Questions & Answers about На концерте она была в шляпе, а после концерта убрала шляпу в большую сумку.

Why is it на концерте, but после концерта?

Because different prepositions require different cases.

• на концерте = на

  • prepositional case
  • концерт → концерте
  • Here it means at the concert

• после концерта = после

  • genitive case
  • концерт → концерта
  • Here it means after the concert

So the noun changes because the preposition changes.

Why does Russian use на концерте instead of something like в концерте?

Russian often uses на with events and activities:

• на концерте = at a concert
• на уроке = in class / at the lesson
• на работе = at work
• на встрече = at a meeting

This is just the normal Russian pattern. Even though English often says at or in, Russian commonly uses на for many events.
