Originally posted by: mmarinelliWhile such an operator is planned for a future release, there currently isn't a BRAINScript function to do this. However, you can work around this using the current set of operators. I've attached a graph which illustrates how to determine the day of week for any date. It requires the seeding of the filter node with a known Sunday anchor date (I chose 2009-06-28), and I don't think it will work with any dates before 1970, but it should otherwise do what you're looking for.
