Half-birthday
A half-birthday is a day approximately six months before or after the anniversary of a person's birth. It is sometimes marked by people whose birthday either falls on major holidays, near major holidays, or both, the celebration of which may overshadow celebration of the birthday. It may also be marked by students whose birthday does not occur during the regular school year; a half-birthday allows a celebration with friends at school, with half a cake. Calculation There are two ways to calculate half-birthdays. The easier but less precise method is to take the number of the date of the birthday and advance the month by six: e.g. April 20 becomes October 20. More than 75% of the time this method results in a wrong date. Months don't all have the same number of days, leap years add a day, and the second half of the year is longer than the first half. A good example where this doesn't work is six months after an August 30 birthday would be February 30, which is nonexistent in the G ...

Birthday
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, Krishna Janmashtami, and Gurpurb). There is a distinction between birth''day'' and birth''date'' (also known as date of birth): 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). Coming of age 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 School leaving age, full-time education, beco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
February 30
Several non-standard dates are used in calendars for various purposes: some are expressly fictional, some are intended to produce a rhetorical effect (such as sarcasm), and others attempt to address a particular mathematical, scientific or accounting requirement or discrepancy within the calendar system. Historical January 0 January 0 is an alternative name for December 31. January 0 is the day before January 1 in an annual ephemeris. It keeps the date in the year for which the ephemeris was published, thus avoiding any reference to the previous year, even though it is the same day as December 31 of the previous year. January 0 also occurs in the epoch for the ephemeris second, "1900 January 0 at 12 hours ephemeris time". 1900 January 0 (at Greenwich Mean Noon) was also the epoch used by Newcomb's ''Tables of the Sun'', which became the epoch for the Dublin Julian day. February 30 February 30 is a day that does not occur on the Gregorian calendar, where the month of F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gregorian Calendar
The Gregorian calendar is the calendar used in most parts of the world. It went into effect in October 1582 following the papal bull issued by Pope Gregory XIII, which introduced it as a modification of, and replacement for, the Julian calendar. The principal change was to space leap years slightly differently to make the average calendar year 365.2425 days long rather than the Julian calendar's 365.25 days, thus more closely approximating the 365.2422-day tropical year, "tropical" or "solar" year that is determined by the Earth's revolution around the Sun. The rule for leap years is that every year divisible by four is a leap year, except for years that are divisible by 100, except in turn for years also divisible by 400. For example 1800 and 1900 were not leap years, but 2000 was. There were two reasons to establish the Gregorian calendar. First, the Julian calendar was based on the estimate that the average solar year is exactly 365.25 days long, an overestimate of a li ...

Unbirthday
An unbirthday (originally written un-birthday) is an event celebrated on all days of the year which are not a person's birthday. It is a neologism which first appeared in Lewis Carroll's 1871 novel ''Through the Looking-Glass.'' The concept gave rise to "The Unbirthday Song" in the 1951 animated feature film ''Alice in Wonderland''. In ''Through the Looking-Glass'', Humpty Dumpty is wearing a cravat (which Alice at first mistakes for a belt) which he says was given to him as an "un-birthday present" by the White King and Queen. He then has Alice calculate the number of unbirthdays in a year. In the Disney animated film ''Alice in Wonderland'', Alice stumbles upon the Mad Hatter, the March Hare and the Dormouse having an unbirthday party and singing "The Unbirthday Song" (music and lyrics by Mack David, Al Hoffman and Jerry Livingston). Alice at first does not understand what an unbirthday is; when the Mad Hatter explains it to her, she realises it is ''her'' unbirthday as well ...
