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.

Good Friday, also called Holy Friday, Black Friday, or Great Friday, is a holiday observed primarily by adherents to Christianity commemorating the crucifixion of Jesus and his death at Calvary. The holiday is observed during Holy Week as part of the Paschal Triduum on the Friday preceding Easter Sunday, and often coincides with the Jewish observance of Passover. Based on the scriptural details of the Sanhedrin Trial of Jesus, the Crucifixion of Jesus was most probably on a Friday. The estimated year of Good Friday is AD 33, by two different groups, and originally as AD 34 by Isaac Newton via the differences between the Biblical and Julian calendars and the crescent of the moon. A third method, using a completely different astronomical approach based on a lunar Crucifixion darkness and eclipse model (consistent with Apostle Peter's reference to a "moon of blood" in Acts 2:20) arrives at the same date, namely Friday April 3, AD 33.

The Vixakha Bouxa festival is the Lao version of the Thai Visakha Puja, which it closely resembles. It commemorates the birth, enlightenment, and death of the Buddha, which are all said to have happened on the same date. It is held around the month of May or Vesak, based on the lunar calendar. Celebrations include dances, poems, parades, processions, deep meditation, theatrical performances, and puppet shows. One part of the Vixakha Bouxa festival is called Boun Bang Fay, or Rocket Festival. As this is during the hottest and driest season of the year, large homemade rockets are launched into the sky in an attempt to convince the celestial beings to send down rain. Traditionally, Buddhist monks made the rockets out of hollow bamboo tubes filled with gunpowder (among other things). Nowadays, lay people make the bang fai more like fireworks and hold competitions for the highest, fastest and most colorful rockets. The event takes on both sides of the Mekhong River border between Thailand and the Lao Peoples Democratic Republic, and sometimes teams from the neighbouring countries will compete against each other.

International Workers' Day (a name used interchangeably with may day) is a celebration of the social and economic achievements of the international labor movement.

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.

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).

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".

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
