вече
"Вече" in Serbian means "evening" in English.
In this sentence, 'вече' refers to the time of the day, specifically the evening.
Вече је било веома мирно и тихо.
The evening was very calm and quiet.
Here, 'вече' is part of 'вечера' ('dinner') and indirectly indicates evening time during which meals are often shared.

We invited all our friends for the dinner.
Here, 'вече' again refers to the time period of the evening with a nuance of relaxing and spending time with others.
