Aura & Doobie - Купалле [Belarusian Song] Translation

Ноччу на Купалле
Хлопцы гулялі
Дзеўчыны гукалі
Папараць шукалі

Thank you to anyone who helps

I'm not sure for translation...I know russian and ukrainian, but belarusian is a mix of this languages as i know

In the evening on Kupala (it is such holiday on the 7th of July)
The boys were playing (it is such old tradition)
Calling the girls
Was searching the fern.
