|a chronological period of 7,980 years, combining the solar, lunar, and indiction cycles (28 x 19 x 15 = 7,980), being reckoned from the year 4713 B. C., when the first years of these several cycles would coincide, so that if any year of the period be divided by 28, 19, or 15, the remainder will be the year of the corresponding cycle. The Julian period was proposed by Scaliger, to remove or avoid ambiguities in chronological dates, and was so named because composed of Julian years.|
