Czechs have a saying On New Year’s Day: “Jak na nový rok, tak po celý rok” which means something like “What you do on New Year’s day, you’ll do every day the next year.” That means that doing any work whatsoever is said to be bad luck. No cleaning the house or washing the dishes and really whatever you do, if you’re at all superstitious, don’t hang up laundry or you could experience personal unhappiness in the New Year.
