<P> Morning is the period of time between midnight and noon, especially from sunrise to noon . There is no exact time for when morning begins and (equally true with evening and night), because they can vary according to one's lifestyle and the hours of daylight at each time of year . However morning strictly ends at midday (12: 00pm, also called 12: 00 noon), which is when afternoon (ie after noon) starts . Morning can be defined as starting from after midnight (12 am) to noon (12 pm), or from sunrise (which varies throughout the year) to noon, or from when one wakes up to noon . </P> <P> Morning precedes afternoon, evening, and night in the sequence of a day . Originally, the term referred to sunrise . </P> <P> The Modern English words "morning" and "tomorrow" began in Middle English as morwening, developing into morwen, then morwe, and eventually morrow . English, unlike some other languages, has separate terms for "morning" and "tomorrow", despite their common root . Other languages, like German, may use a single word--Morgen--to signify both "morning" and "tomorrow". </P> <P> According to Max Weber (General Economic History pp23), the German word Morgen also takes on another meaning, specifically, the size of land strip "which an ox could plow in a day without giving out". As such, a "good morning" could mean "a good day's plow". </P>
