At the same time as in the Northern Hemisphere The equinoxes are around March 21 and September 22 each year (the calender date shift slightly due to the uneven number of days in a year - that's why we have leap years almost every fourth year- to bring the equinox es and solstices back to the same calender date).

Why does the vernal equinox in Johannesburg occur in September?
The vernal equinox in the Southern Hemisphere occurs around September because this is when the tilt of the Earth's axis is inclined neither away from nor towards the Sun, resulting in almost equal lengths of day and night. In Johannesburg specifically, the vernal equinox occurs in September due to its location south of the equator.
Is the autumnal equinox at the same time every year?
No, it moves slightly forwards and backwards in time, but within a 12 hour period due to the Earth's wobble that is separate from the Procession of the Earth's poles. So in some years it can occur on the 20th of September, and other years on the 21st.
How are march and September equinoxes similar?
The March and September equinoxes are similar in that both mark the points in the year when day and night are approximately equal in length across the globe. They occur when the sun is directly above the equator, resulting in this balance of light. Additionally, both equinoxes signify the transition between seasons: the March equinox heralds the arrival of spring in the Northern Hemisphere and autumn in the Southern Hemisphere, while the September equinox marks the onset of autumn in the Northern Hemisphere and spring in the Southern Hemisphere.
What happens when the sun reaches the equinox?
During the equinox, the sun is directly above the equator, resulting in nearly equal lengths of day and night all over the world. This marks the start of spring in the northern hemisphere and autumn in the southern hemisphere. The equinoxes occur twice a year, typically around March 20th and September 23rd.
