A birthday is a day or anniversary when a person celebrates his or her date of birth. Birthdays are celebrated in numerous cultures, often with a gift, party or rite of passage. Although the major religions celebrate the birth of their founders (e.g., Buddha's Birthday), Christmas – which is celebrated widely by Christians and non-Christians alike – is the most prominent example. In contrast, certain religious groups, as is the case with Jehovah's Witnesses, express opposition to the very idea of celebrating birthdays.
Legal conventions
In most legal systems, one becomes a legal adult on a particular birthday (often between 14 and 21), and reaching age-specific milestones confers particular rights and responsibilities. At certain ages, one may become subject to military conscription or become eligible to enlist in the military, 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 license.
Cultural conventions
Many cultures have one or more coming of age birthdays:
- Jewish boys become bar mitzvah on their 13th birthday. Jewish girls become bat mitzvah on their 12th birthday, or sometimes on their 13th birthday in Reform and Conservative Judaism. This marks the transition where they become obligated in commandments of which they were previously exempted and are counted as part of the community.
- In North America, families often mark a girl's 16th birthday with a "sweet sixteen" celebration.
- In some Hispanic-American countries the quinceañera celebration traditionally marks a girl's 15th birthday.
- In India, Hindus have the 12th or 13th birthday replaced with a grand "thread ceremony." The child takes a blessed thread and wears it, symbolizing his coming of age. This is called the Upanayana. This ceremony is practiced amongst boys in the Hindu Brahmin culture.
- In the Philippines, girls on their 18th birthday or boys on their 21st birthday celebrate a debut.
- In some Asian countries that follow the Zodiac calendar, there is a tradition of celebrating the 60th birthday.
- In Japan there is a Coming of Age Day, for all of those who have turned 20.
The birthdays of historically significant people, like national heroes or founders, are often commemorated by an official holiday. Catholic saints are remembered by a liturgical feast (sometimes on a presumed birthday). By analogy, the Latin term Dies natalis is applied to the anniversary of an institution (such as a university).
A person's Golden or Grand Birthday, also referred to as their "Lucky Birthday", "Champagne Birthday" or "Star Birthday", occurs when they turn the age of their birth day (e.g., when someone born on the 25th of the month turns 25).
In many cultures and jurisdictions, if a person's real birthday is not known (for example, if he or she is an orphan), then their birthday may be considered to be January 1.
Birthday traditions
In many portions of the world 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. The celebrated individual makes a silent wish and attempts to blow out the candles in one breath; if successful, it means 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 his/her age. Other birthday activities include entertainment usually 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. An occasional activity is spanking the birthday individual, with one usually gentle "swat" for each year since birth.
Name days
In some historically Roman Catholic countries such as Italy, Spain, France, Poland, Russia, Romania, Bulgaria, Serbia, Slovakia, Czech Republic, Hungary, Greece, Lithuania, Latvia and throughout South America, it is common to have a 'name day'/'Saint's day'. It is celebrated in much the same way as a birthday, but 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 even the name of a feast, for example, Noel or Pascal (French for Christmas and "of Easter"); for one, Togliatti got Palmiro as first name because he was born on Palm Sunday.
Official birthdays
Some notables, particularly monarchs, have an official birthday on a fixed day of the year, which may not necessarily match their actual birthday, but on which celebrations are held. Examples are:
- Jesus Christ's traditional birthday is celebrated as Christmas Day around the world, on December 25. As some Eastern churches use the Julian calendar, December 25 will fall upon January 7 in the Gregorian calendar.
- The Queen's Official Birthday in Australia, Canada, Fiji, New Zealand, and the United Kingdom.
- The Grand Duke's Official Birthday in Luxembourg is typically celebrated upon June 23.
- Koninginnedag in the Kingdom of the Netherlands is typically celebrated upon April 30. Queen Beatrix fixed it at the birthday of her mother, the previous Queen, to avoid the winter weather associated with her own birthday in January.
- The current Japanese Emperor Akihito's birthday is December 23, which is a national holiday in Japan.
- The previous Japanese Emperor Showa (Hirohito)'s birthday was April 29. After his death, the holiday was kept as "Showa no Hi", or "Showa Day". This holiday falls close to Golden Week, the week in late April and early May
- The Muhammad's birthday in Indonesia is a national holiday in Indonesia.
- Kim Il-sung and Kim Jong-Il's birthday are celebrated in North Korea as a national holiday in North Korea.
Frequency
According to a public record births database, birthdays in the United States are quite evenly distributed for the most part. However, there tend to be more births in September and October. This may be because there is a holiday season nine months before, or from the fact that the longest nights of the year happen in the Northern Hemisphere nine months before as well. Based on Harvard University research of birth records 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).
how seasonably
leaf and blossom uncurl
and living things arrange their death,
while someone from afar off
blows birthday candles for the world.
— Irving Layton (b. 1912)
More recently October 5th and 6th have taken over as the most popular birthdays.
According to a study by Yale School of Public Health, positive and negative associations with culturally significant dates can influence birthrates. The study shows a 5.3 percent decrease in spontaneous births and a 16.9 percent decrease in cesarean births on Halloween, compared to other births occurring within one week before and one week after the October holiday. Whereas, on Valentine’s Day there is a 3.6 percent increase in spontaneous births and a 12.1 percent increase in cesarean births.
Time zones and birthdays
A person's birthday is usually recorded according to the time zone of the place of birth. Thus people born in American Samoa at 11:30 pm will record their birthdate as one day before Coordinated Universal Time (UTC) and those born in the Samoa will record their birthdate one day after UTC. They will apparently be born two days apart, while some of the apparently older ones may be younger in hours. Those who live in different time zones from their birth often exclusively celebrate their birthdays at the local time zone.

Birthdays in cultures and religions
Ancient Rome
The Romans enthusiastically celebrated birthdays with hedonistic parties and generous presents. In revulsion, the early Christians rejected the practice as inherently pagan.
Judaism
In Judaism, the perspective on birthday celebrations is disputed by various rabbis. In the Hebrew Bible, the one single mention of a celebration being held in commemoration of someone's day of birth is for the Egyptian Pharaoh which is recorded in Genesis 40:20. Rabbi Moshe Feinstein always acknowledged birthdays. According to Rabbi Yissocher Frand, a person's birthday is a special day for that person's prayers to be accepted.
The bar mitzvah of 13-year-old Jewish boys, or bat mitzvah for 12-year-old Jewish girls, is perhaps the only Jewish celebration undertaken in what is often perceived to be in coalition with a birthday. However, the essence of a bar/bat mitzvah celebration is entirely religious in origin (i.e. the attainment of religious maturity according to Jewish law) and not secular, despite modern celebrations where the secular "birthday" element often overshadows the essence of it as a religious rite. With or without the "birthday" celebration, the child nevertheless becomes a bar or bat mitzvah, and the celebration can be on that day or any date after it.
Christianity
Christianity: Early centuries
The early Christians did not celebrate Christ's birth because they considered the celebration of anyone's birth to be a pagan custom. For example Origen in his commentary "On Levites" writes that Christians should not only refrain from celebrating their birthdays, but should look on them with disgust.
Although I’m trying very hard
To sound unlike a birthday card,
That’s all this is: so you may find it
Full of all that lies behind it
Admiration; friendship too;
And hope that in the future you
Reap ever richer revenue.
— Philip Larkin (1922–1986)
Orthodox Christianity still prefers the celebration of name days only.
Christianity: Medieval
Ordinary folk celebrated their saint's day (the saint they were named after), but nobility celebrated birthdays. The "Squire's Tale," one of Chaucer's Canterbury Tales, opens as King Cambuskan proclaims a feast to celebrate his birthday.
Christianity: Modern
Jehovah's Witnesses and some Sacred Name groups refrain from celebrating birthdays on the basis that they are portrayed in a negative light in the Bible and have historical connections with magic, superstitions, and Paganism.
Islam
Conservative clerics consider the celebration of a birthday to be a sin, as it is considered an "innovation" of the faith, or bi'dah. A few Muslim clerics have issued statements saying that the celebration of a birthday is permissible.
Some Muslims (and Arabian Christians) migrating to the United States adopt the custom of celebrating birthdays, especially for children, but others resist.
There is also a great deal of controversy regarding celebrating Milad-ul-Nabi - the birth anniversary of Muhammad. While a section of Islam strongly favours it, others decry such celebrations, terming them as out of the scope of Islam.
Hindus
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.
Buddhism
Many monasteries celebrate the Buddha's birthday, usually in a highly formal, ritualized manner. They treat Buddha's statue as if alive, bathing and feeding it.
Sikhism
Sikhs celebrate Guru Nanak's Birthday.
North Korea
In North Korea, People don't celebrate birthdays on July 8 and December 17 because July 8 is the death day of Kim Il-sung, and December 17 is the death day of Kim Jong-Il. So, over 100000 residents in North Korea celebrate their fake birthdays on July 9 or December 18 to avoid these sad days, July 8 and December 17. If a person who was born on July 8 before 1994 changes their birthday, it will be officially recognised.
LaVeyan Satanism
The importance of birthdays in LaVeyan Satanism has been cited by several groups that do not celebrate birthdays, usually as an addition to their main arguments.
Superstitious origins of celebrations
A number of possible superstitious origins for customs associated with birthday celebrations have been suggested. One source states that the tradition of birthday parties started in Europe. It was feared that evil spirits were particularly attracted to people on their birthdays and to protect them, they would be visited by friends and family, who would bring good thoughts and wishes.
