What time do you stop using 아침 and start using 오전? : 아침 is same in English 'morning' , 오전 is same with morning. that mean 'before at noon' when does 오후 stop and 저녁 start (I'm guessing 6pm?) : 오후 is same in English 'afternoon' 저녁 is same in English 'evening', 'dusk' When does 저녁 stop and 밤 start? : 저녁 is evening ( before sunset ) 밤 is night ( after sunset )

sorry,I dont know the Korean:)

hi this is a useful site as well; Telling Time, Dates, Weather, Seasons, Numbers ... http://www.carla.umn.edu/assessment/VIB/korean/novice/listening/nl-time-date-weather-season-numbers.html. www.carla.umn.edu/.../korean/.../nl-time-date-weather-season-numbers.html -

To tell time, you use * the Pure Korean number for the hour, followed by * the classifier for hours, si. If there are any minutes, follow this with: * the Sino-Korean number of minutes and * the word for minutes, pun Examples: 5:20 = taseossi @isippun 7:43 = @ilgopsi sasipsampun 2:15 = dusi sip@opun 1:39 = hansi samsipkupun Notice in the last two examples that the pure Korean hour has changed form before the si.
