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 falls near major holidays, 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 potentially less precise method is to take the number of the date of the birthday and advance the month by six: e.g. December 5 becomes June 5. Because not all months have the same number of days, this method does not always work – for example, six months after an August 30 birthday would be February 30, which is nonexistent in the Gregorian calendar. The more precise method is to add or subtract half the number of days in a year to the birth date. In the case of a common year, this wo ...

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, and Krishna Janmashtami). There is a distinction between birth''day'' and birth''date'': 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). Legal conventions 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 enli ...

February 30
Several non-standard dates are used in calendars. Some are used sarcastically, some for scientific or mathematical purposes, and some for exceptional or fictional calendars. January 0 January 0 or 0 January is an alternative name for December 31. In an ephemeris 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. In software In Microsoft Excel, the epoch of the 1900 date format is January 0, 1900. February 30 February 30 or 30 February is a date that does not occur on the Gregorian calendar, where the month of February contains ...

Gregorian Calendar
The Gregorian calendar is the calendar used in most parts of the world. It was introduced in October 1582 by Pope Gregory XIII as a modification of, and replacement for, the Julian calendar. The principal change was to space leap years differently so as to make the average calendar year 365.2425 days long, more closely approximating the 365.2422-day 'tropical' or 'solar' year that is determined by the Earth's revolution around the Sun. The rule for leap years is: There were two reasons to establish the Gregorian calendar. First, the Julian calendar assumed incorrectly that the average solar year is exactly 365.25 days long, an overestimate of a little under one day per century, and thus has a leap year every four years without exception. The Gregorian reform shortened the average (calendar) year by 0.0075 days to stop the drift of the calendar with respect to the equinoxes.See Wikisource English translation of the (Latin) 1582 papal bull '' Inter gravissimas''.

Individual Retirement Account
An individual retirement account (IRA) in the United States is a form of pension provided by many financial institutions that provides tax advantages for retirement savings. It is a trust that holds investment assets purchased with a taxpayer's earned income for the taxpayer's eventual benefit in old age. An individual retirement account is a type of individual retirement arrangement as described in IRS Publication 590, ''Individual Retirement Arrangements (IRAs)''. Other arrangements include employer-established benefit trusts and individual retirement annuities, by which a taxpayer purchases an annuity contract or an endowment contract from a life insurance company. Types There are several types of IRAs: * Traditional IRA – Contributions are often tax-deductible (often simplified as "money is deposited before tax" or "contributions are made with pre-tax assets"), all transactions and earnings within the IRA have no tax impact, and withdrawals at retirement are taxed as income ...

Driver's Licenses In The United States
In the United States, driver's licenses are issued by each individual state, territory, and the District of Columbia rather than by the federal government due to federalism. Drivers are normally required to obtain a license from their state of residence and all states recognize each other's licenses for non-resident age requirements. There are also licenses for motorcycle use. Generally, a minimum age of 16 is required to obtain a driver's or motorcycle license, and 18 for a commercial driver's license which is required for operating heavy size vehicles (buses, trucks, tractor-trailers) or vehicles with at least 16 passengers or hazardous materials. A state may also suspend an individual's driving privilege within its borders for traffic violations. Many states share a common system of license classes, with some exceptions, e.g. commercial license classes are standardized by federal regulation at . Many driving permits and ID cards display small digits next to each data field. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 w ...
