Understanding the YEAR before it changes !!!!

With the new year around the corner; having celebrated it for the eternity welcomed by people, the term made me restless. What exactly is a year; where did it come from ? This is what I found out: Read on...


The word "year" is also used of periods loosely associated but not strictly identical with either the astronomical or the calendar year, such as the seasonal year, the fiscal year or the academic year, etc.

The term year can mean the orbital period of any Planet, Venus completes its own orbit. The term is also applied more broadly to any long period or cycle, such as the "Great YearA year is the Orbital period of the Earth moving around the Sun. For an observer on the Earth, this corresponds to the period it takes the Sun to complete one course throughout the Zodiac along the elliptic. In astronomy, the Julian year is a unit of time, defined as 365.25 Days of 86400 SI Seconds each, however, there is no universally accepted symbol for the year as a unit of time.


The International System of Units does not propose one. A common abbreviation in international use is (for Latin annus), in English y or yr. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by changes in weather, hours of daylight, and consequently vegetation and fertility. Generally four seasons are considered: Summer, winter, autumn and Spring.



  • A fiscal or financial year is a 12-month period used for calculating annual financial statements in businesses and other organizations. In many jurisdictions, regulations regarding accounting require such reports once per twelve months, but do not require that the twelve months constitute a calendar year.

  • An academic year is the annual period during which a student attends an educational institution. The academic year may be divided into academic terms such as semesters or quarters. 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.

  • The Julian year, as used in astronomy and other sciences, is a time unit defined as exactly 365.25 days. This is the normal meaning of the unit "year" (symbol "a" from the Latin annus) used in various scientific contexts. The Julian century of 36525 days and the Julian millennium of 365250 days, by convention, the Julian year is used in the computation of the distance covered by a light-year.

  • The draconic year, draconitic year, eclipse year, or ecliptic year is the time taken for the Sun (as seen from the Earth) to complete one revolution with respect to the same lunar node (a point where the Moon's orbit intersects the ecliptic). This period is associated with eclipses: these occur only when both the Sun and the Moon are near these nodes; so eclipses occur within about a month of every half eclipse year. Hence there are two eclipse seasons every eclipse year.

  • The lunar year comprises twelve full cycles of the phases of the Moon, as seen from Earth. It has duration of approximately 354.37 days. Muslims use this for celebrating their Eids and for marking the start of the fasting month of Ramdan.

  • 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. The vague year was used in the calendars of Ancient Egypt, Iran, Armenia and in Mesoamerica among the Aztecs and Maya, although the Aztecs and Maya used 18 months of 20 days, plus a 5 day epagomenal month.

  • A heliacal year is the interval between the heliacal risings of a star. It differs from the sidereal year for stars away from the ecliptic due mainly to the precessions of equinoxes.

  • The Sothic year is the interval between heliacal risings of the star Sirius. It is currently less than the Sidereal year and its duration is very close to the mean Julian year of 365.25 days.

  • The Gaussian year is the side real year for a planet of negligible mass (relative to the Sun) and unperturbed by other planets that is governed by the Gaussian gravitational constant. Such a planet would be slightly closer to the Sun than Earth's mean distance

  • The Besselian calender is a tropical year that starts when the (fictitious) mean Sun reaches an ecliptic longitude of 280°.This is currently on or close to January 1. It is named after the 19th-century German astronomer and mathematician Friedrich Bessel.

  • The Green year speed is variable.

  • The Galactic year is the time it takes Earth's solar system to revolve once around the galactic center. It comprises roughly 230 million Earth years.


My My....so much for just one word....


May this new year take you beyond the horizon of happiness, Joy, abundance of laughter you wished for.

More importantly, may you be bestowed with all the strength to do what you wish and yearn to do.
