Can one read the Megila after Plag Hamincha on Leil Purim and then again after Plag on Purim day? Maybe it is תרתי דסתרי because when reading the first time he is saying that it is already night after Plag and the next day he is saying that it is still daytime??
It should go viral....
While on the topic, מענין לענין שלא באותו הענין - If someone read the Megila after Amud Haschachar thinking it was still night, is he yotzei the daytime obligation? There are various ra-ayos. I had one BS"D from the Sfas Emes quoted in the afore-linked [new word, invented right here on Mevakesh!!:-)] shiur and another from the Birkei Yosef. I sent it to a certain Gaon Shlita for his appraisal. On the edge of my seat....
