I've never seen this written about.
How do you mentally visualize the calendar year?
In a long straight line with little flags for the season and/or birthdays and/or festivals?
Like a circle ending at New Year's?
I see it as an ovoid.
Something like this:
But unfortunately (for me)backwards as my Imbolc is on the left and down around to Samhain on the upper right before the year ends.
Today is the vernal equinox where day and night times are exactly the same length.
And Ostara - upon which the tradition of Easter is based - orginated with the goddesses. Like most festivals on the religious calendars, prominent female personae were erased or placed in secondary roles.
I remember seeing fertility goddesses in the stone carvings of ancient Irish churches. I imagine they were carved to appease the goddess worshipping "pagans" in an attempt to convert them to Christianity.
What an enormous body of knowledge and rituals and healing we have lost.
Mother Earth is not pleased.
