In Swedish if you "eat midday" (äter middag), you're eating dinner. I thought the Danes were the reasonable ones, but TIL that "middagsmad" (midday food) means dinner there too.

I knew that they were funny about "frokost" (early meal) meaning lunch. In Norwegian (bokmål: "frokost") and Swedish ("frukost") it means breakfast.

Swedish and Danish have an alternative, reasonable word "kvällsmat"/"aftenmad" (evening food) that also means dinner. In Swedish it's used about as often as the silly one. The reasonable one is considered a bit less formal.
