Abaye answers: every 28 years This explanation provided by Abaye is based on a ruling of Shmuel also mentioned in the Talmud: [5] Shmuel stated: The vernal equinox occurs only at the beginning of one of the four quarters of the day, either at the beginning of the day or at the beginning of the night, or midday or midnight. The summer solstice only occurs at either at the end of 1. The autumnal equinox only occurs at the end of 3 or 9 hours of the day or the night. The winter solstice only occurs at the end of 4. The duration of a season of the year is no longer than 91 days and 7.

Needs cleanup[ edit ] At the moment, this article editorializes and goes off on quite a few tangents. Anyone wanna take responsibility for cleaning it up? I decided to just revert it and be done with it. I corrected the inaccuracies, but perhaps could not do anything about the other problems.

This Halachically we follow what is known as Tkufas Rav Adda that calculates a year as one nineteenth of d 16h chalakim, or This should somehow be clarified and expanded upon. KosherJava talk , 17 February UTC Granted, there still exists a few oversimplifications, both in regard to topics you mentioned, as well as the absence of any mention of Saturn. As to why March 25 was chosen as the halachic date, discussion on that will also be necessary. In trying to redraft this article, I have removed quite a number of untruths and included a lot more detail than was previously here, but it cannot be done in a day.

What is here now is certainly better than what was here, and it will only get better. Kol tuv. It is, rather, a consequence of the 19 year cycle being the best perpetual scheme to synchronize the tropical year with whole lunar months. There is actually no application of tekufas R.

Adda in any area which we can choose. Pahmer talk , 3 March UTC importance of covering this topic honestly. This article has made a large improvement over the last 2 weeks, but still has a way to go in being intellectually honest and effectively explaining the upcoming event of Birchat Hachammah.

Although Jewish people will be celebrating the exact position of the sun in relation to the earth at the same time and day of the week as during creation, I think it is undisputed among people who understand Birchat Hachammah, that this cycle is inaccurate.

And this celebrated event is not actually occurring at this set day and time. I read the artscroll book about Birchat Hachammah, which also did not address the true reality, and take the Julian calendar as a fact of nature. Wikipedia is not artscroll and the authors should try to explain this entire event and forthcoming and clearly as possible Something should be added to the effect of: The true position of the sun in relation to the earth at the same time of the week does not actually occur on this 28 year cycle.

The 28 year cycle is based on the Julian calendar The Julian calendar loses one day of accuracy about every years. This explains why Birchat Hachammah now occurs in the beginning of April, when it was meant to commemorate the suns position at creation at the vernal equinox which occurs on March 20 or Each proceeding 28 year cycle we are moving further away from the actual date of the vernal equinox.

Although the 28 year cycle is known not to be accurate, the accepted Jewish custom is to say the Birchat Hachammah blessing, which praised G-d for his works of creation. After that is superfluous to the issues, and before that is rife with hypercriticism.

Rabbi J. Is there any reason to keep it at Birchat? Again, the spelling of Hachama is not too important for me, but the k of Birkat is very important. YosefK talk , 8 May UTC Return to Creation[ edit ] Please contribute to the article in a positive manner only -- this means refraining from insisting that Birkat Hachama has anything to do with the Sun returning to its physical position as it was during Creation.

Such a return to a physical position occurs every year and coincides or rather, is the definition of the vernal equinox. The commemoration is of the co-incidence of the position with the timing.

At least be clear what it is you are arguing against. The myth and I agree with you in this characterization is NOT simply that the Sun returns to a particular position by which is meant the March equinoctial point on the ecliptic.

That does indeed occur every year. Rather, it is that the Sun returns there at the exact time of week at which, in Jewish belief, it was created, namely, Wednesday at zero hours. Zero hours means, here, as the hours of the day are counted in the Jewish calendar, in which the date changes at mean sunset, not 6 hours later when the civil date changes.

It IS a myth, not for the reasons you have given, but for the reasons I have given in the article: Myths and Maths of the Blessing of the Sun. DRosenbach Talk Contribs , 28 December UTC Ocurrences[ edit ] The eagle eyed among you will have noticed a change in the Occurrences section in the main article, to the following text, which originally read: "Birkat Hachama will always fall on March 25 in the Julian calendar" and now reads "March 26".

That was me. Let me explain: although in a Birkat Hachama year, the Shmuelian March equinox occurs on Tuesday, March 25 at , which is zero hours on Wednesday in the Jewish calendar , Birkat Hachama itself is observed about 12 hours later, by which time it is Wednesday in the Julian calendar as well, and therefore March 26th. For more information, read Myths and Maths of the Blessing of the Sun. The gematria of the tetragrammaton adds up to 26, not But even if it did add up to 28, so what?

What point were you trying to make? Is there a source for this? The distance between March 25 and April 8 is actually 14 days. The Hebrew calendar was established roughly years ago. This would account for a 12 day discrepancy. While September 25 is not the true equinox, it is the day in which there is "equal night".

My guess is that the halachic equinox was originally the day that is exactly 12 hours. This is a common concept in halacha, in which perception is reality.

If we use this explanation, the halachic vernal equinox is on April 8 because it is days and fifteen hours after the autumnal equinox which is the opinion of Shmuel. But, their main problem, still, is that they used a less-than-accurate year length of A more accurate year measure like The larger intervals give more accurate timing with less drift, but also means birkat happens less frequently.



Redemption in Birchat HaChama The blessing of the sun takes place in Nisan because this was the position of the sun at creation , but there is much more to the timing then meets the eye. The Talmud tells us that Nisan is the month of redemption. Eliezer says: In Tishri the world was created; in Tishri the Patriarchs were born; in Tishri the Patriarchs died; on Passover Isaac was born; on New Year Sarah, Rachel and Hannah were visited; on New Year Joseph went forth from prison; on New Year the bondage of our ancestors in Egypt ceased; in Nisan they were redeemed and in Nisan they will be redeemed in the time to come. Thus it is no accident that Birchat HaChama is performed in the month of our redemption. Birchat HaChama is a part of our redemption. Further, Nisan contains Pesach , the festival of our redemption , the festival that begins our journey back to Gan Eden , to the promised land!



Makora Following a controversial article on COLliveit seems like the Gaboim of are making a gesture towards compromise. Birkat HaChama falls on erev Pesach, Passover eve. Birchas Hachama in Uruguay To recalibrate the calendar, two adjustments were made:. Your general health and well-being will be better too. As explained below, the blessing is recited on the morning after the Sun completes its cycle; ideally, it should be recited at sunrise, [10] referred to in Jewish law as haneitz hachammah.
