What is the name of the first day of spring and when does it occur?

• A. December Solstice, December 21
• B. Vernal Equinox, March 21
• C. Summer Solstice, June 21
• D. Autumn Equinox, September 21

Answer: (B)

The first day of spring is known as the Vernal Equinox, which occurs around March 21 each year. This day marks the moment when the sun crosses the celestial equator, resulting in nearly equal lengths of day and night. It signifies the transition from winter to spring in the Northern Hemisphere. The Vernal Equinox is significant in many cultures as it represents renewal and rebirth, coinciding with the season when flowers bloom and nature comes back to life after the cold months of winter.

The other choices refer to different celestial events: the December Solstice marks the beginning of winter, the Summer Solstice signifies the start of summer around June 21, and the Autumn Equinox occurs in September, marking the start of fall. Each of these events has its own seasonal significance but does not represent the start of spring as the Vernal Equinox does.
