In Korean folk belief, 'Son' refers to a spirit that wanders the four directions and brings misfortune. On days when the lunar date ends in 9, 10, 19, 20, 29, or 30, the spirit is said to be in the sky, leaving all directions free — these are called 'Son-Eopneun-Days' (days without Son).
Traditionally, Koreans pick these days for moving house, opening a new business, getting married, or relocating gravesites. This is folk tradition without scientific basis. Please prioritize your own schedule, budget, and practical logistics when making real decisions.
Choose the year and month you want to check.

Son-Eopneun-Days drive up demand. Get at least 3 quotes before booking.
Don't forget address-change registration, gas stop/connect, and internet transfer booking.
Finish opening ritual prep, banners, and flower arrangements at least a week in advance.
Secure a backup in case elevator or parking slots are unavailable.
In traditional Korean directional folklore, the 'Son' spirit stays in specific compass directions depending on the date's last digit. On the six days listed, Son ascends to the sky, freeing all directions for movement.
No. It is pure folk tradition with no legal or scientific obligation. Family schedule, moving company availability, and budget are far more important.
Demand concentrates on Son-Eopneun-Days, pushing moving-company quotes 20–40% higher. If your budget is tight, compare weekdays and off-peak seasons first.
Multiple lunar-calendar implementations exist. This tool uses the lunar-javascript library. For critical decisions, cross-check with an official source such as the Korea Astronomy and Space Science Institute (KASI).
Tradition advises avoiding bad weather (rain, snow, strong wind) even on Son-Eopneun-Day. In practice, weather forecasts, elevator reservations, and traffic conditions matter much more.
Son-Eopneun-Day is a traditional Korean lucky day chosen for moving, opening, or weddings. It is based on lunar dates ending in 9, 10, 19, 20, 29, or 30 — roughly 4–6 days per solar month.
In 2026, there are roughly 70 Son-Eopneun-Days on the solar calendar. Expect higher moving-company quotes during peak moving seasons (March, October) and around major Korean holidays.
