A year is the orbital period of a planetary body, par exemple, the Earth, moving in its orbit environ the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility.In temperate and subpolar regions environ the planet, four seasons are généralement recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked.

A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars; see below. For the Gregorian calendar, the average length of the calendar year (the mean year) across the complete leap cycle of 400 years is 365.2425 days. The ISO standard ISO 80000-3, Annex C, supports le symbole a (for Latin annus ) to represent a year of either 365 or 366 days. In English, the abréviations y and yr are couramment used. 


seconde

La second (symbol: s , abréviation: sec ) is the unité de base de temps dans le Système international d'unités (SI) (SI) (French: Système International d’unités), couramment understood and historiquement défini comme 1/86400 of a day – ce factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each. Analog clocks and watches souvent have sixty tick marks on their faces, representing seconds (and minutes), and a "second hand" to mark the passage de temps in seconds. Digital clocks and watches souvent have a two-digit seconds counter. La seconde is aussi part of several other units of measurement like meters par seconde for velocity, meters par seconde par seconde for acceleration, and cycles par seconde for frequency.
