Holi - in India, Nepal, Sri Lanka
The main day, Holi, also known as Dhuli Vandana in Sanskrit,also Dhulheti, Dhulandi or Dhulendi, is celebrated by people throwing coloured powder and coloured water at each other. Bonfires are lit the day before, also known as Holika Dahan (burning of Holika) or Chhoti Holi (little Holi). The bonfires are lit in memory of the miraculous escape that young Prahlad accomplished when Demoness Holika, sister of Hiranyakashipu, carried him into the fire. Holika was burnt but Prahlad, a staunch devotee of god Vishnu, escaped without any injuries due to his unshakable devotion. Holika Dahan is referred to as Kama Dahanam in South India.
Holi is celebrated at the end of the winter season on the last full moon day of the lunar month Phalguna (February/March), (Phalgun Purnima), which usually falls in the later part of February or March. In 2009, Holi (Dhulandi) was on March 11 and Holika Dahan was on March 10. In 2010, Holi was on March 1 and Holika Dahan was on February 28.
Krishna Janmashtami - India
Krishna Janmashtami is observed on the Ashtami tithi, the eighth day of the dark half or Krishna Paksha of the month of Shraavana in the Hindu calendar, when the Rohini Nakshatra is ascendant. The festival always falls within mid-August to mid-September in the Gregorian calendar. In 2009, for example, the festival was celebrated on the 14th of August.
Rasa lila or dramatic enactments of the life of Krishna are a special feature in regions of Mathura and Vrindavan, and regions following Vaishnavism in Manipur. While the Rasa Lila recreates the flirtatious aspects of Krishna's youthful days, Govinda Pathaks or Dahi Handi celebrate the God's playful and mischievous side, where teams of young men form human pyramids to reach a high-hanging pot of butter and break it.
Eid al-Adha - Saudi Arabia
"Festival of Sacrifice" or "Greater Eid" is an important religious holiday celebrated by Muslims worldwide to commemorate the willingness of Abraham (Ibrahim) to sacrifice his son as an act of obedience to God, but instead was able to sacrifice a ram (by God's command). Eid is also about spending time with family and friends, sacrifice, and thanksgiving for being able to afford food and housing. In traditional or agrarian settings, each family would sacrifice a domestic animal, such as a sheep, goat, cow, or camel, by slaughter (though some contemporary Muslims do not sacrifice an animal as part of their observance, it is still a very popular tradition, even in Muslim communities in Europe). The meat would then be divided into three equal parts to be distributed to others. The family eats one third, another third is given to other relatives, friends or neighbours, and the other third is given to the poor as a gift.
Eid al-Adha is celebrated annually on the 10th day of the month of Dhul Hijja of the lunar Islamic calendar. The festivities last for three days or more depending on the country. Eid al-Adha celebrations start after the Hajj, the annual pilgrimage to Mecca in Saudi Arabia by Muslims worldwide, descend from Mount Arafat. The date is approximately 70 days after the end of the month of Ramadan.
Easter
Easter is a moveable feast, meaning it is not fixed in relation to the civil calendar. The First Council of Nicaea (325) established the date of Easter as the first Sunday after the full moon (the Paschal Full Moon) following the northern hemisphere's vernal equinox. Ecclesiastically, the equinox is reckoned to be on March 21 (regardless of the astronomically correct date), and the "Full Moon" is not necessarily the astronomically correct date.
The date of Easter therefore varies between March 22 and April 25. Eastern Christianity bases its calculations on the Julian Calendar whose March 21 corresponds, during the twenty-first century, to April 3 in the Gregorian Calendar, in which calendar their celebration of Easter therefore varies between April 4 and May 8.
