September Equinox
22 September 2021 19:21 UTC
there are two Equinoxes every year . . .
one in September and one in March
the September Equinox is the moment the Sun 'appears to cross' the celestial equator from North to South
we know . . .
the earth’s rotation causes day and night
the earth’s revolution creates the seasons
and the earth’s tilt of approximately 23.5 degrees creates Opposite Seasons
so, during the the following months
this tilt will cause
the South to face more directly towards the Sun
and the North to face further away from the Sun

the time at which the Sun was directly above the celestial equator
note the terminator is a vertical line straight down
Equinox on a Spinning Earth shows seasonal changes for an entire year in twelve seconds
the way of heaven is like the flexing of a bow
the high it presses down
the low it raises
from those with a surplus it takes away
to those without enough it adds on
therefore the way of heaven
is to reduce the excessive and increase the insufficient

may you have a wonderful year
