And the year following this year, we should live and be well, is a 5S7 model, also with RH on Thurssay, Pesach on Shabbat.
The last time we had Rosh haShono 4 out of 5 years on Thursday & Friday, was 98 years ago, but next time shall be in 24 years followed by 27 years after that.
From 2070 to 2079 it shall not happen for 10 years straight. That shall be 1st time in 521 years, skipping 10 years straight.
But please bear in mind:- For working purposes:- It is much harder when all the Chaggim come out on a Tuesday & Wednesday, than having them come out on a Thursday 7 Friday.
