Some Calendar Stuff
R' Ari Enkin at Hirhurim tells us that we hadn't had a Friday 10th of Tevet in 10 years (5761). He mentions the years that we will next be commemorating Asara BeTevet on a Friday as being: 5771, 5774, 5781, 5784, 5785, 5795, 5798.
There is another rare occurrance that happens about the same time of year: i.e. A Shabbat Parshat Miketz that does NOT fall out on Hanukka. This too last happened 10 years ago (5761), and this will not happen again for another 10 years (5781). 5781 is on the list for a Friday Asara BeTevet.
So, I was wondering if the list of Shabbat Parshat Mikketz not falling on Hanukka is a subset of the list of Friday Asara BeTevets. This theory seems to be correct. See the table below.
May we soon not have to fast on Asara BeTevet any longer.
|Year||Asara BeTevet Friday||Shabbat Parshat Miketz NOT on Hanukka|
