Dog days refer to three consecutive periods of high temperature in summer, usually in the summer of the lunar calendar. In China, the dog days are generally divided into three days: the beginning, the middle and the end.
The initial stage is usually from early July to mid-July, the intermediate stage is from mid-July to the end of the decade, and the final stage is from early August to mid-August. The total number of days added together in these three time periods is not fixed, and the length of dog days may be different every year.
The specific number of days in dog days is calculated according to the orbit of the sun and the seasonal changes of the earth. They are usually determined according to calendar and astronomical calculations, so the dog days may change every year. If you want to know the number of dog days in a specific year, you can refer to the relevant data released by the meteorological observatory or meteorological department.
Precautions for geomantic omen in dog days
1, keep the air circulating: it is hot in dog days, which easily leads to the air not circulating, resulting in sultry discomfort. Therefore, it is very important to keep indoor air circulation. You can open windows for ventilation, and use fans or air conditioners to increase air circulation.
2. Humidity control: The humidity is high in summer, which is easy to breed bacteria and mold, affecting the living environment and health. Keeping the indoor humidity suitable and cleaning and dehumidifying regularly can reduce the adverse effects of humidity on geomantic omen.
3. Pay attention to the movement of water: water is of great significance in Feng Shui. Water can be added properly in dog days, such as placing a pool, fountain or fish tank, giving people a cool and comfortable feeling. However, it is necessary to avoid water accumulation or long-term stagnant water, so as not to cause adverse feng shui effects.
