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)
“But real action is in silent moments. The epochs of our life are not in the visible facts of our choice of a calling, our marriage, our acquisition of an office, and the like, but in a silent thought by the way-side as we walk; in a thought which revises our entire manner of life, and says,—”Thus hast thou done, but it were better thus.””
—Ralph Waldo Emerson (1803–1882)
