Rosh Hashanah (Hebrew: ראש השנה‎), (literally "head of the year"), is the Jewish New Year. It is the first of the High Holy Days or Yamim Nora'im ("Days of Awe") which occur in the autumn. Rosh Hashanah is celebrated on the first two days of Tishrei. It is described in the Torah as יום תרועה (Yom Teru'ah, a day of sounding [the Shofar]).^[1] Rosh Hashanah customs include sounding the shofar and eating symbolic foods such as apples dipped in honey.

The term "Rosh Hashanah" does not appear in the Torah. Leviticus 23:24 refers to the festival of the first day of the seventh month as "Zikhron Teru'ah" ("a memorial with the blowing of horns"), it is also referred to in the same part of Leviticus as 'שַׁבַּת שַׁבָּתוֹן' or penultimate Sabbath or meditative rest day, and a "holy day to God". These same words are commonly used in the Psalms to refer to the anointed days. Numbers 29:1 calls the festival Yom Teru'ah, ("Day [of] blowing [the horn]") and symbolizes a number of subjects, such as the Binding of Isaac and the animal sacrifices that were to be performed.^[2][3] (In Ezekiel 40:1 there is a general reference to the time of Yom Kippur as the "beginning of the year",^[2]

Navratri, Navaratri, or Navarathri (Hindi: नवरात्रि; Gujarati: નવરાત્રી; Tamil: நவராத்திரி; Sanskrit: नवरात्रम्; Marathi: नवरात्र; Punjabi: ਨਰਾਤੇ Nepali: नवरात्रि; Bengali: নবরাত্রি; Kannada: ನವರಾತ್ರಿ; Telugu: దుర్గా నవరాత్రులు; Malayalam: നവരാത്രി; Tulu: ನವರಾತ್ರಿ/നവരാത്രി) is a Hindu festival of worship of Shakti and dance & festivities. The word Navaratri literally means nine nights in Sanskrit, nava meaning nine and ratri meaning nights^[2]. During these nine nights and ten days, nine forms of Shakti/Devi are worshiped. The 10th day is commonly referred to as Vijayadashami or Dussehra.

The beginning of spring and the beginning of autumn are two very important junctions of climatic and solar influence. These two periods are taken as sacred opportunities for the worship of the Divine Mother. The dates of the festival are determined according to the lunar calendar.
