#The text of this blessing as appears in the Talmud reads: Blessed are you God.. Who with his utterance created the heavens.. Who renews the months, etc.<ref>Sanhedrin, ibid. Shulchan Aruch 426:1 </ref> In this blessing we express our recognition of God awesome power over the universe. As such, one should be vigilant to recite this blessing with full intent, devotion and elation. <ref>Ben Ish Chai (Vayikra 26) and More Be'ezbah 187</ref> | #The text of this blessing as appears in the Talmud reads: Blessed are you God..

#Since this blessing is involves the greeting of the Divine Presence, it is most proper that it's recital be in | #Since this blessing is involves the greeting of the Divine Presence, it is most proper, when possible, that it's recital be in standing. <ref>Gemara Sanhedrin 42a, Shulchan Aruch 426. The Gemara relates that Mereimar and Mar Zutra in their later years would be supported by their attendants in order to recite this blessing while standing, see Rashi there. </ref> When not feasible (eg. elderly or sick persons) it may be recited in sitting. | ||
#It is also preferable, when possible, that this blessing not be recited indoors, but rather outdoors under the open skies, as is the way to go out toward to greet one of prominent stature. <ref>Shiltei Ha'giborim (Berachos 189:3), Bach 426 and Responsa Teshuvos Ha'bach (no. 80)</ref> Preferably one should also not be positioned beneath a roof or overhang.<ref>Rama 426:4 with Mishnah Brurah (21). Orchos Rabbenu (v. 1 p. 178) however, brings from the Chazon Ish that this optimal condition is only to refrain from it's recital in indoor structures, but once outside one may recite the blessing under an overhang. See Responsa Yaskil Avdi for a discussion on it's recital under a tree's branch, and Mishnah Berura Dirshu (42) regarding it's recital under an umbrella. </ref> When not feasible, this recommended condition may be waived, provided the moon's illumination is still visible to the reciter indoors (eg. through a window or door). | |||

#One may say Birkat HaLevana until 15 days after the molad, however, on the 16th day one should say it without [[Shem UMalchut]]. Some say that one may only say it until 14¾ days after the molad. <ref>Shulchan Aruch 426:3 rules like the opinion of Nehardai in Gemara Sanhedrin 41b who say that one has 15 complete days. Chazon Ovadia Chanuka p. 349 agrees unlike the opinion of the Rav Poalim. However, the Rama 426:3 writes that one may only say it up to half of 29 days, 12 hours, and 793 chalakim. Beiur Halacha s.v. VeLo writes that if one is in such a situation where half of 29 days, 12 hours, 793 chalakim passed and 15 days have not, there is what to rely on to say the Bracha. Beiur Halacha adds that if it’s the 16th day one should say it without [[Shem UMalchut]]. Sh”t Yabia Omer 6:38 agrees with the Beiur Halacha that on the 16th day one should say it without [[Shem UMalchut]]. </ref> A chart of the time of the upcoming molads is printed here (see note for calculation)<ref>Rambam ([[Kiddush]] HaChodesh 6:3) writes that from one Molad (the astronomical time when the new moon can be seen) to another is 29 days, 12 hours, and 793 chelakim (and there's 1080 chelakim in an hour). The Rambam 6:8 also writes that the time with which to begin to calculate the Molads from the beginning of creation is the 2nd day, 5 hours, and 204 chelakim. To calculate the Molad of [[Rosh Chodesh]] Tishrei 5773, first let us calculate the number of months which passed from creation and then add the appropriate time for each month. Although there are 12 months in a regular year because there are 7 leap years in a 19 year cycle, there is an average of 12.3684 lunar months a year. By Tishrei 5773, 5772 complete years have passed, meaning that 71390 complete months have passed since creation. The chelakim for the molad of Tishrei 5773 should be 1034 (i.e. 204 + (71390 * 793) modulo 1080) which is equal to 57 minutes and 8 chelakim. Making similar calculations leads to conclude that the Molad for Tishrei 5773 is 1am (i.e. 5+12*71390+(204+71930*793-1034)/1080) mod 24 starting from 6pm) Sunday (i.e. 2+1*71390+(909103-37879)/24 mod 7). The other months can then be calculated from that starting point by either adding or subtracting the interval for each month (1 day, 12 hours, 793 chelakim. To confirm these calculations, one can check the [http://www.chabad.org/library/article_cdo/aid/216238/jewish/Molad-Times.htm Chabad.org page of Molad times].</ref>: | #One may say Birkat HaLevana until 15 days after the molad, however, on the 16th day one should say it without [[Shem UMalchut]].

#The strict halacha allows saying birkat halevana on Shabbat and Yom Tov, but since the kabbalists recommend against it one shouldn't do it unless one is running out of time to say it.<ref>The Rashba (responsa 4:48) quotes someone who said that it is forbidden to say birkat halevana on Friday night since it is like travelling out of the techum above ten tefachim. The Rashba doesn't understand that opinion. He argues that there is no techum above ten tefachim and also it is greeting Hashem and not the moon; therefore, it isn't at all like travelling out of the techum and is permissible to be recited on Shabbat. The Mishna Brurah 426:12 rules that it is permissible to say kiddush levana on Shabbat and Yom Tov if it is necessary. In the Shaar Hatziyun 426:12 he adds a reason that everyone can agree with; since it is a mitzvah filled with happiness a person might come to dance and it is forbidden to dance on Shabbat.</ref> | #The strict halacha allows saying birkat halevana on Shabbat and Yom Tov, but since the kabbalists recommend against it one shouldn't do it unless one is running out of time to say it.<ref>The Rashba (responsa 4:48) quotes someone who said that it is forbidden to say birkat halevana on Friday night since it is like travelling out of the techum above ten tefachim.
