CCTV News: February 12 is the Lantern Festival. This year's Lantern Festival coincides with the "Fifteenth Moon" and if the weather is sunny, a bright moon will hang high in the night sky.

The 15th moon is round and the 15th round is round at 21:53 on February 12th

According to popular science experts from the Beijing Planetarium, on February 12th, the Lantern Festival on the 15th day of the first lunar month, at about 21:53 Beijing time that day, the three celestial bodies of the moon, the earth and the sun are arranged in an approximately straight line, and the moon will present the most perfect state to the earth. This is also the second year of the fifteenth day of the first lunar month starting from 2024.

According to Cao Jun, an associate research librarian at the Beijing Planetarium, this time it happened to be three consecutive Lantern Festivals, and the moon was fifteen rounds, but after that, it may be on another date for a long time.

There is a saying on the Internet: If you miss the full moon of the Lantern Festival in 2025 and 2026, you will have to wait for the next decade to see the "fifteenth moon, fifteenth moon" during the Lantern Festival. In this regard, Cao Jun explained that this ten-year cycle is just a statistical coincidence, and the change in the time of looking at the moon actually has its own rules.

Cao Jun said that this so-called 10-year cycle does not have a major regularity, it just happens to make up this number, but if you look at when the full moon appears in a row every month, it is actually a cycle that takes about 14 months.
