*Zmanim KHalacha p. 43 quotes Hacham Ovadia as holding that the minutes for Olot do not depend on location but rather shaot zmaniyot. Rabbi Yehuda Levi, author of Zmanim KHalacha, argues with Hacham Ovadia on the same page. He writes that the 72 minutes are not calculated based on the shaot zmaniot and do depend on current location. Rabbi Levi's difficulties stem from the Rambam's language and astronomic calculation. In the Berachot (1:1), Rambam uses a unique Arabic term when referring to alot hashachar, one that is not used in reference to zman Kriyat Shema (Berachot 1:5) or a the time of a mil (Pesachim 3:2). Furthermore, in the winter, it starts to become light earlier than it starts to become light the spring and the fall, despite having shorter shaot zmaniot in the winter; given this reality, it is difficult to justify calculating alot hashachar strictly according to shaot zmaniot. Therefore, Rabbi Levi maintains that alot hashachar's calculation is determined by degrees below the horizon.</ref><ref>In the New York area, this usually takes approximately 40 minutes after sunset at the equinox, and as much as 51 minutes during the summer.</ref> | *Zmanim KHalacha p. 43 quotes Hacham Ovadia as holding that the minutes for Olot do not depend on location but rather shaot zmaniyot.
