Every judgment on this site is calculated from a real lunar-calendar table covering 1900 to 2100 (73,414 days). AI only writes the explanation.
“Son(손)” is a spirit believed to roam the four directions, and on lunar days ending in 9 or 0 it is said to have gone up to the sky — leaving no direction blocked. So lunar 9, 10, 19, 20, 29 and 30 are traditionally chosen for moving and for opening a business. Six days a month, always.
Each day carries one of twelve gods, decided by the day branch against the month branch. Different purposes favour different gods.
| Purpose | Favoured | Avoided |
|---|---|---|
| 📦 Moving | 成(성) · 開(개) · 滿(만) · 平(평) · 定(정) | 破(파) · 危(위) · 閉(폐) |

Twelve day-gods rotate from a starting branch set by the month. Six of them — Cheongryong, Myeongdang, Geumgwe, Cheondeok, Okdang, Samyeong — are “hwangdo”, the auspicious half.
This is the part a printed calendar cannot do for you. Enter your birth date and we read your year branch from the same lunar table, then remove every day whose branch is directly opposite yours — three days in a typical month.
We do not predict your fortune, promise outcomes, or push you to pay for a “better” day. The calendar is free forever. Credits only cover the personalized ranking and its explanation. Days outside 1900-2100 are refused rather than invented.
