Sunday holiday?
Nimrod dies and becomes the sun - the sun god
Ishtar his wife becomes mysteriously pregnant, in an immaculate conception
Tamuz is born on the 25th of December, as a result, to Ishtar the moon goddess
9 months before we have the miraculous conception, so -
On the first Sunday after the 1st full moon following the equinox - eggs, rabbits, etc - for the fertility queen - Ishtar the moon goddess.
We are however counselled to use these times (in March/April & December [with the pagan/Christian blending]) while people are at least thinking for a moment of Christ (we have HIM every moment all year) to “be ready always to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear” (as Peter advises us)...
The passover even sometimes lines up with Easter, but it is always Pagan it is about the sun - equinox & Sunday and the moon - full.
