– Q. I know that one should not answer when asked by a friend when it is already time to count the Omer what day it is, since when answering it would be as if one counted and would loose the possibility of reciting a bracha. Can one just show with the fingers of the hand how many days it is?
A. Mishna Berura (489: 20) rules that even if one answered with a number without saying “Today is” followed by the number he is still permitted to recite the bracha, obviously the same applies when one just show with the fingers of the hand how many days it is. See following questions.
