A birthday is the anniversary of the birth of a person, or figuratively of an institution. Birthdays of people are celebrated in numerous cultures, often with birthday gifts, birthday cards, a birthday party, or a rite of passage.
Many religions celebrate the birth of their founders or religious figures with special holidays (e.g. Christmas, Mawlid, Buddha's Birthday, and Krishna Janmashtami).
There is a distinction between birthday and birthdate: the former, except for February 29, occurs each year (e.g. January 15), while the latter is the complete date when a person was born (e.g. January 15, 2001).
In most legal systems, one becomes a legal adult on a particular birthday when they reach the age of majority (usually between 12 and 21), and reaching age-specific milestones confers particular rights and responsibilities. At certain ages, one may become eligible to leave full-time education, become subject to military conscription or to enlist in the military, to consent to sexual intercourse, to marry with parental consent, to marry without parental consent, to vote, to run for elected office, to legally purchase (or consume) alcohol and tobacco products, to purchase lottery tickets, or to obtain a driver's licence. The age of majority is the age when minors cease to legally be considered children and assume control over their persons, actions, and decisions, thereby terminating the legal control and legal responsibilities of their parents or guardians over and for them. Most countries set the age of majority at 18, though it varies by jurisdiction.
Many cultures have one or more coming of age birthdays:
The birthdays of historically significant people, such as national heroes or founders, are often commemorated by an official holiday marking the anniversary of their birth.
An individual's Beddian birthday, named in tribute to firefighter Bobby Beddia, occurs during the year that their age matches the last two digits of the year they were born.
In many cultures and jurisdictions, if a person's real birthday is not known (for example, if they are an orphan), then their birthday may be adopted or assigned to a specific day of the year, such as January 1. The birthday of Jesus is celebrated at Christmas. Racehorses are reckoned to become one year old in the year following their birth on the first of January in the Northern Hemisphere and the first of August in the Southern Hemisphere.
In many parts of the world,[vague] an individual's birthday is celebrated by a party where a specially made cake, usually decorated with lettering and the person's age, is presented. The cake is traditionally studded with the same number of lit candles as the age of the individual, or a number candle representing their age. The celebrated individual will usually make a silent wish and attempt to blow out the candles in one breath; if successful, a tradition holds that the wish will be granted. In many cultures, the wish must be kept secret or it won't "come true". Presents are bestowed on the individual by the guests appropriate to their age. Other birthday activities may include entertainment (sometimes by a hired professional, i.e. a clown, magician, or musician), and a special toast or speech by the birthday celebrant. The last stanza of Patty Hill's and Mildred Hill's famous song, "Good Morning to You" (unofficially titled "Happy Birthday to You") is typically sung by the guests at some point in the proceedings. In some countries a piñata takes the place of a cake.

In some historically Roman Catholic and Eastern Orthodox countries,[a] it is common to have a 'name day', otherwise known as a 'Saint's day'. It is celebrated in much the same way as a birthday, but it is held on the official day of a saint with the same Christian name as the birthday person; the difference being that one may look up a person's name day in a calendar, or easily remember common name days (for example, John or Mary); however in pious traditions, the two were often made to concur by giving a newborn the name of a saint celebrated on its birthday, or possibly the name of a feast, for example, Noel or Pascal (French for Christmas and "of Easter"); as another example, Togliatti was given Palmiro as his first name because he was born on Palm Sunday.
Some notables, particularly monarchs, have an official birthday on a fixed day of the year, which may not necessarily match the day of their birth, but on which celebrations are held. Examples are:
Birthdays are fairly evenly distributed through the year, with some seasonal effects.
In the United States, there tend to be more births in September and October. This may be because there is a holiday season nine months before (the human gestation period is about nine months), or because the longest nights of the year also occur in the Northern Hemisphere nine months before. However, it appears the holidays have more of an effect on birth rates than the winter: New Zealand, a Southern Hemisphere country, has the same September and October peak with no corresponding peak in March and April. The least common birthdays tend to fall around public holidays, such as Christmas, New Year's Day and fixed-date holidays such as July 4 in the US.
In the United States between 1973 and 1999, September 16 is the most common birthday in the United States and December 25 the least common birthday (other than February 29, because of leap years). In 2011, October 5 and 6 were reported as the most frequently occurring birthdays.
In New Zealand, the most common birthday is September 29, and the least common birthday is December 25. The ten most common birthdays all fall within a thirteen-day period, between September 22 and October 4. The ten least common birthdays (other than February 29) are December 24–27, January 1–2, February 6, March 22, April 1 and April 25. This is based on all live births registered in New Zealand between 1980 and 2017.
Positive and negative associations with culturally significant dates may influence birth rates. The study shows a 5.3% decrease in spontaneous births and a 16.9% decrease in Caesarean births on Halloween, compared to dates occurring within one week before and one week after the October holiday. In contrast, on Valentine's Day there is a 3.6% increase in spontaneous births and a 12.1% increase in Caesarean births.
In Sweden 9.3% of the population is born in March and 7.3% in November when a uniform distribution would give 8.3%.
In the Gregorian calendar (a common solar calendar), February in a leap year has 29 days instead of the usual 28, so the year lasts 366 days instead of the usual 365.
A person born on February 29 may be called a "leapling" or a "leaper". In common years, they usually celebrate their birthdays on February 28. In some situations, March 1 is used as the birthday in a non-leap year since it is the day following February 28.
Technically, a leapling will have fewer birthday anniversaries than their age in years. This phenomenon is exploited when a person claims to be only a quarter of their actual age, by counting their leap-year birthday anniversaries only. In Gilbert and Sullivan's 1879 comic opera The Pirates of Penzance, Frederic the pirate apprentice discovers that he is bound to serve the pirates until his 21st birthday rather than until his 21st year. For legal purposes, legal birthdays depend on how local laws count time intervals.
In Judaism, the rabbis are divided about celebrating this custom, although it was accepted by the majority of the faithful. In the Torah the only mention that is made of the birthday, refers to the celebration of Pharaoh's birthday in Egypt, as recorded in Genesis (Parashat Vaieshev) 40:20.
Origen in his commentary "On Levites" writes that Christians should not only refrain from celebrating their birthdays, but should look on them with disgust.
Ordinary folk celebrated their saint's day (the saint they were named after), but nobility celebrated the anniversary of their birth. The "Squire's Tale", one of Chaucer's Canterbury Tales, opens as King Cambuskan proclaims a feast to celebrate his birthday.
The Catholic Church, the Eastern Orthodox Church and Protestantism, accept birthdays as part of their traditional culture. Jehovah's Witnesses abstain from it for a number of reasons including its pagan origins, its rejection by early Christians, the way it is negatively expounded in the Holy Scriptures and the customs associated with superstition and magic.
The birthday does not reflect Islamic tradition, and because of this, the majority of Muslims refrain from celebrating it while for some it is not a problem, as long as it is not accompanied by behavior contrary to Islamic tradition. A good portion of Muslims, (and Arab Christians), who have emigrated to the United States and Europe, celebrate birthdays as customary especially for children, while some abstain. There is also much controversy regarding the permissibility of celebrating Mawlid, (the anniversary of the birth of Muhammad), as some Muslims judge the custom as an unacceptable practice according to Islamic tradition.
Main article: Buddha's birthday
Many monasteries celebrate the anniversary of Buddha's birth, usually in a highly formal, ritualized manner. They treat Buddha's statue as if it was Buddha himself, as if he were alive; bathing, and "feeding" him.
Hindus celebrate the birth anniversary day every year when the day that corresponds to lunar month or solar month (Sun Signs Nirayana System – Sourava Mana Masa) of birth and has the same asterism (Star/Nakshatra) as that of the date of birth. That age is reckoned whenever Janma Nakshatra of the same month passes.
Hindus regard death to be more auspicious than birth since the person is liberated from the bondages of material society. Also, traditionally, rituals & prayers for the departed are observed on 5th and 11th day with many relatives gathering.
Sikhs celebrate the anniversary of the birth of Guru Nanak.
According to Herodotus (5th century BC), of all the days in the year, the one which the Persians celebrate most is their birthday. It was customary to have the board furnished on that day with an ampler supply than common: the richer people eat wholly baked cow, horse, camel, or donkey (Greek: ὄνον), while the poorer classes use instead the smaller kinds of cattle.
The Romans enthusiastically celebrated birthdays with hedonistic parties and generous presents.

Chinese birthday traditions reflect the culture's deep-seated focus on longevity and wordplay. From the homophony between 酒 ("rice wine") and 久 (meaning "long" in the sense of time passing), osmanthus and other rice wines are traditional gifts for birthdays in China. Longevity noodles are another traditional food consumed on the day, although western-style birthday cakes are increasingly common among urban Chinese.
The Japanese really started celebrating birthdays after WWII based on Western influences. Children's birthday parties are the most important, with a cake, candles, and singing. Adults will often just celebrate with their partner.
In North Korea, people do not celebrate birthdays on July 8 and December 17 because these were the dates of the deaths of Kim Il-sung and Kim Jong-il, respectively. More than 100,000 North Koreans celebrate displaced birthdays on July 9 and December 18 to avoid these dates. A person born on July 8 before 1994 may change their birthday, with official recognition. Kim Il-sung's birthday, Day of the Sun, is the most important public holiday of the country, and Kim Jong-il's birthday is celebrated as Day of the Shining Star.
The beginning of life is heavily celebrated in South Korea. A child's first birthday is a momentous occasion. Also, an infant in South Korea is considered 1 year old. This is because January 1 is considered the birthday of every Korean person (see also East Asian age reckoning).
