How to read the day pillar and solar terms
The day pillar (iljin) is the sexagenary name given to each day. Ten heavenly stems and twelve earthly branches pair up in turn, so the same name returns every 60 days. A manseryeok lists the pillars of the year, month, day and hour, and the day pillar in Korean saju (Four Pillars) is the day pillar of the birth date.
The 24 solar terms divide the Sun’s path into 15° steps. They follow the solar calendar, so they fall on nearly the same dates every year, and each begins at an exact minute. Times are Korea Standard Time (UTC+9).
Lunar dates and day pillars come from the korean-lunar-calendar library (Korea Astronomy and Space Science Institute tables). Solar term times come from the manseryeok library, matched to KASI’s tables to the minute.
