Good evening in Japanese is こんばんは (konbanwa). Use it when you greet someone in the evening. Do not use おやすみなさい for that greeting: it means “good night” when someone is leaving for bed or ending the night. こんばんは works in both casual and polite situations.
こんばんは ends with the written particle は, even though it is pronounced wa. That is why the standard spelling is こんばんは, not こんばんわ.
Unlike some other greeting pairs, こんばんは works in both normal polite situations and many casual ones. The social nuance usually comes from the rest of the sentence, not from changing the greeting itself.
