#When [[Mil]] is given in terms of time, some consider it 18 minutes, some 22.5 minutes, and some 24 minutes. <ref>Shulchan Aruch 459:2 writes that the [[mil]] is 18 minutes. Rama 261:1 agrees. Beiur Halacha 459:2 s.v. Haviy quotes some who consider it 22.5 minutes and others who say that it is 24 minutes.</ref> | #When [[Mil]] is given in terms of time, some consider it 18 minutes, some 22.5 minutes, and some 24 minutes.<ref>Shulchan Aruch O.C. 459:2 writes that the [[mil]] is 18 minutes.

#When [[Mil]] is given in terms of distance it is equal to 2000 [[Amot]]. <ref>Rashi Yoma 67a s.v. shivah and Tosfot Shabbat 34b s.v. safek write that a mil is 2000 amot. Shulchan Aruch 261:2 writes that 3/4 of a [[mil]] is equal to 1500 [[amot]], implying a [[mil]] is 2000 [[amot]]. [http://www.yeshiva.org.il/midrash/shiur.asp?id=15883#3b Rabbi Melamed on yeshiva.org.il] writes that a [[mil]] is 2000 [[amot]].</ref> | * The 18 minute mil emerges from calculating that it is possible to travel 40 mil over 12 hours from netz until shekiya. On an equinox day, there are 720 minutes from sunrise until sunset, yielding a 18 minute mil (720/40=18). This is the opinion of the Rambam Pirush Mishnayot Brachot 1:1, Trumat Hadeshen, and Shulchan Aruch O.C. 459:1. | ||
* The 22.5 minute mil is based on the understanding that a person could walk 40 mil from olot to tzet, with 4 mil from olot until netz and 4 mil from shekiya until tzet, leaving 32 mil from netz until shekiya. Dividing up the 12 hours of the equinox day into 32 equal sections produces a 22.5 minute mil (40-4-4=32; 720/32=22.5). This is the opinion of the Gra 459:1 and Zmanim Khalacha pp. 19-20. | |||
* The 24 minute mil is sourced in the Rambam Korban Pesach 5:8 and Pirush Mishnayot Pesachim 9:1 who holds that a person could travel 15 mil from netz until chatzot and when doubled it emerges a person can travel 30 mil from netz until shekiya. Diving 12 hours into 30 equal parts yields a 24 minute mil (720/30=24).</ref> | |||
