"visitors": indicates the royal family of the Xia and Shang (previous dynasties) who the Zhou called 'visitors' because they didn't dare consider them subjects.
"day and night": early to rise and late to bed, indicates they are busy working
So it's about the previous dynasty coming to the Zhou for rites, praising that they can get along in harmony.
