"You should have gone to church on Sunday."
Translation:Du skulle ha gått i kirken på søndag.
You're welcome! I find that one of the most frustrating parts about learning a new language is making sense of the prepositions. They are often arbitrarily chosen, often differ wildly between languages and can often bear a lot of meaning -- like in this example. I guess the only good solution is just memorizing and internalizing the different uses.
