Dou refers to noon; the sun's yellow meridian is 90°; it intersects the festival on June 21-22 of the Gregorian calendar. On the summer solstice, the sun's direct position on the ground reaches the northernmost point of the year, almost directly to the Tropic of Cancer, when the daytime across the northern hemisphere reaches the longest of the year. For the Tropic of Cancer and areas north of the Tropic of Cancer, the summer solstice is also the day of the year when the height of the sun at noon is the highest.

For regions of China located north of the Tropic of Cancer, the height of the sun at noon begins to decrease day by day after the summer solstice; for regions of China located south of the Tropic of Cancer, the height of the sun at noon begins to decrease day by day after the summer solstice when the sun is again in direct sunlight via the southward return.
