A day or two will pass between
The Equinox and Equilux –
In Autumn, it is Night who’s keen,
While Day has lingered, still in flux:
So one’s already evened out,
While still the other lags askew.
In Spring, it’s all reversed about
As Day leads by a day or two.
‘Efnniht’ or even-night was the Old English name for the equinox.
