In countries which use the Gregorian calendar, New Year's Day is usually celebrated on 1 January. The order of months in the Roman calendar has been January to December since King Numa Pompilius in about 700 BC, according to Plutarch and Macrobius. However, Roman writers identified years by naming the year's consuls, who did not enter office on 1 January until 153 BC. Since then 1 January has been the first day of the year, except during the Middle Ages when several other days were the first (1 March, 25 March, Easter, 1 September, 25 December). With the expansion of Western culture to the rest of the world during the twentieth century, the 1 January date became global, even in countries with their own New Year celebrations on other days (e.g., China and India). At present, the celebration of the New Year is a major event worldwide. Many large-scale events are held in major cities around the world, with many large fireworks events on New Year's Eve (31 December). Sydney launched over 80,000 fireworks at midnight, and had more than one and a half million attendees; it was also the most-watched event on television worldwide last year. In Valparaiso upwards of two million visitors witnessed the largest fireworks display in a natural setting; a total of more than 21 kilometers of fireworks on the bay, from the commercial port city of Valparaiso to Concon, Chile, all in 25 minutes of entertainment. London's New Year celebrations centre around the London Eye, with an impressive fireworks display while Big Ben strikes midnight. In New York, the celebration is focused around a large crystal ball that descends in a one minute countdown in Times Square. Edinburgh plays host to one of the world's largest Hogmanay events. The celebrations last for four days and attract visitors from around the globe to take part in street parties and attend concerts. In the culture of Latin America there are a variety of traditions and superstitions surrounding these dates as omens for the coming year. January remains a symbol of the New Year's celebration. According to the Christian tradition, 1 January coincides with the circumcision of Christ (eight days after birth), when the name of Jesus was given to him (Luke 2: 21).

Eid ul-Fitr (Arabic: عيد الفطر ‘Īdu l-Fiṭr‎), often abbreviated to Eid, is a Muslim holiday that marks the end of Ramadan, the Islamic holy month of fasting. Eid is an Arabic word meaning "festivity", while Fiṭr means "to break fast"; and so the holiday symbolizes the breaking of the fasting period. It is celebrated after the end of the Islamic month of Ramadan, on the first day of Shawwal. Eid ul-Fitr lasts for three days of celebration and is sometimes also known as the "Smaller Eid" (Arabic: العيد الصغير al-‘īdu ṣ-ṣaghīr‎) as compared to the Eid ul-Adha that lasts four days and is called the "Greater Eid" (Arabic: العيد الكبير al-‘īdu l-kabīr‎). Muslims are commanded by the Quran to complete their fast on the last day of Ramadan and then recite the Takbir all throughout the period of Eid.

Diwali or Dīpāvali (Sanskrit: दीपावली,Nepali: दिपावली, Hindi: दिवाली, Marathi: दिवाळी, Kannada: ದೀಪಾವಳಿ, Konkani: धाकली दिवाळी, Tamil: தீபாவளி, Telugu: దీపావళి, Urdu: دیوالی, Oriya: ଦୀପାବଳୀ) is a significant 5-day festival in Hinduism, Sikhism, and Jainism occurring between mid October and mid November. It is also popularly known as the Festival of Lights. The word दीपावली (Dipavali) literally translates as a row of lamps in Sanskrit. It is traditional for adherents of Diwali-celebrating faiths to light small clay lamps (or Deep in Sanskrit: दीप) filled with oil to signify the triumph of good over evil within an individual. During Diwali, many wear new clothes and share sweets/snacks with each other. Some Indian business communities start their financial year by opening new account books on the first day of Diwali for good luck the following year. In Hinduism, Diwali marks the return of Lord Raama to his kingdom Ayodhya after defeating Ravana (the demon king) - the ruler of Lanka in the epic story of Ramayana. It also celebrates the slaying of the demon king Narakasura by Lord Krishna. Both signify the victory of good over evil. In Jainism, Diwali marks the attainment of moksa by Mahavira in 527 BC. In Sikhism, Diwali commemorates the return of Guru Har Gobind Ji to Amritsar after freeing 52 other Hindu kings imprisoned in Fort Gwalior by Emperor Jahangir. He was welcomed by the people who lit candles and divas to celebrate his return, which is why Sikhs also refer to Diwali also as Bandi Chhorh Divas meaning "the day of release of detainees".

Ganesha Chaturthi (गणेश चतुर्थी), also known as Vinayaga Chaturthi (Tamil: விநாயக சதுர்த்தி) is the Hindu festival of Ganesha, the son of Shiva and Parvati, who is believed to bestow his presence on earth for all his devotees in the duration of this festival. It is the birthday of Ganesha who is widely worshipped as the god of wisdom, prosperity and good fortune. The festival is observed in the Hindu calendar month of Bhaadrapada, starting on the shukla chaturthi (fourth day of the waxing moon period). The date usually falls between 20 August and 22 September. The festival lasts for 10 days, ending on Anant Chaturdashi (fourteenth day of the waxing moon period).

Thaipusam (Tamil: தைப்பூசம்) is a Hindu festival celebrated mostly by the Tamil community on the full moon in the Tamil month of Thai (January/February). It is celebrated not only in countries where the Tamil community constitutes a majority, but also in countries where the Tamil community is a minority, such as Singapore and Malaysia. The festival is also referred to as Thaipooyam or Thaippooyam തൈപ്പൂയം in the Malayalam language. The word Thaipusam is derived from the month name Thai and Pusam, which refers to a star that is at its highest point during the festival. The festival commemorates the occasion when Parvati gave Murugan a vel (spear) so he could vanquish the evil demon Soorapadman. There is a misconception among people that Thaipusam marks Murugan's birthday; however, it is believed that Vaikhasi Vishakam, which falls in the Vaikhasi month (May/June), is Murugan's birthday.

Maha Shivaratree (February) is literally "The Great Night of Siva." Hindu devotees set on foot pilgrimage from all over the island for the sacred lake at Grand Bassin, usually carrying a `Kanwar' - light wooden arches covered in flowers. At Grand Bassin, pilgrims collect holy water which is ritually poured over a statuette of Siva in re-enactment of the classical myth according to which Siva's throat had to be cooled down after he drank the poison from the oceans to spare mankind. The seas became poisoned during the churning of the ocean which, according to one creation myth, gave rise to the universe.

Chinese New Year or Spring Festival is the most important of the traditional Chinese holidays. It is sometimes called the "Lunar New Year" by English speakers. The festival traditionally begins on the first day of the first month (Chinese: 正月; pinyin: zhēng yuè) in the Chinese calendar and ends on the 15th; this day is called Lantern Festival. Chinese New Year's Eve is known as Chúxī. It literally means "Year-pass Eve". Chinese New Year is the longest and most important festivity in the Lunar Calendar. The origin of Chinese New Year is itself centuries old and gains significance because of several myths and traditions. Ancient Chinese New Year is a reflection on how the people behaved and what they believed in the most. Celebrated in areas with large populations of ethnic Chinese, Chinese New Year is considered a major holiday for the Chinese and has had influence on the new year celebrations of its geographic neighbors, as well as cultures with whom the Chinese have had extensive interaction. These include Koreans (Seollal), Tibetans and Bhutanese (Losar), Mongolians (Tsagaan Sar), Vietnamese (Tết), and formerly the Japanese before 1873 (Oshogatsu). Outside of Mainland China, Hong Kong, Macau, and Taiwan, Chinese New Year is also celebrated in countries with significant Han Chinese populations, such as Singapore, Indonesia, Laos, Malaysia, the Philippines, and Thailand. In countries such as Australia, Canada and the United States, although Chinese New Year is not an official holiday, many ethnic Chinese hold large celebrations and Australia Post, Canada Post, and the US Postal Service issues New Year's themed stamps.

All Saints' Day (in the Catholic Church officially the Solemnity of All Saints and also called All Hallows or Hallowmas), often shortened to All Saints, is a solemnity celebrated on 1 November in Western Christianity, and on the first Sunday after Pentecost in Eastern Christianity, in honour of all the saints, known and unknown. In terms of Western Christian theology, the day commemorates all those who have attained the beatific vision in Heaven. In the Roman Catholic Church, the next day, All Souls' Day, specifically commemorates the departed faithful who have not yet been purified and reached heaven. It is a national holiday in many historically Catholic countries.

During the 19th century, Bihar was one of the four sub-provinces of the Bengal Presidency of British India. Bihar was the most important regional source of indentured labourers who worked and lived on the sugar estates of Mauritius. Between 1834 and 1890, the indentured workers from Bihar consisted around 40% of all the contractual labourers who were brought to the island. During that period, it is estimated that more than 170,000 indentured labourers out of the more than 430,000 workers who were landed in Port Louis were from districts located in Bihar. In addition, between 1849 and 1890, more than 130,000 of these Bihari workers passed through the Aapravasi Ghat site. In Calcutta, the majority among them transitted through the Mauritius Emigration Depot at Bhawanipur and the majority of these workers were adult males between the age of 18 and 50. he Bihari indentured labourers who came to Mauritius were mostly Hindus with some Muslims and Christians. They came from districts located within Bihar such as Gaya, Ghazipur, Arrah, Gorakpur, Sahabad, Azmbargh, Patna, Ranchi, Murzaffurpur. There is also archival evidence to show that as early as the mid-1830s and early 1840s, there were thousands of tribals who were brought as contractual workers. Between 1834 and 1870, more than 60,000 tribals coming mostly from Bihar were landed in Port Louis. On 2nd November 1834, 36 hill coolies from Bihar arrived in Port Louis harbour on board the ship the Atlas. They were landed near the present-day surviving stone structures of the Customs House by Mr. Arbuthnot, a British planter settled in Mauritius with the approval of Governor Nicolay. The arrival of these indentured labourers is commemorated as a national public holiday each 2nd November in Mauritius.

Christmas or Christmas Day is an annual Christian holiday commemorating the birth of Jesus Christ. It is celebrated on December 25, but this date is not known to be Jesus' actual birthday, and may have initially been chosen to correspond with either the day exactly nine months after some early Christians believed Jesus had been conceived, a historical Roman festival, or the date of the northern hemisphere's winter solstice. Christmas is central to the Christmas and holiday season, and in Christianity marks the beginning of the larger season of Christmastide, which lasts twelve days
