The traditional Chinese lunar calendar divides a year into 24 solar terms. The Spring Equinox (Chinese: 春分), as the fourth term of the year starts on March 21 and ends on April 4 this year in 2019.The Spring Equinox signals the equal length of the day and night time. On the day of the Spring Equinox, sun is directly above the equator. After the equinox, the sun moves northwards, resulting in gradually longer day time in the Northern Hemisphere and longer night in the Southern Hemisphere.
Swallows fly north
The ancient Chinese people divided the fifteen days of the Spring Equinox into three “hou’s,” or five-day parts. As the old saying goes, swallows fly back to the North in the firsthou; thunder cracks the sky in the secondhou; lightning occurs frequently in the third hou, which vividly reveals the climate feature during the Spring Equinox.
