Public holiday in the context of "Constitution of Ukraine"

A holiday is a day or other period of time set aside for festivals or recreation. Public holidays are set by public authorities and vary by state or region. Religious holidays are set by religious organisations for their members and are often also observed as public holidays in religious majority countries. Some religious holidays, such as Christmas, have become secularised by part or all of those who observe them. In addition to secularisation, many holidays have become commercialised due to the growth of industry.

Holidays can be thematic, celebrating or commemorating particular groups, events, or ideas, or non-thematic, days of rest that do not have any particular meaning. In Commonwealth English, the term can refer to any period of rest from work, such as vacations or school holidays. In American English, "the holidays" typically refers to the period from Thanksgiving to New Year's (late November to January 1), which contains many important holidays in American culture.

Christmas is an annual festival commemorating the birth of Jesus Christ, observed primarily on December 25 as a religious and cultural celebration among billions of people around the world. A liturgical feast central to Christianity, Christmas preparation begins on the First Sunday of Advent and it is followed by Christmastide, which historically in the West lasts twelve days and culminates on Twelfth Night. Christmas Day is a public holiday in many countries, is observed religiously by a majority of Christians, as well as celebrated culturally by many non-Christians, and forms an integral part of the annual holiday season.

The traditional Christmas narrative recounted in the New Testament, known as the Nativity of Jesus, says that Jesus was born in Bethlehem, in accordance with messianic prophecies. When Joseph and Mary arrived in the city, the inn had no room, and so they were offered a stable where the Christ Child was soon born, with angels proclaiming this news to shepherds, who then spread the word.

A patronal feast or patronal festival (Spanish: fiesta patronal; Catalan: festa patronal; Portuguese: festa patronal; Italian: festa patronale; French: fête patronale) is a yearly celebration dedicated – in countries influenced by Christianity – to the 'heavenly advocate' or 'patron' of the location holding the festival, who is a saint or virgin. The day of this celebration is called patronal feast day, patronal day or patron day of said location.

Patronal festivals may reflect national holidays (e.g. the feast of Saint George, patron saint of England, Georgia, Bulgaria, Romania, Portugal, and various regions of Spain), but they usually reflect the celebration of a single city or town.In larger cities, there may even be several festivals, usually about the patron saint of the local parish.

The Islamic New Year (Arabic: رأس السنة الهجرية, Raʿs as-Sanah al-Hijrīyah), also called the Hijri New Year, is the day that marks the beginning of a new lunar Hijri year, and is the day on which the year count is incremented. The first day of the Islamic year is observed by most Muslims on the first day of the month of Muharram. The epoch (reference date) of the Islamic era was set as the year of the emigration of Muhammad and his followers from Mecca to Medina, known as the Hijrah, which equates to 622 CE in the Gregorian calendar. All religious duties, such as prayer, fasting in the month of Ramadan, and pilgrimage, and the dates of significant events, such as celebration of holy nights and festivals, are calculated according to the Islamic calendar. Hijri New Year is observed by 24 countries as a public holiday.

While some Islamic organizations prefer determining the new month (and hence the new year) by local sightings of the moon, most Islamic institutions and countries, including Saudi Arabia, follow astronomical calculations to determine future dates of the Islamic calendar. There are various schemas for calculating the tabular Islamic calendar (i.e. not based on observation), which results in differences of typically one or even two days between countries using such schema and those that use actual lunar sightings. For example, the Umm al-Qura calendar used in Saudi Arabia was reformed several times in recent years. The current scheme was introduced in 1423 AH (15 March 2002).

A national day is a day on which celebrations mark the statehood or nationhood of a state or its people. It may be the date of independence, of becoming a republic, of becoming a federation, or a significant date for a patron saint or a ruler (such as a birthday, accession, or removal).

The national day is often an official public holiday. Many countries have more than one national day. Denmark and the United Kingdom are the only countries without a national day. Denmark has what is not a public holiday but an unofficial celebration called Constitution Day. National days emerged with the age of nationalism, with most appearing during the 19th and 20th centuries.

The Day of the Unification of the Romanian Principalities (Romanian: Ziua Unirii Principatelor Române) or, unofficially, the Little Union Day (Romanian: Ziua Micii Uniri), is a public holiday of Romania celebrated every 24 January to commemorate the unification of the Romanian Principalities (Moldavia and Wallachia), also known as the "Little Union", on 24 January 1859 under prince Alexandru Ioan Cuza. This event is deemed as important as it is considered the first step towards the goal of achieving a unitary Romanian state, something that is considered to have been achieved on 1 December 1918, when the Romanian National Assembly declared the union of Transylvania, Banat, Crișana, and Maramureș with the Kingdom of Romania.

The Day of the Unification of the Romanian Principalities was first adopted by the Senate on 2 June 2014 and later by the Chamber of Deputies on 3 December of the same year. The holiday became official when a few days later Romanian President Traian Băsescu signed a decree promulgating it on 16 December. Thus, Law No. 171/2014 dictates that, on 24 January, central and local authorities can provide material and logistical support to artistic and cultural events dedicated to this day. Since 2016, the observance is a non-working day in Romania.

Boxing Day, also known as Offering Day, is a holiday celebrated after Christmas Day, occurring on the second day of Christmastide (26 December). Boxing Day was once a day to donate gifts to those in need, but it has evolved to become a part of Christmas festivities. It originated in the United Kingdom and is celebrated in several Commonwealth nations. The attached bank holiday or public holiday may take place on 27 or 28 December if necessary to ensure it falls on a weekday. Boxing Day is also concurrent with the Christian festival Saint Stephen's Day.

In parts of Europe, such as east Spain, (Catalonia, Valencia and the Balearic Islands), the Czech Republic, Germany, Austria, Hungary, the Netherlands, Italy, Poland, Slovakia, Slovenia, Croatia, Denmark, Finland, Romania, Sweden, Belgium, Norway, Latvia and Ireland, 26 December is Saint Stephen's Day, which is considered the second day of Christmas.
