Imagine a couple sitting on a couch and one asks the other during Easter "How many Easters are we together?". There is a German wording which goes "Das wievielte Ostern sind wir nun zusammen?" The answer would be "Das ist unser drittes Ostern."
A very "direct" and likely incorrect English translation might be "The howmanieth Easter are we together now?" and the answer could be "It's our third Easter."
Is there a single word which could be used for "wievielte" in English?
As far as I can tell the typical translation is just "How many Easters...". But I'd like to know, if there exists a catchy word which implies an ordinal number as the answer.
