Catholic or protestant : Since pre-historic times in Europe, festivities (bonfires, offrerings) were marking the beginning of longer hours of daylight with fires and ritual. The Roman festival of Saturnalia lasted several days in December (gambling and offerings). Germanic tribes also celebrated mid-winter (drinking and rituals). The Bulgarian (with Koleduvane) and the Polish (with Gwiazdka) perpetuate this tradition. Jesus of Nazareth was probably born in springtime (Reformists favour autumn). But in the 4th century, December 25th was chosen for the celebration of his birth by Pope Julius I (Bishop Liberus is also mentioned in 354 A.D.). Thus, a Christian element was introduced in the long-established mid-winter festivals. Before 1582, the Papal States and other Italian city states celebrated New Year’s Day on Christmas Day.

Secular holiday : It was the Lahore Session of the Indian National Congress at midnight of December 31, 1929 - January 1, 1930, that the Tri-Colour Flag was unfurled by the nationalists and a pledge taken that every year on January 26, the Independence Day would be celebrated and that the people would unceasingly strive for the establishment of a Sovereign Democratic Republic of India. The professed pledge was successfully redeemed on January 26, 1950, when the Constitution of India framed by the Constituent Assembly of India came into force, although the Independence from the British rule was achieved on August 15, 1947. It is because of this that August 15 is celebrated as Independence Day, while January 26 as Republic Day.

Catholic or protestant : The First Council of Nicaea (a gathering of bishops in the early days of Christianity) wanted to find a day to commemorate the crucifixion and resurrection of Christ. This commemoration had to be linked to Jewish holiday traditions, since the last supper of Christ was believed to be a Jewish Passover meal. But the Jewish calendar is based on lunar and solar cycles, so the Easter celebration had to follow the same calendar.
