Longer days and new beginnings: The Equinox’s impact on time and spiritual renewal
Following the equinox, the Northern Hemisphere will experience progressively longer daylight hours until the summer solstice in June. For example, cities like Atlanta will gain approximately two hours and sixteen minutes of daylight between March 20 and June 20.
The spring equinox also marks the beginning of the astrological new year, as the Sun enters the sign of Aries. This period is considered a time of renewal, encouraging people to set new intentions for the season. Many celebrate in unique ways, from meditating under the sun to planting seeds symbolizing future goals.
Cultural celebrations and gardening traditions mark the arrival of Spring
Additionally, the equinox coincides with the celebration of Nowruz, the Persian New Year, a tradition over 3,000 years old that welcomes the arrival of spring. In areas like the San Francisco Bay, cultural events, including art exhibitions, concerts, and community gatherings, commemorate this special occasion.
For gardening enthusiasts, the arrival of spring is the perfect time to start planting vegetables like lettuce, radishes, and Swiss chard. Although the soil may still be cold and damp, starting seedlings in greenhouses is recommended to ensure a successful summer harvest.
