The summer solstice is coming, I wish you happiness and warmth, smooth work opportunities, and a happy smile

The summer solstice is one of the twenty-four solar terms on June 20, or 21, or 22 on the Gregorian calendar. On the day of the summer solstice, the sun runs to 90 degrees of the yellow longitude, and the position of the sun directly hitting the ground reaches the northernmost point of the year, almost directly hitting the Tropic of Cancer. At this time, the daytime in the northern hemisphere reaches the longest year.
