But when does spring actually start?

There’s also the astronomical or “nature’s calendar” version of spring:

  • The spring (September) equinox in South Africa usually falls on 22 or 23 September , when day and night are roughly the same length.
  • In 2026, for example, the equinox is listed as 22 September 2026.

Why 1 September is still called Spring Day

  • South Africans adopted 1 September as the start of spring largely for simplicity and tradition , following the meteorological habit of starting seasons on the first of certain months.
  • Over time it became a cultural moment: flower outings, “Spring Day” office dress-ups, and promotions all cluster around 1 September.

An example: an article explains that while the real seasonal change is tied to the equinox, South Africans still cheerfully celebrate “Spring Day” on 1 September out of habit and convenience.
