👉 Birthday in the context of Birthday problem

In probability theory, the birthday problem asks for the probability that, in a set of n randomly chosen people, at least two will share the same birthday. The birthday paradox is the counterintuitive fact that only 23 people are needed for that probability to exceed 50%.

The birthday paradox is a veridical paradox: it seems wrong at first glance but is, in fact, true. While it may seem surprising that only 23 individuals are required to reach a 50% probability of a shared birthday, this result is made more intuitive by considering that the birthday comparisons will be made between every possible pair of individuals. With 23 individuals, there are 23 × 22/2 = 253 pairs to consider.

Birthday in the context of Jehovah's Witnesses

Jehovah's Witnesses is a nontrinitarian, millenarian, and restorationist Christian denomination, stemming from the Bible Student movement founded by Charles Taze Russell in the nineteenth century. Russell co-founded Zion's Watch Tower Tract Society in 1881 to organize and print the movement's publications. A leadership dispute after Russell's death resulted in several groups breaking away, with Joseph Franklin Rutherford retaining control of the Watch Tower Society and its properties. Rutherford made significant organizational and doctrinal changes, including adoption of the name Jehovah's witnesses in 1931 to distinguish the group from other Bible Student groups and symbolize a break with the legacy of Russell's traditions. In 2024, Jehovah's Witnesses reported a peak membership of approximately 9 million worldwide.

Jehovah's Witnesses are known for their evangelism, distributing literature such as The Watchtower and Awake!, and for refusing military service and blood transfusions. They consider the use of God's name vital for proper worship. They reject Trinitarianism, inherent immortality of the soul, and hellfire, which they consider unscriptural doctrines. Jehovah's Witnesses believe that the destruction of the present world system at Armageddon is imminent, and the establishment of God's kingdom over earth is the only solution to all of humanity's problems. They do not observe Christmas, Easter, birthdays, or other holidays and customs they consider to have pagan origins incompatible with Christianity. They prefer to use their own Bible translation, the New World Translation of the Holy Scriptures.

Birthday in the context of Gift

A gift or present is an item given to someone (who is not already the owner) without the expectation of payment or anything in return. Although gift-giving might involve an expectation of reciprocity, a gift is intended to be free. In many countries, the act of mutually exchanging money, goods, etc., may sustain social relationships and contribute to social cohesion. Economists have elaborated the economics of gift-giving into the notion of a gift economy. By extension, the term gift can refer to any item or act of service that makes the other happier or less sad, especially as a favor, including forgiveness and kindness. Gifts are often presented on occasions such as birthdays and holidays.

Birthday in the context of Party

A party is a gathering of people who have been invited by a host for the purposes of socializing, conversation, recreation, or as part of a festival or other commemoration or celebration of a special occasion. A party will often feature food and beverages, and generally conversation, music, dancing, or other forms of entertainment.

Some parties are held in honor of a specific person, day, or event, such as a birthday party, a Super Bowl party, or a St. Patrick's Day party. Parties of this kind are often called celebrations. A party is not necessarily a private occasion. Public parties are sometimes held in parks, restaurants, pubs, beer gardens, nightclubs, or bars, and people attending such parties may be charged an admission fee by the host. Large parties in public streets may celebrate events such as Mardi Gras or the signing of a peace treaty ending a long war.

Birthday in the context of Meal

A meal is an occasion that takes place at a certain time and includes consumption of food. The English names used for specific meals vary, depending on the speaker's culture, the time of day, or the size of the meal. A meal is different from a snack in that meals are generally larger, more varied, and more filling.

Though they can be eaten anywhere, meals usually take place in homes, restaurants, and cafeterias. Regular meals occur on a daily basis, typically several times a day. Special meals are normally held in conjunction with celebratory or momentous occasions such as birthdays, weddings, anniversaries, funerals, and holidays.

Birthday in the context of King's Official Birthday

The King's Official Birthday or Queen's Official Birthday is the selected day in most Commonwealth realms on which the birthday of the monarch is officially celebrated in those countries. It does not necessarily correspond to the date of the monarch's actual birth.

The sovereign's birthday was first officially marked in the Kingdom of Great Britain in 1748, for King George II. Since then, the date of the king or queen's birthday has been determined throughout the British Empire and, later, the Commonwealth of Nations, either by royal proclamations issued by the sovereign or viceroy, or by statute laws passed by the local parliament.

Birthday in the context of Eulogy

A eulogy (from εὐλογία, eulogia, Classical Greek, eu for "well" or "true", logia for "words" or "text", together for "praise") is a speech or writing in praise of a person, especially one who recently died or retired, or as a term of endearment.

Eulogies may be given as part of funeral services. In the United States, they take place in a funeral home during or after a wake; in the United Kingdom, they are said during the service, typically at a crematorium or place of worship, before the wake. In the United States, some denominations either discourage or do not permit eulogies at services to maintain respect for traditions. Eulogies can also praise people who are still alive. This normally takes place on special occasions like birthdays, office parties, retirement celebrations, etc. Eulogies should not be confused with elegies, which are poems written in tribute to the dead; nor with obituaries, which are published biographies recounting the lives of those who have recently died; nor with obsequies, which refer generally to the rituals surrounding funerals. Roman Catholic priests are prohibited by the rubrics of the Mass from presenting a eulogy for the deceased in place of a homily during a funeral Mass.
