Marc Diamond asked:

Does the alef in the siman and in "b'alef shel tamuz" represent zero (i.e.) chatzos?

Marc Diamond, Providence, RI

The Kollel replies:

The 'Alef' in the Siman 'Azgi ... ' mentioned in Rashi (with regard to the Tekufah of Nisan) stands for the beginning of the day (i.e. dawn-break), as Rashi himself specifically explains. Shmuel lists the beginning of the day and midnight as two out of the four possible times when the Tekufah of Nisan can fall.
