The Dragon Boat Day is almost here and the month of June in which it takes place is also known as the Horse month in China, The so-called horse hour in Chinese astrology is from 11:00 AM to 13:00 PM. It is well known among believers that you will be lucky for the coming year if you can make an egg standing up during Horse hour on the Dragon Boat Day.

Parents like to let their children try to make the egg stand up on the Dragon Boat Day. The stand up egg competition will be held at noon in several places. It is said that it will be easier to make an egg stand up at noon. Many have aimlessly tried on cheat on the ground, in order to win the competition.

Some have often wondered if there is a scientific explanation for this. The egg can standup easily because the Dragon Boat Day is close to the summer solstice, which is the longest day of the year. The summer solstice occurs when the Earth's axis tilts the most toward the sun, causing the sun to be farthest north at noon. Sun reaches to the Tropic of Cancer in the northern hemisphere on the day of summer solstice. Before sun travels back to the southern hemisphere, it seems as if the sun stands still. When the gravitation between sun and earth are pulled towards each other to the most, the egg can stand up easier.

What makes this particular boat day special is that the Dragon Boat Day is not close to the summer solstice every year. Because of the lunar leap months however, the Dragon Boat Day usually is close to summer solstice every three years.
