When do we start saying ותן טל ומטר לברכה?
In EY we started saying it tonight on ז' חשון. Outside of EY we start 60 days after the tekufa, which today is assumed to be December 4th or 5th. This calculation has always bothered me greatly for the following reason. If you look at the Beis Yosef (and all the other poskim from that time)you will see that he writes that 60 days after the tekufa was November 22. However, the later acharonim all say, that was based on the Julian calendar, but now, since the world changed to the Gregorian calendar which meant that when they changed they skipped 12 days, we start on December 4th. I don't know much about these issues, but this seems very difficult to me. Those 12 days were a 1 time adjustment because the Julian calendar was not accurate enough, if so why should the 60 days from the tekufa change (it was a 1 time thing to fix the calendar drift)? Isn't the tekufa still around September 21st? In short, the Gregorian calendar just fixed the drift of the Julian calendar by skipping 12 days (once) and changing the leap year rules, why should that change when 60 days from the tekufa is?
I would really appreciate an answer or a pointer to someone who discusses this issue, this has bothered me for a long time.
