I noticed that the only times that parshat Matot and Mas'ei are read separately outside Israel is during a leap year when the first day of the previous Rosh Hashannah occurred on Thursday. This would mean that the 1st day of Pesach was on either Sunday or Tuesday.
This year and the previous 3 leap years (5765, 5768 and 5771) all had Matot and Mas'ei separate. So including this year, there were 4 consecutive leap years when this occurred.
Has this pattern ever occurred previously since the current Judaic calendar was established? Is there any forseeable repeat of this pattern?
