Gammeldags/old fashioned/square

From Kunnskapsforlaget's Norsk-Engelsk Stor Ordbok:

gammeldags old-fashioned, out of date, outdated, dated, antiquated, square (colloquial)

My beef with this definition is the inclusion of the word "square." This sense of "square" as meaning dated is itself quite dated. This use probably peaked around 1960 and certainly fell out of fashion by the 1980s. Which means that it has not been used this way for 30 years! And if you were a native speaker of Norwegian, relying on this dictionary to help you use decent-sounding English. The use of this word in this sense would make you sound silly. And quite out of date...

Methinks the dictionary could use a little updating.
