Ipchun(beginning of Spring), Usu(the first rainfall of the year)
Traditional Chinese calendar divides a year into 24 solar terms.
Ipchun, the first of the twenty four seasonal divisions, falls around the third or fourth of February by the solar calendar.
Ipchun, the onset of spring according to the lunar calendar, signals the beginning of the farming year. Farmers repair equipment and tools, exchange information and spread fertilizer on fields. Koreans sometimes forecast the outcome of the year's harvest at this time from the number of roots on barley seedlings and the intensity of the wind. Many families hang a card at the entrance to their homes reading Ipchun Daegil, Good fortune with the onset of spring.
