What Beginning of Spring marks
The season behind the name
Start of Spring opens the traditional spring season, turning the agricultural calendar toward a new cycle of growth.
These names grew from seasonal observation and farming practice. They describe a traditional seasonal sequence, not a weather forecast for every region.
Beginning of Spring begins at the instant the Sun reaches 315 degrees of apparent ecliptic longitude. It is one of 24 equal 15-degree divisions of the solar year, so its Gregorian position changes only slightly from year to year.
As a jie term, Beginning of Spring opens solar branch month 1, associated with the Tiger (寅) branch. This is an almanac solar-month boundary, not the first day of a lunar month.
The time is shown in China Standard Time (UTC+8). A reader west or east of that zone may see the same instant fall on a different local civil date.
