The rabbis decide it must be the spring month of Nissan, as  the first month,  as that is when all of the other nations'  sages consider the year to begin. This was the opinion of Rabbi Joshua.  (Talmud Bavli Tractate Rosh Ha Shana 11b). But he did not base his opinion  on when other nation's sages agreed that the New Year began in Spring,  alone.  Rabbi Joshua based his opinion on when the constellation, Pleiades  (Kimah in Hebrew), sets at day break and fountains dry up. But God reversed  this to punish humankind and made Kimah rise at day break and made the fountains  overflow.
  
 Kimah is said to also be responsible for giving fruits their  individual tastes and smells based on Job 38:31. One makes a beracoth not  only for the fruit, but one to thank Ha Shem for the smell of  a ripe  fruit. This 7 star cluster is known as the Seven Sisters and is in the  constellation Taurus. In Hebrew Kimah is derived from the word for  cluster.[kum=heap or accumulate]. Job 38:31-34 has God asking Job:  " Can  you  bind the sweet influences of Pleiades, or loose the bands of  Orion?   ....Can you shout an order to the clouds and cover  yourself with a flood of water? ''   Talmud Yerushalmi Tractate  Ta'anit 64a goes even further than Rabbi Joshua  in the Bavli,  and says that Kimah is the ''cause of the flood.'' And what Zodiac sign  is  for the month of Iyar? Taurus. 
  
 The Talmud Bavli Tractate Zevachim 113b gives more  supporting evidence that Iyar is the month of the start and end of the Ark's  journey. The rabbis speak of a large bullock, a giant Taurus if you will, who  was in  modern measurements, 3 miles long, who could not fit into the Ark.  Its name is Re'em. Noah strapped  it to the side of Ark, and Noah feed it.  Some translate Re'em as a unicorn, but  using that view, based on its size,  it may have been a giant rhinoceros. King David had a run in with a Re'em in  the Midrash.
  
 So now from just the story of Noah, we can see the importance,  of constellations, the sun and the moon. 
  
 The Mechilta  (Midrash on Exodus) of Rabbi Shimon bar  Yochai and the Midrash Ha Gadol on Exodus 12:2 say, "'This month is for you' -  The forefathers did not count from it." This is similar to what the Mechilta   of Rabbi Yishmael says on that verse, "'This month is for you' - Adam did  not count from it." In other words, the entire concept of calculating months  based on the moon and starting from Nissan did not apply before the Jews left  Egypt. Folks used the solar year.  Similarly, Rabbi Avraham bar Chiya  Ha Nasi (early 12th century) writes in his Sefer HaIbbur 2:5, the most important  book written on the Jewish calendar, "Observing this commandment, that is the  lunar month and the intercalation of the year, we were obligated only from the  Exodus." Rabbi Yitzhak Ha Yisraeli (14th century) writes similarly in his Yesod  Olam 4:2.
  
 The concept of an unpredictable  moon that had  rabbis praying to God or throw  rocks at it, shows the Rabbis in Judea to  be astronomically dense.   The Greeks could calculate lunar cycles  circa 200 years before our above mentioned rabbis were tossing stones at  celestial orbs.   
  
 When we study the   Jewish calendar   development, we find that for every new piece of data added, which was seemly  new to the rabbis, this information was know to the rest of the world for  centuries.
In typical of the legal fiction used in  the Talmud to effect changes, our sages tell us they know more about the  skies then other nations.    "R. Shmuel son of Nachmani said in  the name of R. Yochanan: How do we know that it is a mitzvah to calculate times  and constellations? Because it is said (Deut. 4): 'and you shall keep and do it,  because this is your wisdom and cleverness in the eyes
of the nations.'  
  
 The rabbis ask what kind of cleverness and wisdom is in the  eyes of the nations and conclude it must be calculating times and  constellations" (Talmud Bavli Tractate Shabbat 75a). The French Rabbinic  medieval commentary on Talmud Bavli Tractate Ketuboth 111a) reads that the  calculation of the leap month of two Adars were to be kept secret from  non-Jews. This may have been a jab at the Islamic lunar calendar, with no leap  month, causing Ramadan to fall in any season of the years, while Passover always  is a spring Holiday. If the Arabs wanted to have a calendar like ours, they  could have as they had more knowledge in astronomy that our rabbis. Hebrew  holidays were all seasonal and agricultural based. Islam does not have holidays  that have roots in agricultural.
  
  
 Now Yerushalmi portrays the Solar year as orderly. They cannot  depend on the moon as one must literally site it and one just cannot if its a  cloudy night. So only by asking God to lift the clouds or throwing rocks at the  moon, could the rabbis on cloudy nights, determine their calendar.
  
 Now, we have a lot of cultural things happening with the lunar  calendar in the land of the Talmud Yerushalmi that we did not have in  the  land of the Talmud Bavli.
  
 A major problem were the Samaritans who moved into The Land  during the Babylonian exile, who were not accepted as Hebrews when Ezra   et. al. returned. The Samaritans would send signals of new moon sightings on the  wrong day to confuse Hebrews and the Jews who developed from  Hebraism.
   
 The Land borders Egypt whose tradition was solar. Their main  god was Ra, the Sun God. At one point, pre Hebraism, they were monotheistic,  worshipping only Ra.
  
 And the Romans, who controlled Judea, used a solar calendar.  They wanted to do away with Judaism, as it competed with their money making  taxable Hebraic Temple. They outlawed all TaNaK study and disallowed semikah,  rabbinic ordination. A group of rabbis standing outside at night in Judea trying  to figure out if there was a new moon, would have been suicidal and well,  lunacy.
  
 And the Roman's controlled Sanhedrin in Judea was continually  having  a power play with the Babylonian academies. A solar calendar which  they could control would place them in a competitive  advantage over the  Babylonian rabbis. 
  
 In the lands of Persia, which was Babylon, and now Iraq,  Iran, and many of the Stans of the old USSR, the lunar calendar was used.  Astrology and constellations played  a major role. Many of Judaism's months  were  named from Babylonian months. And unlike the constellations which  start and end in the middle of solar months, lunar month's contained a whole  constellation. Nissan , when we sacrificed a Pascal lamb, has Aires, the  Ram, as its sign. Tishrei when God judges us, has a scale, Libra, as its  constellation. 
  
 So Babylonia Jews would be more influenced by the lunar  months, than solar.
  
 Using the Noah story some more, we need to examine what  exactly was this Hamas that humans did to cause themselves to be destroyed by  the 2nd Parasha of the whole TaNaK? Among other things they were out of  synchrony with nature. Besides mating animals of totally different species,  and trees and grains as well, they tried to live without paying attention to the  nature rhythms of the sun and moon. They planted during the wrong times and  ignored the general idea that one goes to sleep when its dark and awakes when it  is light. The sun and moon were meaningless to them.
  
 In fact, similar to our life style today, when we can get  fruits, not in their season, but 12 months a year flown in from around the  globe, or when we can stay up all night with artificial lighting,  the Tractate Perkei d' Rabbi Eliezar Chapter 23, states that during the  Noah year's voyage there was no sunlight. The only way Noah and his family knew  when to feed the animals is because Noah brought special precious gems on board  that sparkled in the day, and were dull at night.   
  God's seal is the Rain Bow. Why? Because when the first  time it started to rain again, Noah and his sons, as well as Mrs.  Naamah Noah and the sons' wives would be scared to death.  Should they  get umbrellas or run back to the Ark?  The Rain Bow, which comes with rain,  tells them an umbrella is sufficient this time. When sunlight hits rain drops at  a specific angle, the light enters the drop, is reflected inside, and then exits  the drop. Entering and exiting the drop, the colors are separated. We see  red light exiting from a raindrop because that drop is at just the  correct  42 degree angle between our eye and the sun so that the red light  coming from the sun is refracted, reflected, and refracted again right into our  eye. Blue light comes from another raindrop at a slightly different angle. All  the raindrops that are at a certain angle between our eye the sun form a circle  in the sky. That is why the rainbow is a bow of a circle.   
 And this circle is beautiful to the eye. It reminds us that  God and the Earth do quite well without humans interference. The Bow is a  product of water and sun, to remind us that the Sun dried the waters of the  deluge. And that in this combination of light refracted through water are all of  the colors of the Universe, all the animals of the earth, all the different  peoples on this planet, all the different colors of vegetables and fruits, all  the different shades of various landscapes, from tan deserts, white glaciers,  to emerald rain forests.  Indeed the Rain Bow is  symbolic of the Breath of Life of YahWeh Himself. The bow that  Noah's half brother invented, [Gen. 5:29] and [Gen. 4:22] and which his father  accidentally killed Cain with, now goes from being an instrument  of death  to a promise of life.
  
 So it is obvious to us at least, that both Calendars have  their importance. Neither one is more appealing or appalling than the other when  we peal back Parasha Noah. They both have their defects and both have their  strengths. Like humans, they are both flawed when humankind tried to measure the  Divine. The lunar calendar needs a leap month here and there, and the Solar  needs an extra day tossed on to February every 4 years.
  
 Why do we celebrate Rosh Chodesh and not the sun? Chodesh  literally means renewal. The sun  always appears whole except during a  Solar Eclipse. Each year because a solar year is measured with one quarter day  at the end, a solar year, which we moderns celebrate on January One, but used to  celebrate it on April One, which ties into Nissan being the first month of the  year, would be celebrated 6 hours apart for every 4 years. One the first year  after a leap year, the new year really would be 6 AM on January One and not  midnight. On the second year it would be noon. One the third year it would be 6  PM and only on the 4th year, leap year, would it be midnight, as we added a  whole day. We just choose  to toast at Midnight each December 31-January  One, but its incorrect.
  
 The Moon goes thru cycles. It waxes and wanes. One cannot look  at the Sun and know what part of the month we are in. The sun looks the same.  But one can look at the moon, two days in a row, and know if it is waxing or  waning, and hence know if one is in the first two or second two weeks of the  lunar month. By observing the size of the moon, one can then with accuracy,  determine what week in the lunar month one is in.
  
 During the day, with the sun, one can tell what season one is  in.
  
 The Jewish people wax and wan. We as humans wax and wan. We  can be '''riding high in April and shot down in May.'' By using the moon as a  symbol it reminds us to have faith in Ha Shem,, that Gamzu l'Tovah, all is for  the good, and that the ''darkest hour is just before dawn.'' When our lives seem  to be waning, we know, like the moon, we will wax again. We are promised   Jewish Spiritual Renewal if only we ask God for it.
  
 In 2008, the Winter Solstice was on 12/21/08. In  2009  the Spring equinox was 3/20/09, the Summer Solstice was 6/21/09, and the Autumn  Equinox will be  9/22/09. 12/21/09 was Erev Chanukah, was 10 days  after Purim, and 26 before Pesach. June 21,2009 was a day before Rosh Chodesh  Tammuz. And on 9/22/09 it will be day after the fast of Gadaliah. It  is not celebrated, and the winter  Solstice tends to fall into the rabbinic  holiday of Chanukah, but they are not ignored. 
  
  The four solstices  and equinox; Te'ufot, of Nissan, Tammuz, Tishrei, and Tevet are often mentioned  as determining the seasons of the year, and there are occasional references to  the rising place of the Sun (Talmud Bavli Tractate Eruvim 56a). Sometimes six  seasons of the year are mentioned (Midrash Genesis Rabbah 34:11) and reference  is often made to the receptacle of the Sun by means of which the heat of the orb  is mitigated (Midrash Genesis Rabbah 6:6, and elsewhere). The Moon was also a  part of the calendar: "The moon begins to shine on the 1st of the  month; its light increases until the 15th, when the disk is full;  from the 15th to the 30th it wanes; and on the  30th it is invisible." (Midrash Exodus Rabbah 15:  26).
   
 Traditionally, Jews welcome the first of the month with a  special prayer for the new moon. Rosh Hashanah always falls, as per the law in  Numbers, on the new moon of Tishrei . Yet no new moon prayer is said. The rabbis  say that this is "in order to confuse Satan." The sages say that Satan is  waiting for Rosh Hashanah in order to speak ill of us before God. The rabbis  decree that if we do not say the new month prayers, Satan may not know it is  Rosh Hashanah and could miss his chance.
  
 What is the lesson of all of this? Don't waste time. As God  promised Noah and us, ''continuously, all the days of the earth, seedtime and  harvest, cold and heat, summer and winter, day and night, shall not cease.''  As I teach: "Make Love, Not Makloket.''
