Julian Year (astronomy)
In astronomy, a Julian year (symbol: a) is a unit of measurement of time defined as exactly 365.25 days of 86,400 SI seconds each. The Julian year is the average length of the year in the Julian calendar used in Western societies in previous centuries, and for which the unit is named. Nevertheless, because an astronomical Julian year measures duration rather than designating a date, this Julian year does not correspond to years in the Julian calendar or any other calendar. Nor does it correspond to the many other ways of defining a year.

Famous quotes containing the words julian and/or year:
“The rich were dull and they drank too much or they played too much backgammon. They were dull and they were repetitious. He remembered poor Julian and his romantic awe of them and how he had started a story once that began, “The very rich are different from you and me.” And how someone had said to Julian, “Yes, they have more money.””
—Ernest Hemingway (1899–1961)
“We are playing with fire when we skip the years of three, four, and five to hurry children into being age six.... Every child has a right to his fifth year of life, his fourth year, his third year. He has a right to live each year with joy and self-fulfillment. No one should ever claim the power to make a child mortgage his today for the sake of tomorrow.”
—James L. Hymes, Jr. (20th century)
