Julian Equinoxes/epochs
A Julian epoch is an epoch that is based on Julian years of exactly 365.25 days. Since 1984, Julian epochs are used in preference to the earlier Besselian epochs.
Julian epochs are calculated according to:
- J = 2000.0 + (Julian date − 2451545.0)/365.25
The standard equinox and epoch currently in use are J2000.0, which corresponds to January 1, 2000 12:00 Terrestrial Time.

Famous quotes containing the words julian and/or epochs:
“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)
“There are lone figures armed only with ideas, sometimes with just one idea, who blast away whole epochs in which we are enwrapped like mummies. Some are powerful enough to resurrect the dead. Some steal on us unawares and put a spell over us which it takes centuries to throw off. Some put a curse on us, for our stupidity and inertia, and then it seems as if God himself were unable to lift it.”
—Henry Miller (1891–1980)
