A person passed away Bein Hashmoshos, when is the Yahrtzeit and which date is put on the Matzeivah? Thank you
Answer:
With regards to kaddish and the amud, if possible both days should be kept. Otherwise, Rav Moshe Feinstein ruled that the later day should be observed, being for the entirety of the first day the niftar was still alive.
