The spring equinox, also known as the vernal equinox, occurs around March 20 or 21 each year when the sun crosses the celestial equator, resulting in nearly equal durations of day and night. To calculate the exact date, astronomers use algorithms that account for the Earth's orbit and axial tilt, which can slightly vary the date each year. The equinox marks the moment when the sun is directly above the equator, and can be determined using astronomical software or calculations based on the position of the sun and Earth.
