Leap Month Mechanism - To align the lunar calendar with the solar calendar, ancient astronomers introduced leap months, adding 7 leap months in a 19-year cycle [6]. - The placement of leap months is determined by the 24 solar terms, which divide the Earth's orbit into 24 segments [6]. Current Leap Month Details - In 2023, the leap month is designated as "leap June," occurring from July 25 to August 22, with only one solar term (Liqiu) present in this period [6]. - The leap month has 29 days, and the absence of a solar term in the preceding month led to its designation as a leap month [6]. Frequency of Leap Months - This century will see a total of six occurrences of leap June, specifically in the years 2017, 2025, 2036, 2055, 2074, and 2093 [7].
