Here is my thought.
The equinox is December 21st, this is the point where the amount of darkness and daylight are equal, also known as when a shift from dark to light occurs.
Multiple meanings exist.
So, additionally think mirror as in 12/21 is a mirrored date.
Guess we’ll find out in a matter of days.
Edit: meant solstice not equinox.
It’s 70 here in Texas. It’s February that kills bees here, since they’re already brooding when cold snaps hit.
