Korean movers strap a crane to the truck because, for most floors, loading furniture straight through a window is faster and cheaper than booking a building’s elevator — though as I found out, that math flips once you’re high enough in the building — and a “lucky” moving day, son eomneun nal (손없는 날), typically costs 10 to 30 percent more than an ordinary weekday, depending on the load and the company.
The Night We Argued Over a Lunar Calendar, Not a Moving Date
Our jeonse (전세, Korea’s lump-sum deposit lease) was up for its two-year renewal this spring — the same renewal cycle I wrote about a few weeks ago, when the government’s jeonse insurance subsidy form quietly excluded foreigners from a program citizens get automatically. This time our landlord wanted the unit back, so we had about six weeks to find a new place, sign, and move our three-person household. The night we sat down to actually pick a date, I pulled up a lunar calendar site on my laptop to check which days were son eomneun nal (손없는 날, son-eomneun-nal, literally “the day without son” — more on what that means below) before calling a single moving company.
My wife looked at me like I’d lost it. She’s about as ENFP as it gets, and to her the whole idea of picking a moving date around which evil spirits are theoretically off duty landed somewhere between charming and ridiculous. “Just pick whatever Saturday works,” she said. I build systems for a living. “Whatever works” isn’t really in my vocabulary when there’s a number I can pull instead — I wanted the actual price difference before I committed to a date, not a vibe. So I did what I always do: I got quotes for both a regular weekday and the nearest son eomneun nal, and let the numbers decide.
What Is “Son Eomneun Nal,” and Why Do Koreans Still Pick Moving Days by the Lunar Calendar?
Son eomneun nal falls on lunar calendar dates ending in 9 or 0 — the 9th, 10th, 19th, 20th, 29th, and 30th of each lunar month. In the folk belief behind it, malicious spirits called son (손, not the English word “son” — closer to a mischievous or harmful force) patrol the earth in a rotating four-direction cycle for most of the month, and interfere with anything new started in whichever direction they’re occupying: a move, a wedding, opening a shop. On the days ending in 9 or 0, tradition says all four son retreat to heaven at once, leaving nobody around to jinx a fresh start.
Almost nobody I know treats this as literal spiritual protection, my wife least of all. But son eomneun nal has survived as a default scheduling convention anyway. Moving companies advertise around it, families request it by name even when they’d call themselves non-superstitious, and enough of the country books around those dates that it has become a genuine pricing event — not just a folk curiosity nobody acts on.
How Much Extra Does a “Lucky” Moving Day Actually Cost?
The premium is real enough that moving companies quote it as a line item. Industry pricing guides put the standard markup at 10 to 30 percent over a comparable weekday, so a basic move priced around ₩1,000,000 becomes ₩1,100,000 to ₩1,300,000 on a lucky date, and a modest one-ton pojang-isa (포장이사, po-jang-i-sa, literally “packed move” — Korea’s full-service option where the crew packs, wraps, and unpacks everything) that runs about ₩500,000 on a regular day picks up roughly ₩100,000, about 20 percent, when it lands on son eomneun nal.
I called three pojang-isa companies for real quotes on our own load — a two-bedroom apartment, one truck, nothing oversized — once for a regular Tuesday and once for the son eomneun nal three days later. The spread wasn’t small, and it wasn’t consistent between companies either.
| Mover | Regular Tuesday | Son Eomneun Nal | Premium |
|---|---|---|---|
| Company A | ₩950,000 | ₩1,150,000 | +21% |
| Company B | ₩880,000 | ₩1,140,000 | +30% |
| Company C | ₩990,000 | ₩1,030,000 | +4% |
Company C barely moved its price at all, which told me the son eomneun nal markup isn’t a fixed tax — it’s demand pricing, and it swings by how booked a given company already is for that date. We took Company C’s regular Tuesday slot, saving roughly ₩150,000 to ₩200,000 against any lucky-day quote we’d gotten, and nothing about the move went any worse for skipping the “auspicious” date.
Why Does a Crane Truck Show Up Instead of Using the Elevator?
The truck with the extending arm and a metal platform on the end is a sadari-cha (사다리차, sa-da-ri-cha, literally “ladder car” — a mobile lift built specifically for moving day). Instead of carrying furniture down a hallway and squeezing it into a passenger elevator, the crew loads everything onto the platform at ground level and the arm lifts it straight up to your window or balcony. It looks dramatic to anyone who hasn’t lived here, but it solves three problems at once: Korean apartment elevators are often too narrow or short for a full-size sofa or wardrobe to fit at any angle, every other unit in the building needs that same elevator on the same day, and building management typically requires the crew to pad the elevator walls and reserve a time slot in advance before a single box moves. A sadari-cha skips all of that by never touching the shared elevator.
The price scales sharply with floor, since a taller lift needs a bigger truck and more setup time.
| Floor | Sadari-cha cost (5-ton truck) |
|---|---|
| 2nd–5th floor | ≈ ₩150,000 |
| 10th–11th floor | ≈ ₩180,000 |
| 20th floor | ≈ ₩280,000 |
| 24th floor | ≈ ₩400,000 |
Our new place is on the 12th floor, just past that 10th–11th floor bracket, and the sadari-cha line item on our quote came in around ₩185,000 — something I’d never once seen on a moving estimate before we lived here, and something my wife had never questioned either, until I made her watch the arm extend past our balcony on move-in day.
Can the Elevator Actually Cost More Than the Crane?
Not the way I expected going in — it’s actually the sadari-cha that gets more expensive at extreme height, not the elevator, and the crossover happens right around the floor range where buildings start requiring specialized lift equipment. A sadari-cha’s price climbs with every additional floor because a taller lift needs a bigger truck and more setup time, and past roughly the 17th or 18th floor, crews switch to a specialized high-rise unit that costs even more to book. The building’s elevator usage fee doesn’t scale the same way — it’s a flat rate the building itself sets, typically ₩50,000 to ₩100,000 and up to ₩200,000 at a pricier high-rise, whether you’re moving out of the 6th floor or the 26th. Stretch the sadari-cha’s climbing rate far enough against the elevator’s flat one and the two lines eventually cross.
That ₩280,000 line for the 20th floor in the table above is priced per location, not per move — use the sadari-cha to load at your old building and again to unload at the new one, and you’re paying it twice, for a real total closer to ₩560,000. A 2026 moving-cost breakdown running that same 20th-floor comparison put the savings from switching to the elevator at roughly ₩250,000, once the flat usage fee and the extra labor for padding the cabin and running repeat trips are factored in. Past that crossover point, the sadari-cha stops being the efficient option — it’s the elevator, reservation hassle and all, that ends up being the cheaper one on paper.
What Do You Need to Do in the 14 Days After You Move?
Once the truck is unloaded, there’s a clock running. Every resident of Korea — foreign nationals included — has 14 days from move-in to file jeonip-singo (전입신고, jeon-ip-sin-go, literally “move-in report”) at the local community center or through the government’s online portal, updating your registered address for everything from national health insurance to your kid’s school zoning. Miss the window and paperwork tied to your old address — tax notices, insurance correspondence, eventually the jeonse deposit return itself — keeps assuming you still live there.
On timing the move itself: a full-service pojang-isa is worth booking two to four weeks ahead, especially around a son eomneun nal or the start and end of a month, when lease turnovers stack up and slots fill first. If you don’t need the full pack-and-unpack crew, a kol-baen (콜밴, “call van” — a small van with just a driver, no packing service) starts around ₩100,000 for a light, one-person load, while full pojang-isa service can run past ₩1,000,000 depending on distance and volume. Budget for roughly a ten-times gap between those two options, not “a bit more.”
If I’m giving my own read on it after actually pricing all of this out: I wouldn’t pay a 20–30 percent premium to dodge mythical evil spirits, but I’d absolutely pay attention to which floor I’m moving into before I pay attention to which day it is — floor number moved our estimate by more money than the lunar calendar ever did. My wife still thinks I overthink these things. She’s not wrong. But the spreadsheet saved us close to ₩200,000, so I’ll take it.
