60일 주기
Great void day
A day referenced in traditional texts for grave relocation, breaking ground, tending graves and placing memorial stones.
How did it begin?
Nam Byeong-gil’s Seontaek Giyo (1867), lower volume, records twelve day pillars for grave relocation when birth-year information or the existing orientation is unknown, or the work is urgent. This list differs from xun-based empty branches (旬中空亡) and does not guarantee fortune or safety.
A little more to discover
The public calendar provides dates for 2020–2050. The day pillar changes at local midnight 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.
