Son-eomneun-nal is a traditional Korean auspicious day for moving, referring to lunar dates ending in 9 or 0. Specifically, lunar days 9, 10, 19, 20, 29, and 30 are considered Son-eomneun-nal, occurring about 6 days per month.

"Son" refers to wandering spirits or guest gods, and these days are believed to be when such spirits do not visit the human world. Therefore, they are considered good days for important activities like moving, business openings, and home repairs. There is a belief that choosing Son-eomneun-nal for moving brings good fortune to the new home and helps avoid misfortune.

This tradition has been passed down as folk belief since the Joseon Dynasty, and many people still consider Son-eomneun-nal when deciding moving dates. Although there is no scientific basis, it remains important for psychological comfort and wishing for a good start.

Traditionally, moving on Son-eomneun-nal is believed to bring various positive effects. First, since it is a day without spirits, bad energy is not believed to follow to the new home. Second, the moving process is believed to proceed smoothly without accidents or problems.

Third, it signifies that family health and fortune will accompany them in the new home. Fourth, there is a belief that wealth luck improves, bringing economic stability. For these reasons, many Koreans prioritize Son-eomneun-nal when choosing moving dates.

From a modern perspective, moving on Son-eomneun-nal provides psychological comfort and creates a positive mindset for new beginnings. Also, since it occurs about 6 days per month, it provides sufficient options when selecting moving dates.

To calculate Son-eomneun-nal, you must first convert solar calendar dates to lunar calendar dates. The lunar calendar is based on moon cycles and differs from the solar calendar. Since the correspondence between lunar and solar calendars changes every year, accurate conversion is necessary.

After confirming the lunar date, check its last digit. If the last digit is 9 or 0, it is Son-eomneun-nal. For example, lunar March 9, 10, 19, 20, 29, and 30 are all Son-eomneun-nal. This calculator automatically converts dates using Korea Astronomy and Space Science Institute (KASI) lunar data to provide accurate Son-eomneun-nal information.

The same rules apply to leap months. Leap months occur approximately once every 2-3 years, and days ending in 9 or 0 during leap months are also considered Son-eomneun-nal. Therefore, when planning a move, it is good to check Son-eomneun-nal for the intended month in advance and select a date that fits your schedule.

If you decide to move on Son-eomneun-nal, thorough preparation in advance is necessary. First, check all Son-eomneun-nal in the month you plan to move and select a date that fits your schedule. Since people generally prefer moving on weekends or holidays, it is even better if Son-eomneun-nal falls on a weekend.

When booking moving companies, Son-eomneun-nal dates are popular and may be fully booked quickly, so it is good to reserve at least 2-3 weeks in advance. Especially during peak moving seasons in January-February and July-August, demand for Son-eomneun-nal increases sharply, requiring even earlier preparation.

On moving day, there is a traditional custom of bringing rice, salt, and red beans into the new home first. This is meant to block bad energy and invite good energy. Also, after moving, it is important to clean every corner of the house and ventilate to create a clean environment.

While Son-eomneun-nal is generally good for moving, there is a traditional belief that days conflicting with one's personal saju (four pillars of destiny) should be avoided. Saju is a destiny concept based on one's birth year, month, day, and time, with each person having different favorable and unfavorable directions and days.

For example, there may be days that conflict with specific zodiac signs. Rat zodiac should avoid horse years or days, and ox zodiac should avoid sheep years or days. Therefore, even if it is Son-eomneun-nal, it is believed better to avoid days conflicting with one's zodiac and choose days that harmonize.

If you want accurate saju analysis, you can consider consulting with fortune-telling cafes or destiny experts. However, from a modern perspective, choosing Son-eomneun-nal does not actually change destiny, and its ceremonial meaning for psychological stability and good beginnings is more significant. Therefore, it is advisable to use it as reference rather than becoming too obsessed.

Son-eomneun-nal is utilized not only for moving but also when starting various important activities. First, when opening or starting a business, choosing Son-eomneun-nal is believed to bring prosperity. Many business owners select Son-eomneun-nal when opening stores or companies to wish for a good start.

Second, Son-eomneun-nal is preferred when starting home repairs or remodeling. Especially when starting large-scale construction, choosing Son-eomneun-nal as the start date is believed to ensure smooth progress and accident-free completion. Third, Son-eomneun-nal may be considered when receiving a new car or purchasing important items.

Fourth, choosing Son-eomneun-nal for important trips or business travel is believed to ensure safe and smooth journeys. Fifth, major life events like weddings or engagements are sometimes scheduled on Son-eomneun-nal. Thus, Son-eomneun-nal is a traditional auspicious day utilized for various beginnings and changes beyond just moving.

Various moving-related customs exist by region in Korea, and the importance of Son-eomneun-nal also varies by area. In Seoul and the metropolitan area, Son-eomneun-nal is considered very important, especially among people aged 30 and above.

In Jeolla Province, there is a custom of sprinkling red beans first when moving, in addition to rice and salt. This is meant to block misfortune and drive away spirits, believed to be more effective when practiced with Son-eomneun-nal. In Gyeongsang Province, there is a custom of preparing a new broom on moving day to sweep every corner of the house.

In Jeju Island, avoiding windy days is considered as important as Son-eomneun-nal, with both weather and Son-eomneun-nal considered together. In Gangwon Province mountain areas, practical weather conditions often take priority over Son-eomneun-nal during snowy winter months. Thus, the utilization of Son-eomneun-nal varies according to regional climate and cultural background.

Son-eomneun-nal still has significant impact in the modern moving market. Moving companies identify Son-eomneun-nal dates in advance each month and prepare personnel and vehicles anticipating concentrated moving requests on those dates. According to statistics, moving reservation rates on Son-eomneun-nal are approximately 40-50% higher compared to weekdays.

Especially when weekends and Son-eomneun-nal coincide, moving costs tend to be 20-30% higher than weekdays. This is a natural phenomenon according to supply and demand principles, and people planning moves should consider this cost difference. Conversely, moving on non-Son-eomneun-nal weekdays can save costs.

When receiving moving estimates, selecting the Son-eomneun-nal option allows you to compare moving company lists and estimates for those dates at a glance. This technological advancement combines traditional beliefs with modern convenience.

When determining contract dates and final payment dates in real estate transactions, Son-eomneun-nal is often considered, and contract schedules are sometimes adjusted to match move-in dates with Son-eomneun-nal. This is particularly prominent during new apartment move-in seasons.

For new apartments, when scheduled move-in dates are announced, many residents check Son-eomneun-nal during that period and plan their move-in accordingly. Some construction companies reflect this demand by setting move-in designation periods to include many Son-eomneun-nal dates. This is consideration to increase resident satisfaction and facilitate smooth move-in processes.

Son-eomneun-nal influence also appears in jeonse (lump-sum deposit) or monthly rent contracts. As lease contract expiration dates approach, contract expiration dates are sometimes adjusted by a few days to match moving dates to new homes with Son-eomneun-nal. This phenomenon is a unique Korean cultural characteristic, forming seasonal and cultural patterns in real estate market supply and demand.
