When studying religions there are different types of rituals and events. As in Judaism, they set aside certain holidays and days of remembrance. These holy days are scheduled with a different type of calendar. The Jewish use a lunar calendar this calendar is based on three astronomical phenomena: the rotation of the earth’s axis (a day), the revolution of the moon about the earth (a month), and the revolution of the Earth about the sun (a year). (Cation) The Jewish calendar beings when the first sliver moon becomes visible. As with the secular calendar almost every holiday falls on the same date, but with the Jewish calendar these dates would not be on the same date but in the same season. It is important to understand the lunar calendar in this religion because all the holy days are base on this type of calendar. As with the secular calendar almost every holiday falls on the same date, but with the Jewish calendar these dates would not be on the same date but in the same season. All Jewish holidays begin the night before the date of the holiday. The reason the Jews start the holiday the night before is from the story in Genesis ch1, it says "And there was evening, and there was morning, one day." From this they believe that the day begins at sunset and with that being said ends at the nightfall of the next day. They also have strict rules about work on specific holy days, which is work is not permitted. There is thirteen holy day in which work is not permitted Rosh Hashanah, Yom Kippur, the first and second day of Sukkot, Shermini Atzeret, Simchat Torah, Shavu’ot, and on the first, second, seventh and eighth days of the Passover. This can be a problem for Jews who follow these strict rules and live on the secular calendar as sometimes these holidays are during the workweek. The holy day of Yom Kippur is the most sacred day of the year. This holiday is the day of atonement, the day to make up from the faults they have made throughout the year. On this day they pray and fast most do not attend work and go to synagogues. This entire period is considered the Day of Awe, because of the mood of solemn judgments. But not long after the Days of Awe, comes the Joyful holiday of Sukkot. This holiday begins fifth day after Yom Kippur. It is quite the opposite of Yom Kippur in that Sukkot is one of the most joyous holidays. It is consider the Season of our Rejoicing. Sukkot is considered a shelter or a booth. In early days some families slept outdoors in the fields during harvest season, so they could start work in the fields early and stay late. They were also able to protect what they had harvested that way. Sukkot is celebrated in the remembrance of the period of wandering the desert this holiday last for seven days. To honor the holiday many Jewish families build and dwell in the temporary shelter, just as in earlier days. A sukkah must have at least two walls cover with material that will not blow with the wind. The sukkah can be any size as long as it is large enough to dwell inside of it. Another observant during Sukkot is called the four species, they are commanded to take four plants and use them to rejoice before the Lord. The four plants are etrog (a citrus fruit like a lemon and is native to Israel), Lulav (a palm branch), aravot (two willow branches), and hadassim (three myrtle branches). These six branches are put together and are called lulav. They are called this because the palm tree is the biggest branch. With these plants in hand one person will say a blessing while waving them in all direction. This is to symbolize that God is everywhere. On this holiday Jews finish the yearly cycle of reading portions of the form the Torah. They read the concluding lines of Deuteronomy (last book of the Torah) and follow that by reading the opening lines of Genesis (first book of the Torah) this is to show that Jewish study is everlasting; it has no beginning and no end. To show their joy, In Israel they dance in the streets with their Torah and scrolls, this is the most beautiful day of Sukkot.
