Baby crying nonstop from 7pm to 12am

Hi, my 6 weeks old baby always cry from 7pm to 12am everyday for almost a week. No matter what we do (pat him, rock him, carry him walking around the house, sing song etc) he just can't stop crying. Yesterday i finally snapped and yelled at him bcz I really don't know what he wants with all these crying. Any mummy facing the same issue and how do u solve this?
