Sunrise is the moment when the upper rim of the Sun appears on the horizon in the morning. The term can also refer to the entire process of the solar disk crossing the horizon.

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 because it can vary according to one's lifestyle and the hours of daylight at each time of year. However, morning strictly ends at noon, which is when afternoon starts.
