"Tuesday comes after Monday."
Translation:मंगलवार सोमवार के बाद आता है।
Yes, you grammatically correct. However, the main subject is Tuesday, and the sentence goes on to provide it's description, i.e. 'comes after Monday'. In your proposed sentence we lose that nuance, because both Monday & Tuesday get equal emphasis - to a native Hindi speaker at least. I agree that it's quite subtle. But nevertheless, it's there.
