Year (Leap)

A leap year è a calendar year containing one additional day — February 29 — added to keep the calendar year synchronized with the astronomical solar year. In the Gregorian calendar, a year è a leap year if divisible by 4, except for century years not divisible by 400. Un leap year equals exactly 366 days o 31,622,400 seconds. 


secondo

La second (simbolo: s , abbreviazione: sec ) è the unità base di tempo nel Sistema Internazionale di Unità (SI) (French: Système International d’unités), commonly understood e historically definito as 1/86400 of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes e finally to 60 seconds each. Analog clocks e watches often hanno sixty tick marks on their faces, representing seconds (and minutes), e a "second hand" to mark the passage di tempo in seconds. Digital clocks e watches often hanno a two-digit seconds counter. Il secondo è also part of several other units of measurement like meters al secondo for velocity, meters al secondo al secondo for acceleration, e cycles al secondo for frequency.
