No he didn't.OK Drucker has brought us through why some think that Spring starts in the first week of what is now February, can you explain why it is you think Spring doesn't start until March. And is it always March 1st btw, or is it the first week of March or what? Genuinely interested in hearing both sides of this and am yet to be convinced on the March thing. Thanks in advance.
As explained in the post you quoted the concept of Spring was superimposed on the pagan festival of Imbolic way later.
Imbolic isn't the same as Spring.
There are multiple posts explaining this to you over the years on this very thread.
However you can't admit you're wrong which is why we go over it again with you every fucking year.
