projects the dates of specified holidays (Free).

Note: these functions are not guaranteed or supported by Please contact the individual developer with any questions or problems.

This is my Custom Function and I want to edit it


How do I make it so a Friday is returned instead of a Monday?

Hope you can help.

Well I can answer my own question, now that I understand the function better.

To get the Friday before the weekend, just change the second line to:

theDate + Choose ( DayOfWeek ( TheDate ); 0 ; -2 ; 0 ; 0 ; 0 ; 0 ; 0 ; -1)
