Every year, when the sun sets precisely due west, the spring season begins! This event is called the “Spring Equinox”. The term “equinox” comes from the Latin aequus (equal) and nox (night), because on the equinox, the night and day have approximately equal length. This year, the Spring Equinox occurred on March 20th at 11:14 MDT. This event has been watched for and celebrated by almost all cultures since the beginning of time.
