Also – I think it’s a joke. I don’t think there are too many people (if any) who literally say Kinos on the 5th of Iyar. If there are a few people who do, I would imagine they are not people who post in the Coffee Room ( um… actually, maybe they are… in any case, if it happens, I think it’s rare.)
Actually every year posters go up in Meah Shearim with the nusach “x years, how much more can we take?” Whenever I pass by I read a few to get a good laugh., especially those signed “The Rabbanim, Shelita”.
LB: it has nothing to with BHB. Yom Hazikoron for the Israeli Soldiers cannot be on Sunday so it is moved to Monday 5 Iyar and Yom Hatzmaut is moved to Tuesday 6 Iyar.
B – yom beis Monday
H – yom hey Thursday
B – yom beis Monday
It is read Behab. It is starts the first Monday after Pesach to do tshuva for over any averios committed by mistake over Yom Tov. (overindulgence of tayvos) I believe some people fast on those day.
