Reb Eliezer
You just wrote above
“.We start counting months from Nissan and not from Tishri whereas Jewish years are counted from Tishri and not from Nissan”
Thus you just contradicted yourself and now you changed your mind and admitted to Hashem that yes we do count Jewish years from Tishrei and that’s when it becomes a new year.
Want to explain yourself or just confess to Hashem for all Hashems direct shocking wake up calls sent down straight to klal yisroel to prevent future tragic wake up calls from being needed ahead if we would just stop living in denial and start facing reality already
