September: Spring Moon

September is National Heritage Month and September 24 is Heritage Day!

During September, the Sun moves from north to south on the celestial sphere, crossing the celestial equator on the date of the equinox, which is around September 22.

On that day, the lengths of day and night are approximately the same. After that date, the days become longer than the nights, and we’re heading into summer!

This date is known in the southern hemisphere as the spring equinox and is considered by astronomers as the start of spring. In popular culture, however, September 01 is usually thought of as Spring Day.

Seasons are somewhat difficult to pin down, and depending on who you ask, start on different dates and last for different periods. Regardless of what the actual date is, spring is seen in many cultures as a time of rebirth and regeneration. After good winter rains this is also the time when Namaqualand and the Northern Cape put on their breathtaking display of flowers which produces the seed store for the next generation of plants.

In agriculture this was and still is generally the time of ploughing, preparing gardens and sowing; the time when the first green grass begins to show, the cattle become fat and there is a promise of summer and a time of plenty to come.

The second Full Moon in September is the Blue Crane Moon.
