Spring is seen as a time of growth, renewal, of new life (both plant and animal) being born. The term is also used more generally as a metaphor for the start of better times. The word “equinox” derives from the Latin words meaning “equal night” and refers to the time when the sun crosses the equator. At such times, day and night are everywhere of nearly equal length everywhere in the world. In the northern hemisphere the March equinox marks the start of spring and has long been celebrated as a time of rebirth.
Many cultures and religions celebrate or observe holidays and festivals around the time of the March equinox, such as the Easter holiday period. The astronomical Persian calendar begins its New Year on the day when the March equinox occurs.
