Lots of ways to do this depending on your preference. The following function return the first weekend date for whatever DATE you enter:
SET VAR vToday DATE = (DWE(.#DATE)) Now you have the next Saturday’s date, so you just need to subtract 5 days for the previous Monday and 1 for the previous Friday. set var vStart DATE = (ADDDAY(.vToday, -5)) set var vEnd DATE = (ADDDAY(.vToday, -1)) And you will have the beginning and end dates for the week and you can easily format them. You can probably combine the commands into one long command, but it would be more difficult to read in the future. You can also use the function IDWk which will tell which day of the week for any date. Then you can use a simple CASE construct to add or subtract days accordingly. I can think of other ways but the ones I mentioned are simple and easy to understand. Hopefully, this is what you were looking for.

However, now I have another challenge that so far eludes me. So I know that using (IWOY(.#DATE)) today will 13. But I'm really trying to find out what the Monday and Friday of Week 13 are so I can display something like "Week of 3/21 - 3/26". Any suggestions appreciated.

Then you can just count the number of rows between any two dates where the flag = 'Y'. I actually had an app with 2 flags because the company was a car auction so actual business days for sellers and buyers were not always the same so there was a flag for each because sometimes it might not be a business day for the sellers if you cant go pickup cars because of a snowstorm, but are open for buyers who can make in to the location to pay their bills. This data was used for calculating buyer storage and seller pickup SLA reports. Just depends on your application and what you need to accomplish with it.

Use the IDWK function to exclude the 6th and 7th (Saturday and Sunday) day of the Week. -- IDWK returns the day of the week where Monday is 1. -- Example 01 SELECT * FROM tablename WHERE (IDWK(datecolumn)) NOT IN (6,7) -- Example 02 SELECT * FROM tablename WHERE (IDWK(datetimecolumn)) NOT IN (6,7) That's all there is to it!
