Calendar year Definition & Meaning

Some schools in the UK, Canada and the United States divide the academic year into three roughly equal-length terms (called trimesters or quarters in the United States), roughly coinciding with autumn, winter, and spring. At some, a shortened summer session, sometimes considered part of the regular academic year, is attended by students on a voluntary or elective basis. Other schools break the year into two main semesters, a first (typically August through December) and a second semester (January through May). Each of these main semesters may be split in half by mid-term exams, and each of the halves is referred to as a quarter (or term in some countries). There may also be a voluntary summer session or a short January session.

There are typically 180 days of teaching each year in schools in the US, excluding weekends and breaks, while there are 190 days for pupils in state schools in Canada, New Zealand and the United Kingdom, and 200 for pupils in Australia.

Some schools in the United States, notably Boston Latin School, may divide the year into five or more marking periods.

Such seasonal variations in divisions of the day, now called seasonal or temporal hours, became customary in antiquity because they corresponded to the length of the Sun’s time above the horizon, at maximum in summer and at minimum in winter. Only with the advent of mechanical clocks in western Europe at the end of the 13th century did seasonal (unequal) hours become inconvenient. Although days are now measured from midnight to midnight, this has not always been so.

Later the Babylonians, Jews, and Greeks counted a day from sunset to sunset, whereas the day was said to begin at dawn for the Hindus and Egyptians and at midnight for the Romans. The Teutons counted nights, and from them the grouping of 14 days called a fortnight is derived. The calendar year is also called the civil year and contains a full 365 days or 366 for a leap year. The Gregorian calendar is the international standard and is used in most parts of the world to organize religious, social, business, personal, and administrative events. The vague year, from annus vagus or wandering year, is an integral approximation to the year equaling 365 days, which wanders in relation to more exact years. Typically the vague year is divided into 12 schematic months of 30 days each plus 5 epagomenal days.

Astronomers, for instance, from about the 2nd century ce until 1925, counted days from noon to noon.

Most primitive tribes used a dawn-to-dawn reckoning, calling a succession of days so many dawns, or suns.

Derived forms of calendar

Calendar, any system for dividing time over extended periods, such as days, months, or years, and arranging such divisions in a definite order. A calendar is convenient for regulating civil life and religious observances and for historical and scientific purposes. The development of a calendar is vital for the study of chronology, since this is concerned with reckoning time by regular divisions, or periods, and using these to date events. It is essential, too, for any civilization that needs to measure periods for agricultural, business, domestic, or other reasons.

The UCUM also minimizes confusion with are, a unit of area, by using the abbreviation “ar”. Financial and scientific calculations often use a 365-day calendar to simplify daily rates.

Astronomical years do not have an integer number of days or lunar months. Any calendar that follows an astronomical year must have a system of intercalation such as leap years. The seven-day week may owe its origin partly to the four (approximately) seven-day phases of the Moon and partly to the Babylonian belief in the sacredness of the number seven, which was probably related to the seven planets. Moreover, by the 1st century bce the Jewish seven-day week seems to have been adopted throughout the Roman world, and this influenced Christendom. The names in English of the days of the week are derived from Latin or Anglo-Saxon names of gods.

For example, seasonal businesses that derive the majority of their revenue during a certain time of the year often choose a fiscal year that best matches revenue to expenses.
