morning

Morning is the period from sunrise to noon. It is preceded by the twilight period of dawn. There are no exact times for when morning begins (also true of evening and night) because it can vary according to one's lifestyle, latitude, and the hours of daylight at each time of year. However, morning strictly ends at noon, which is when afternoon starts.
Morning precedes afternoon, evening, and night in the sequence of a day. Originally, the term referred to sunrise.
