Why Is It Bad Luck to Clean on New Year’s Day?

The idea goes back to an old Chinese belief that sweeping or cleaning on the first day of a new year physically sweeps the good luck right back out the door with the dust. Whatever fortune walked into your house at midnight is treated as something fragile and new, and a broom moving across the floor on January 1st risks pushing it straight back out before it has a chance to settle in.

It sounds like a convenient excuse to skip the chores, and plenty of people treat it that way. But the superstition has real staying power, showing up across several unrelated cultures, and it’s specific enough that it comes with its own rules: clean everything you want before the year turns over, then leave the broom alone once it has.

The Logic Behind “Sweeping Away” Good Fortune

The core idea is pretty literal. Good luck is imagined as something that enters a clean, welcoming home right as the new year begins, almost like a guest arriving. Sweep the floor while that luck is still settling in, and you risk sweeping it straight back out with the dirt. Take garbage or old belongings out of the house on that same day, and you’re symbolically hauling prosperity out along with them.

This is why the timing matters so much in places where the belief is taken seriously. Cleaning itself isn’t the problem. Cleaning on the wrong day is.

Where the Superstition Actually Comes From

This tradition traces most directly to Chinese Lunar New Year customs. In the lead-up to the new year, usually about ten days before it starts, households do a genuinely thorough deep clean known as “sweeping of the grounds.” Every corner gets scrubbed, swept, and aired out, with the goal of physically removing whatever bad luck or misfortune built up over the previous year before the new one arrives.

Once that deep clean is done and the new year actually begins, the broom gets put away. Sweeping, mopping, taking out the trash, even washing your hair, are all avoided for the first day or two of the celebration, since any of them risks undoing the work of clearing the way for good fortune. The logic is almost the opposite of how most people think about a “fresh start”: the cleaning has to happen before the reset, not on the day of it.

The Laundry Version Gets Even Darker

Doing laundry carries its own specific version of the superstition, and it’s a noticeably harsher one. Washing clothes on New Year’s Day is said to risk washing away good fortune for the entire year ahead, the same basic mechanism as sweeping, just applied to a washing machine instead of a broom.

Some tellings of the superstition go further than that. Washing clothes on New Year’s Day has also been linked to the darker warning that doing so could “wash away a loved one,” meaning someone close to you might not make it through the coming year. It’s a much heavier claim than misplaced luck, and it’s part of why the laundry-specific version of this superstition tends to get repeated even by people who’d otherwise shrug off the cleaning taboo entirely.

It’s Not Just a Chinese Tradition Anymore

The belief has spread well past its origins and shown up, in slightly different forms, in a number of other cultures. Similar ideas about clearing clutter and cleaning before the new year, rather than during it, appear in Filipino New Year traditions and in some African American folk customs as well. The specific mechanics shift a little from place to place, but the underlying shape stays consistent: do the deep clean ahead of time, then leave things alone once the calendar actually turns.

That overlap across unrelated cultures is part of what makes the superstition interesting. It’s the same instinct that shows up in a lot of New Year traditions worldwide, treating January 1st as a kind of blank, fragile page that hasn’t been written on yet, and any disruptive action taken on it, whether that’s sweeping, washing, or something else entirely, is thought to shape the whole year that follows.

When You’re Actually Supposed to Clean

If the superstition is going to be followed properly, the timing is the whole point. The deep clean happens beforehand, ideally finished by New Year’s Eve, so the home is already spotless when midnight hits. That’s when floors get mopped, clutter gets cleared out, and anything that’s been piling up since before the holidays gets dealt with.

Once the new year actually starts, the advice is simple: leave it alone. Skip sweeping, skip laundry, skip taking the trash out, at least for the first day, and in some traditions the first several days. January 2nd is generally treated as the point where cleaning becomes safe again.

Should You Actually Skip It?

Nobody’s making the case that a genuinely dirty broom controls your finances for the next twelve months. But there’s something to be said for the ritual itself, separate from whether the superstition holds any literal truth. Doing a real deep clean before the year ends gives the new year an actual clean slate to start from, and building in a day where you’re not scrubbing anything, just resting and enjoying the holiday instead, isn’t a bad habit regardless of what you believe about luck.

If skipping the vacuum on January 1st gives you one more excuse to relax instead of catching up on chores, that’s a tradition worth keeping around either way.
