# According to Sepharadim, Alot HaShachar is 72 minutes before sunrise.<ref> Yalkut Yosef, Kitzur Shulchan Aruch, Siman 58, Seif 3. </ref> These minutes are proportional to the length of the day,<ref> Yalkut Yosef, Pesuke DeZimra and Keriat Shema, pages 432-433 based on Rambam, Perush Mishnayot, Masechet Berachot, Perek 1.</ref> and do not depend on current location.<ref>Zmanim KHalacha, page 43, quoting Hacham Ovadia zt"l.

Hence, 72 minutes would be 1.2 multiplied by the day's shaa zmanit. 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 first mishna of masechet berachot, Rambam uses a unique Arabic term when referring to alot hashachar, one that is not used in reference to Kriyat Shema (Berachot 1:5) or 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> | ||
