also juke-box, "machine that automatically plays selected recorded music when a coin is inserted," 1939, earlier jook organ (1937), from jook joint "roadhouse, brothel" (1935), African-American vernacular, from juke, joog "wicked, disorderly," a word in Gullah (the creolized English of the coastlands of South Carolina, Georgia, and northern Florida). This is probably from an African source, such as Wolof and Bambara dzug "unsavory." The adjective is said to have originated in central Florida (see "A Note on Juke," Florida Review, vol. vii, no. 3, spring 1938). The spelling with a -u- might represent a deliberate attempt to put distance between the word and its origins.

For a long time the commercial juke trade resisted the name juke box and even tried to raise a big publicity fund to wage a national campaign against it, but "juke box" turned out to be the biggest advertising term that could ever have been invented for the commercial phonograph and spread to the ends of the world during the war as American soldiers went abroad but remembered the juke boxes back home.

"pertaining to or derived from Julius Caesar, 1590s, originally and especially in reference to the calendar system that began with his reforms in 46 B.C.E. (superseded by the Gregorian). The masc. proper name is from Latin Iulianus, from Iulius. The Julianists were a sect of Monophysites who held the body of Christ to be incorruptible; they were named for their leader, Julian, bishop of Halicarnassus (early 6c.).

Julian period, a period of 7,980 Julian years proposed by Joseph Scaliger in 1582 as a universal standard of comparison in chronology, consisting of the years of the solar and lunar cycles and the cycle of the indiction multiplied into each other (28 x 19 x 15). The first years of these cycles coincided in the year 4713 B.C., from which the period is reckoned. The first year of the Christian era being found by calculation to correspond to the year 4714 of the Julian period, all previous and subsequent comparisons can be made by simple subtraction or addition. This period is still used in the computations of chronologists and astronomers. [Century Dictionary, 1899]
