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).

Commemorates the January 9, 1964 riots over sovereignty of the Panama Canal Zone. The riots erupted after a Panamanian flag was torn down during conflict between Panamanian students and U.S. citizens living in the Panama Canal Zone over the right of the Panamanian flag to be flown alongside the U.S. flag. United States' Army units became involved in suppressing the violence after Canal Zone police were overwhelmed. After three days of fighting, 22 Panamanians and four U.S. citizens were killed.

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.

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

Panama was founded on August 15, 1519, by the Spanish conquistador Pedro Arias de Ávila. The city was the starting point of expeditions that conquered the Inca Empire in Peru (1532). It was a stopover point of one of the most important trade routes in the history of the American continent leading to the fairs of Nombre de Dios and Portobelo, where most of the gold and silver that Spain took from the Americas passed through. The city was destroyed by a devastating fire, when the pirate Henry Morgan sacked it on January 28, 1671. It was rebuilt and formally established on January 21, 1673, in a peninsula located 8 km from the original settlement. The place where the previously devastated city was located is still in ruins, and has become a tourist attraction known as "Panama Viejo".

The flag of Panama was made by Maria Ossa de Amador. It has been officially adopted by the "ley 48 de 1925"; the flag is celebrated on November 4, one day after Panamanian independence from Colombia. The first flag proposed in 1823 consisted of 7 horizontal stripes of red and yellow, with a blue canton containing 2 golden suns, joined by a narrow line to depict the oceans to be united by the Panama Canal (see the depiction below). However, this was not accepted by the Panamanian leader, Manuel Amador Guerrero, whose family designed a new flag. The stars and quarters are said to stand for the rival political parties, and the white for the peace in which they operate. Blue was the color of the Conservatives, and red the color of the Liberals.

On the 10th of November 1821 citizens of Los Santos passed a resolution calling for Los Santos' secession from Spain. This resolution led to the rest of Panamá to declare independence less than two decades later.

Christmas Eve is the day before Christmas Day, a widely celebrated holiday commemorating the birth of Jesus of Nazareth. It is a culturally significant celebration for most of the Western world and is widely observed as a full or partial holiday in anticipation of Christmas. In Western culture, Christmas Eve is celebrated on December 24. However, the Coptic, Serbian, Russian, Macedonian, and Georgian Orthodox Churches, as well as the Greek Orthodox Church of Jerusalem, use the Julian calendar, which is currently thirteen days behind the Gregorian calendar, so Christmas Eve for the adherents of those Churches coincides with January 6 of the following year in the Gregorian calendar.

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
