Tzitzit: Difference between revisions

# The earliest time to say a bracha on Tzitzit is from the time period that there is enough natural light to be able to distinguish between the white and blue strands within a clump of Tzitzit.<ref>Shulchan Aruch 18:3</ref> This time period is also known as the time when one is able to recognize an acquaintance from a distance of 4 cubits. Both descriptions are equivalent and commonly referred to as [http://halachipedia.com/index.php?title=Reference_of_Measurements_in_Halacha#MeSheyakir Misheyakir]. There is a wide range of opinions on precisely what time [http://halachipedia.com/index.php?title=Reference_of_Measurements_in_Halacha#MeSheyakir Misheyakir] occurs on a perfect day.<ref>Meaning that there is exactly 12 daylight hours and every seasonal hour consists of 60 minutes.</ref>  In Jerusalem it is considered to be 35 minutes before sunrise,<ref>Rav Moshe Feinstein in Le-Torah ve-Hora'ah Vol. 3:7</ref> 60 minutes before sunrise,<ref>Rav Tukaczinsky in Eretz Yisrael 1:4</ref> and 66 minutes before sunrise.<ref>Rav Ovadya Yosef in Yechave Daat 2:8</ref> The various opinions would then have to be extrapolated according to the region of the world and time of year.<ref>There are two factors at work here: First, the processes of daybreak and nightfall occur faster at places near the equator than places further away from the equator. Second, the speed of these processes are also affected by the seasons. A common solution would be to use seasonal minutes. In order to calculate a seasonal hour, one would need to add up all the daytime minutes and then divide by 12 to get the number of minutes that are in each seasonal hour. For instance, if there were 11 hours of daylight, each seasonal hour would consist of 55 minutes(11x60:12=55min). To further complicate matters, there are two ways of counting the daytime minutes: The Magen Avraham counts from dawn until nightfall with the emergence of 3 stars, whereas the Gra counts from sunrise to sunset. Another means for calculation, which has only recently been implemented, is to compare the level of brightness by using the relative position of the sun. For instance, it has been determined that 60 minutes before sunrise on a perfect day in Jerusalem the sun is 12.9 degrees below the horizon. Therefore, if one wanted to find the equivalent time anywhere in the world during any season, one would simply need to determine at what time the sun will be 12.9 degrees below the horizon in that locale on that day and that would be the extrapolated Meshiyakir.</ref> Thus, according to the commonly accepted opinion that Meshiyakir is between 50 and 60 minutes before sunrise in Jerusalem - In New York, depending on the time of the year, it could be anywhere from 56-73 minutes before sunrise.<ref> MyZmanim.com. These figures are determined using MyZmanim’s earliest published position of 11.5 degrees below the horizon. Unfortunately, MyZmanim.com only offers calculations based upon 10.2 degrees, 11 degrees, and 11.5 degrees but not 12.9 degrees. It is unfortunate because 12.9 degrees correlates to Rav Tukaczinsky’s 60 minutes before sunrise which, although being a very lenient position, is also well collaborated and accepted.</ref>

# If one is pressed for an earlier time for work or travel reasons, there are opinions that one may make a bracha on Tzitzit already from dawn.<ref>Mordechai on Gemara Megilla 2; Rema 18:3</ref> Dawn is 72 equivalent minutes, or 1.2 seasonal hours, before sunrise.<ref>Rambam in Peirush HaMishnaiyot [[Brachot]] 1:1; Shulchan Aruch 459:2</ref>  However, most modern poskim<ref>Gra 18:5; Mishna Brurah 18:10</ref>  qualify that one should not rely on these minority opinions unless under “extreme circumstances”<ref>Rav Ovadya Yosef in Halacha Brura 2, 30:1.</ref> and should rather wait at least until the most lenient interpretation of [http://halachipedia.com/index.php?title=Reference_of_Measurements_in_Halacha#MeSheyakir Misheyakir].

# If one inadvertently made a bracha before dawn, one should not repeat another bracha when the correct time arrives.<ref>Mishna Brurah 18:10. He explains that we are cautious since perhaps the halacha follows the Rosh that daytime garments worn at night require Tzitzit and accordingly the bracha would have been correct; Kaf HaChaim 18:22; Halacha Brurah 1, 18:6</ref>  

# In terms of nighttime wear, one may wear Tzitzit at night without a bracha and can even sleep in them.<ref>Tosfot Gemara Niddah 51b; Rambam Hilchot Tzizit 3:8; Rema 21:3; Mishna Brurah ad loc; Yalkut Yosef Additions 1, 8:5. The exemption at night is based on the pasuk "uritem oto bamidbar" 15:39.  Rambam Hilchot Tzitzit 3:7 states that this applies to any garment being worn at nighttime. Rosh in Halachot Ketanot hilchot Tzitzit 1 says this refers to any nighttime garment regardless of when it is worn. Ran on Kiddushin 34a "eizo" says that any garment which is either usually worn at night or is currently being worn at night is exempt. </ref> One need not be worried about violating Baal Tosef when wishing to wear Tzitzit at night.<ref>Rambam Hilchot Tzizit 3:8; Kesef Mishna ad loc; Beit Yosef 8:13</ref>  In fact, according to kabbalistic sources, Tzitzit protect a person at night from destructive forces<ref>Shaar Kavanot Tefillat [[Arvit]]:1, Birkei Yosef 8:7, Kaf Hachayim 21:15, Ben Ish Chai Bereishit: halacha 9, Sh"t Teshuvos Vihanhagos 1:19, </ref> and therefore it is praiseworthy to do so. <ref> Kitzur S"A of Yalkut Yosef 8:5 </ref>
