Parts of the day
The second part of the day is afternoon. The English afternoon is the time from 12 o'clock a.m. to 6 o'clock p.m. In the afternoon people say "Good afternoon". In the afternoon we come home from school.
Evening is the third part of the day. It is the time from 6 o'clock p.m. till sunset. In the evening we do our homework: we read and write, learn English, history, literature, mathematics, physics and other subjects. When friends come, they say "Good evening".
