With the sun rising higher, the days grow longer, marking the arrival of spring. The spring equinox occurs when the sun crosses the celestial equator, moving from the Southern Hemisphere to the Northern Hemisphere. Traditionally, spring is considered to begin on March 21. However, astronomers and calendar makers now agree that spring officially commences on March 20 across all time zones in North America. This event signals the true start of the season, bringing with it the beauty and symbolism of spring blooms.
