I have a field {arrival} which is a date. I want to display {arrival+3}, expressed as a day of the week. So if {arrival} is a Friday, I want to be able to output "Monday" in my document. I tried { ={arrival \@ "dddd"} + 3} thinking that the days of the week would cycle at the end of month anyways but that gave me an "undefined bookmark" error.
Help?
