Prince Kūhiō Day is an official holiday in the state of Hawaiʻi in the United States.^[1] It is celebrated annually on March 26, to mark the birth of Prince Jonah Kūhiō Kalanianaʻole — heir to the throne of the Kingdom of Hawaiʻi, prince of the House of Kalākaua, and later territorial delegate to the United States Congress.^[2] As Delegate, Kuhio authored the first Hawaii Statehood bill in 1919. He also won passage of the Hawaiian Homes Act, creating the Hawaiian Homes Commission and setting aside 200,000 acres (810 km²) of land for Hawaiian homesteaders.

It is one of only two holidays in the United States dedicated to royalty, the other being Hawaiʻi's King Kamehameha Day June 11.^[1]

The Slave Trade Act (citation 47 Geo III Sess. 1 c. 36) was an Act of Parliament of the United Kingdom passed on 25 March 1807, with the long title "An Act for the Abolition of the Slave Trade". The original act is in the Parliamentary Archives. The act abolished the slave trade in the British Empire, but not slavery itself; slavery on English soil was unsupported in English law and that position was confirmed in Somersett's Case in 1772, but it remained legal in most of the British Empire until the Slavery Abolition Act 1833.

The Committee for the Abolition of the Slave Trade formed in 1787 was formed by a group of Evangelical English Protestants allied with Quakers to unite in their shared opposition to slavery and the slave trade. The Quakers had long viewed slavery as immoral, a blight upon humanity. By 1807 the abolitionist groups had a very sizable faction of like-minded members in the British Parliament. At their height they controlled 35–40 seats. Known as the "Saints", the alliance was led by the best known of the anti-slave trade campaigners, William Wilberforce, who had taken on the cause of abolition in 1787 after having read the evidence that Thomas Clarkson had amassed against the trade.^[1] These dedicated Parliamentarians had access to the legal draughtsmanship of James Stephen, Wilberforce's brother-in-law. They often saw their personal battle against slavery as a divinely ordained crusade. On Sunday 28 October 1787, Wilberforce wrote in his diary: "God Almighty has set before me two great objects, the suppression of the slave trade and the reformation of manners."^[2]

Freedom Day is an unofficial holiday in Belarus, which is celebrated on March 25 to commemorate the creation on that date in 1918 of the Belarusian People's Republic (BPR).

People and groups opposed to the current Belarusian government under Alexander Lukashenko celebrate the holiday. The government does not recognize it for the stated reason that the BPR was created by the Germans, who were occupying Belarus in 1918. Celebrations of the holiday are an annual occasion of demonstrations against the rule of president Alexander Lukashenka.

Maryland Day is a legal holiday in the U.S. state of Maryland. It is observed on the anniversary of the March 25, 1634, landing of settlers in the Province of Maryland. On this day settlers from The Ark and The Dove first stepped foot onto Maryland soil, at St. Clement's Island in the Potomac River. The colony was granted to Cæcilius Calvert, 2nd Baron Baltimore two years prior by Charles I of England. In thanksgiving for the safe landing, Jesuit Father Andrew White celebrated mass for the colonists, perhaps for the first time ever in this part of the world. The landing coincided with the Feast of the Annunciation, a holy day honoring Mary, and the start of the new year in England's legal calendar (prior to 1752).

The holiday began in 1903, the date chosen by the state board of education to honor Maryland history. In 1916, the legislature authorized Maryland Day as a legal holiday (Chapter 633, Acts of 1916).

The Annunciation (anglicised from the Latin Vulgate Luke 1:36-39 Annuntiatio nativitatis Christi), also referred to as the Annunciation to the Blessed Virgin Mary or Annunciation of the Lord, is the Christian celebration of the announcement by the angel Gabriel to the Virgin Mary that she would conceive and become the mother of Jesus, the Son of God, marking his Incarnation. Gabriel told Mary to name her son Jesus, meaning "Saviour". Many Christians observe this event with the Feast of the Annunciation on 25 March, nine full months before Christmas, the birthday of Jesus. According to Luke 1:26, the Annunciation occurred "in the sixth month" of Elizabeth's pregnancy with John the Baptist.^[3]

Approximating the northern vernal equinox, the date of the Annunciation also marked the New Year in many places, including England, where it is called Lady Day. Both the Roman Catholic and Eastern Orthodox Churches hold that the Annunciation took place at Nazareth, but differ as to the precise location. The Basilica of the Annunciation marks the site preferred by the former, while the Greek Orthodox Church of the Annunciation marks that preferred by the latter.

An Independence Day is an annual event commemorating the anniversary of a nation's assumption of independent statehood, usually after ceasing to be a colony or part of another nation or state; more rarely after the end of a military occupation.

Most countries observe their respective independence days as a national holiday, and in some cases the observance date is controversial or contested. Not all countries observe an independence day holiday, choosing to celebrate other national days instead of or alongside an independence day.

Great Lent, or the Great Fast, is the most important fasting season in the church year in Eastern Christianity, which prepares Christians for the greatest feast of the church year, Pascha (Easter). In many ways Great Lent is similar to Lent in Western Christianity. There are some differences in the timing of Lent (besides calculating the date of Easter) and how it is practiced, both liturgically in the public worship of the church and individually.

One difference between Eastern Christianity and Western Christianity is the calculation of the date of Easter (see Computus). Most years, the Eastern Pascha falls after the Western Easter, and it may be as much as five weeks later; occasionally, the two dates coincide. Like Western Lent, Great Lent itself lasts for forty days, but unlike the West, Sundays are included in the count. Great Lent officially begins on Clean Monday, seven weeks before Pascha (Ash Wednesday is not observed in Eastern Christianity) and runs for 40 contiguous days, concluding with the Presanctified Liturgy on Friday of the Sixth Week. The next day is called Lazarus Saturday, the day before Palm Sunday. However, fasting continues throughout the following week, known as Passion Week or Holy Week, and does not end until after the Paschal Vigil early in the morning of Pascha (Easter Sunday).

Lent (Latin: Quadragesima, "fortieth"^[1]) is an observance in the liturgical year of many Christian denominations, lasting for a period of approximately six weeks leading up to Easter. In most Western denominations Lent is taken to run from Ash Wednesday to Maundy Thursday (Holy Thursday) or to Easter Eve.

The traditional purpose of Lent is the preparation of the believer—through prayer, penance, repentance, almsgiving, and self-denial. Its institutional purpose is heightened in the annual commemoration of Holy Week, marking the death and resurrection of Jesus, which recalls the events of the Passion of Christ on Good Friday, which then culminates in the celebration on Easter Sunday of the resurrection of Jesus Christ.
