One more way is to use SYMNAMES/Symbols since its just a Date field in another Data Set.
I wouldn't argue on poor subject line but I avoid unnecessary use of joinkeys when there is no compare needed or have one to many relationships between two data sets. Nevertheless, TS got the options to choose and should understand the thought process behind each solution.
