Is there any basis for the old saying "Don't build a house in May and don't move in June"?

It is an old saying, so the meaning it embodies is applicable in ancient times, and there must be some basis.

For modern us, building a house is always under construction, and moving is always moving. It is difficult to understand the relationship between building and moving a house and time. And the house is reinforced concrete, the main components are sand, stone, cement and steel bars. The foundation can go deep into the ground 10 meter or more, and the solid house can resist the earthquake of magnitude 8, and the building is rain or shine. Modern machinery can lift heavy objects to the top floor, with convenient transportation, quick construction and workers' safety measures in place.

On the other hand, in ancient times, what happened when they built houses?

Most ancient houses were adobe houses, made of loess, Gaza and plants, and then the roofs were covered with tiles. Every process must be manufactured, transported and built by hand, so safety measures are worrying.

These difficulties are secondary, so why build houses by month and day?

Think about the brick wall mixed with soil and plants, can it solidify as fast as the concrete now? No, it lags far behind the speed of concrete solidification. Moreover, after solidification, it was washed by heavy rain, and the concrete was intact. The yellow mud wall can cross the river like a clay idol, and it often takes months to build a house. If you start building a house in May, it will be in the hot summer when it is halfway built, with plenty of rainfall and heavy rain. Workers are likely to get sick from heatstroke when building a house, and the house can't stand the baptism of heavy rain. Therefore, it makes sense not to build a house in May.

It's the same if you don't move in June In ancient times, moving was not like now. Now, a truck will arrive at a new home. Have a professional cleaning team, or even if there is no professional cleaning, clean at home and take various measures to prevent heat, such as turning on the air conditioner, turning on the fan, drinking summer drinks and so on. How convenient. In ancient times, transportation was inconvenient and backward. When moving, it was mules, cows and horses. Baggage can be discharged from one place to another, which is not bad, but it is far away. After walking for a few days and months, the old people and children struggled on the road for so long, sick and hot. If there is heavy rain, it depends on luck.

Does it make sense for the ancients not to build houses in May and not to move in June?
