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]

Several nations of the world hold an annual Armed Forces Day in honor of their military forces.

Բանակի օր (Army Day) is celebrated on 28 January to commemorate the formation of the armed forces of the newly independent Republic of Armenia in 1992.^[1]

International Talk Like a Pirate Day (ITLAPD) is a parodic holiday created in 1995 by John Baur (Ol' Chumbucket) and Mark Summers (Cap'n Slappy), of Albany, Oregon,^[1]U.S., who proclaimed September 19 each year as the day when everyone in the world should talk like a pirate.^[1] For example, an observer of this holiday would greet friends not with "Hello," but with "Ahoy, matey!" The holiday, and its observance, springs from a romanticized view of the Golden Age of Piracy. It has become a holiday for members of the Church of the Flying Spaghetti Monster.^[2]

According to Summers, the day is the only holiday to come into being as a result of a sports injury. He has stated that during a racquetball game between Summers and Baur, one of them reacted to the pain with an outburst of "Aaarrr!", and the idea was born. That game took place on June 6, 1995, but out of respect for the observance of D-Day, they chose Summers' ex-wife's birthday, as it would be easy for him to remember.^[1][3]

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.
