Heaven-deaf day
A day pillar traditionally regarded as suitable for various activities.
How did it begin?
The name 天聾日 evokes a heaven that does not hear; the Korean name is also written cheon-rong. Seontaek Giyo preserves seven customary day pillars while acknowledging that their origin is unclear. This information does not guarantee outcomes.
A little more to discover
The public calendar provides dates for 2020–2050. The original list includes 丙申 days and repeats every 60 days independently of lunar months or leap months.
Calculation rules
A day is marked when its pillar matches the list below from Nam Byeong-gil’s Seontaek Giyo (1867), lower volume. It repeats every 60 days independently of the lunar day or solar-term month, and may coincide with other designations. Published event data provides occurrences for 2020–2050. This differs from the lunar and day-pillar conversion range below; years absent from the published calendar are not added to occurrence lists. WhatDay365 uses the device’s local date, changing the day at midnight (00:00). Lunar and day-pillar conversion supports Gregorian dates 1000-02-13 through 2050-12-31; dates outside this range are not estimated.
