Sunday in the context of "Coronations of the kings and queens of Jerusalem"

In Christianity, the Lord's Day refers to Sunday, the traditional day of communal worship. It is the first day of the week in the Hebrew calendar and traditional Christian calendars. It is observed by most Christians as the weekly memorial of the resurrection of Jesus Christ, who is said to have been raised from the dead early on the first day of the week. The phrase appears only once in Rev. 1:10 of the New Testament.

According to Beckwith, Christians held corporate worship on Sunday in the 1st century (First Apology, chapter 67). On 3 March 321, Constantine the Great legislated rest on the pagan holiday Sunday (dies Solis). Before the Early Middle Ages, the Lord's Day became associated with Sabbatarian (rest) practices legislated by Church Councils. Christian denominations such as the Reformed Churches, Methodist Churches, and Baptist Churches regard Sunday as the Christian Sabbath, a practice known as first-day Sabbatarianism. First-day Sabbatarian (Sunday Sabbatarian) practices include attending morning and evening church services on Sundays, receiving catechesis in Sunday School on the Lord's Day, taking the Lord's Day off from servile labour, not eating at restaurants on Sundays, not Sunday shopping, not using public transportation on the Lord's Day, not participating in sporting events that are held on Sundays, as well as not viewing television and the internet on Sundays; Christians who are Sunday Sabbatarians often engage in works of mercy on the Lord's Day, such as evangelism, as well as visiting prisoners at jails and the sick at hospitals and nursing homes. A Sunday custom present in many Christian countries is the "hearing" (abhören) of children at dinnertime, in which the parents listen while the children recall what their pastor preached about in the Sunday sermon; if any corrections are needed, the parents instruct them.

In the liturgical calendar of the Roman Rite, a solemnity is a feast day of the highest rank celebrating a mystery of faith such as the Trinity, an event in the life of Jesus, his mother Mary, his legal father Joseph, or another important saint. The observance begins with the vigil on the evening before the actual date of the feast. Unlike feast days of the rank of feast (other than feasts of the Lord) or those of the rank of memorial, solemnities replace the celebration of Sundays outside Advent, Lent, and Easter (those in Ordinary Time).

The word comes from postclassical Latin sollemnitas, meaning a solemnity, festival, celebration of a day.

Palm Sunday is the Christian moveable feast that falls on the Sunday before Easter. The feast commemorates Christ's triumphal entry into Jerusalem, an event mentioned in each of the four canonical Gospels. Its name originates from the palm branches waved by the crowd to greet and honor Jesus Christ as he entered the city. Palm Sunday marks the first day of Holy Week; in Western Christianity, this is the beginning of the last week of the solemn season of Lent, preceding Eastertide, while in Eastern Christianity, Holy Week commences after the conclusion of Great Lent.

In most Christian rites, Palm Sunday is celebrated by the blessing and distribution of palm branches (or the branches of other native trees), representing the palm branches that the crowd scattered before Christ as he rode into Jerusalem. These palms are sometimes woven into crosses. The difficulty of procuring palms in unfavorable climates led to the substitution of branches of native trees, including box, olive, willow, and yew.

In Abrahamic religions, the Sabbath (/ˈsæbəθ/) or Shabbat (Biblical Hebrew: שַׁבָּת [ʃa'bat]) is a day set aside for rest and worship. According to the Book of Exodus, the Sabbath is a day of rest on the seventh day commanded by Yahweh to be kept as a holy day of rest as God rested in the Genesis creation narrative. Shabbat observance is commanded in the Ten Commandments: "Remember the sabbath day, to keep it holy". The Sabbath might have been influenced by Babylonian mid-month rest days and lunar cycles, though its origins remain debated.

A day of rest is observed in Islam (Friday), Judaism (Saturday), and Christianity (Sunday). Observances similar to or descended from the Sabbath also exist in other religions. The term may be generally used to describe similar weekly observances in other religions.

Saturday is the day of the week between Friday and Sunday. No later than the 2nd century, the Romans named Saturday diēs Sāturnī ("Saturn's Day") for the god Saturn. His planet, Saturn, controlled the first hour of that day, according to Vettius Valens. The day's name was introduced into West Germanic languages, and is recorded in the Low German languages such as Middle Low German satersdach, saterdach, Middle Dutch saterdag (Modern Dutch zaterdag), and Old English Sæternesdæġ, Sæterndæġ or Sæterdæġ.

The weekdays and weekend are the complementary parts of the week, devoted to labour and rest, respectively. The legal weekdays (British English), or workweek (American English), is the part of the seven-day week devoted to working. In most of the world, the workweek is from Monday to Friday and the weekend is Saturday and Sunday. A weekday or workday is any day of the working week. Other institutions often follow this pattern, such as places of education. The constituted weekend has varying definitions, based on determined calendar days, designated period of time, and/or regional definition of the working week (e.g., commencing after 5:00 p.m. on Friday and lasting until 6:00 p.m. on Sunday). Sometimes the term "weekend" is expanded to include the time after work hours on the last workday of the week.Weekdays and workdays can be further detailed in terms of working time, the period of time that an individual spends at paid occupational labor.

In many Christian traditions, Sunday is the "day of rest and worship". The Jewish Shabbat or Biblical Sabbath lasts from sunset on Friday to the fall of full darkness on Saturday; as a result, the weekend in Israel is observed on Friday to Saturday. Some Muslim-majority countries historically instituted a Thursday–Friday weekend. Today, many of these countries, in the interests of furthering business trade and cooperation, have shifted to Friday–Saturday or Saturday–Sunday.

A leap year starting on Saturday is any year with 366 days (i.e. it includes 29 February) that begins on Saturday, 1 January, and ends on Sunday, 31 December. Its dominical letters hence are BA. The most recent year of such kind was 2000, and the next one will be 2028 in the Gregorian calendar or, likewise 2012 and 2040 in the obsolete Julian calendar. In the Gregorian calendar, years divisible by 400 are always leap years starting on Saturday. The most recent such occurrence was 2000 and the next one will be 2400, see below for more.

Any leap year that starts on Saturday has only one Friday the 13th: the only one in this leap year occurs in October. Common years starting on Sunday share this characteristic, but also have another in January. From August of the common year preceding that year until October in this type of year is also the longest period (14 months) that occurs without a Friday the 13th. Common years starting on Tuesday share this characteristic, from July of the year that precedes it to September in that type of year.

A common year starting on Sunday is any non-leap year (i.e. a year with 365 days) that begins on Sunday, 1 January, and ends on Sunday, 31 December. Its dominical letter hence is A. The most recent year of such kind was 2023, and the next one will be 2034 in the Gregorian calendar, or, likewise, 2018 and 2029 in the obsolete Julian calendar, see below for more.

Any common year that starts on a Sunday has two Friday the 13ths: those two in this common year occur in January and October.

Orthros (Greek: ὄρθρος, meaning "early dawn" or "daybreak") or útrenya (Slavonic ѹ́тренѧ) in the Byzantine Rite of the Eastern Orthodox Church and the Eastern Catholic Churches, is the last of the four night offices (church services), the other three being vespers, compline, and midnight office. Traditionally, in monasteries it is held daily so as to end immediately following sunrise, in contrast to parishes where it is held only on Sundays and feast days. It is often called matins after the office it most nearly corresponds to in Western Christian churches.

Orthros is the longest and most complex of the daily cycle of services. It is normally held in the early morning, often — always in monasteries — preceded by the midnight office, and usually followed by the First Hour. On great feasts it is held as part of an all-night vigil commencing the evening before, combined with an augmented great vespers and the first hour. In the Russian tradition, an all-night vigil is celebrated every Saturday evening, typically abridged, however, in spite of its name, to as short as two hours. In the Greek parish tradition, orthros is typically held immediately prior to the beginning of the divine liturgy on Sunday and feast day mornings.
