Question 1

What is this topic?

Accepted Answer

Birthdays are more than cake: Taiwan uses both completed age and traditional age and often marks longevity from sixty; Japan legally moved away from kazoedoshi while retaining milestones such as kanreki; in the U.S., ages 16, 18, and 21 unlock different rights. India may distinguish the Gregorian date from a tithi, Indonesia often makes syukuran about sharing, and Brazil has the festa de 15 anos. This guide compares dates, age systems, food, gifts, and family rituals without treating one birthday format as universal.

Question 2

When is it?

Accepted Answer

There is no single verified fixed date here; timing varies by place, household, or personal choice.

Question 3

How do places mark it?

Accepted Answer

United States; Brazil; China; Indonesia; India; Japan; Taiwan

Question 4

What differs by place?

Accepted Answer

Brazil: Birthdays in Brazil follow the Gregorian date, and the most emblematic is the festa de 15 anos — a girl's coming-of-age party with a waltz, the changing of shoes and formal dress, sometimes on the scale of a wedding, though some families choose a trip instead. Everyday birthdays bring the parabéns sung in chorus, brigadeiros and a bolo, with offices and classrooms breaking into a round on the spot. It is common in Brazil for the person having the birthday to do the treating rather than to be treated. Outside the fifteenth-birthday party, the point of an ordinary birthday is the parabéns: the cake is only cut once the whole room has sung it through. China: Mainland China's Civil Code defines majority and legal capacity by completed years, and official documents use that count throughout. The traditional count remains in everyday use, though, especially in the north and in rural areas, when older relatives ask an age, when the zodiac sign is worked out, or when a date is chosen. Milestone banquets tend to start at sixty, seventy or eighty, and where the custom of marking the ninth rather than the tenth is kept, the banquet is held a year early. Longevity noodles are the common element; the cake was added later. Both the Gregorian and the lunar birthday are usually remembered for the same person, and which one is kept tends to be decided by the elders in the household. Indonesia: Birthdays in Indonesia follow the Gregorian date, and the weight of the occasion often sits on thanksgiving and sharing rather than on receiving: many households hold a syukuran — a blessing and a shared meal — and send food to neighbours and to people in need. Some prepare a tumpeng, the cone of turmeric rice, with the person whose birthday it is cutting the tip and giving it to whoever they most wish to honour. Celebrations at school and work look closer to the international default: a cake and a photograph. Because the weight is on sharing, birthday spending often goes on what is prepared for other people rather than on what one receives. India: Birthdays in India often carry two dates: the Gregorian one, and the one derived from the tithi, the lunar day, in the Hindu lunisolar calendar — and the two do not coincide from year to year. Rituals at home usually follow the tithi: a blessing, a puja at the temple, touching the feet of elders. School and workplace go by the Gregorian date. Turning sixty and turning eighty carry dedicated ceremonies in some communities, marking a change of life stage, and can be nearly as large as a wedding. Touching the feet of elders and a visit to the temple on the day are more often treated as the necessary step than cutting a cake is. Japan: Japan ended the coexistence of two age systems by statute: the Act on Stating Age, promulgated in 1949, called on the public to abandon the habit of stating age by the traditional count and instead to use the completed years calculated under the Age Calculation Act — months where less than a year — and required national and local government bodies to state age that way. It came into force on 1 January 1950. The traditional count was pushed out by legislation rather than fading on its own. Birthdays today are kept on the Gregorian date, usually with a cake and candles. Milestone ages carry their own names: sixty is kanreki, seventy koki, seventy-seven kiju, each with its own colour and its own way of being marked. Taiwan: In Taiwan, age is legally counted from the day of birth under Article 124 of the Civil Code — that is, completed years. But the traditional reckoning is still in daily use: fortune telling, birth-chart readings and older relatives asking your age often use it, which puts you one or two years older. So the same person on the same day can have two ages, depending on who is asking. Milestone birthdays generally start at sixty and are often kept on the lunar date; longevity noodles, red eggs and a cake coexist, with no single agreed form. There is no fixed rule about gifts; what people remember are the avoidances built on homophones — no clocks, no umbrellas — rather than any positive rule. United States: In the United States there is only one way to count a birthday and no statutory ritual, but age itself is sliced up by thresholds: a driving licence at sixteen, voting and contracting at eighteen, buying alcohol at twenty-one, with further state-level rules on top. So 'how old' functions in the United States as a series of switches for rights. Celebration ranges from cupcakes handed round a classroom to a party at home to a sweet sixteen or a twenty-first night out, with the scale entirely up to the family. A birthday in the United States is also a key administrative field: the driving licence, voter registration, insurance and every age limit key off it.
