1, Tanabata is the seventh day of the seventh lunar month every year, which is a traditional festival in China. Valentine's Day in China, also known as George's Day, George's Day or Chinese Valentine's Day, is also called "Valentine's Day in China".
2. Because of the legend of Cowherd and Weaver Girl, Tanabata is endowed with the meaning of love, and Chinese Valentine's Day has become the most romantic day in traditional festivals in China, which is recognized by more and more young people.
The legend is of course beautiful, but according to the records of ancient astronomy, there are indeed two stars, Altair and Vega. The ancient astronomical calendar took the intersection of these two stars as the day when the sky changed. This day also happens to be the seventh day of the seventh lunar month, which is in line with the very auspicious number considered by ancient metaphysics, so the seventh day of the seventh lunar month is designated as Qixi.
So much for the date of July 7th.
