Sorry dear Doves. My reasoning was incorrect in adding 11 days to get 2550 days. One needs to subtract 11 days from before Yom Kippur 2017 on 10-1 to 2. The date would be Elul 29, the last day of Elul and the day before the Feast of Trumpets in 2017. So the time frame of 2550 days would have begun on Elul 29, 2017 in order to complete 2550 days as of Yom Kippur 2024 on the Torah Calendar. I regret any confusion.
 
With Love and Shalom,
Jean
