Historic Shabbat Hagadol This Year
Read my post last year (including a chart) on how this year (5774) is the last of 4 Aharei Mot leap-year Shabbat Hagadols in a row, which hasn't occurred in almost 250 years! Also, Shabbat Hagadol will not fall out on Parshat Aharei Mot again for another 21 years. Instead, the leap-year Shabbat Hagadols will fall out on Parshat Metzora in the interim.
I wrote last year:
Perhaps, the significance is that we will no longer be cast away as a Metzora, but rather, we will be Aharei Mot - after the period of death and into a new era of life for all mankind. And after 4 times of Aharei Mot in this era of Ikveta Dimshiha, we can finally achieve הנה אנכי שלח לכם את אליה הנביא, which is read on Shabbat Hagadol.May it be so.
