NAME

Calendar::Julian - Interface to Julian Calendar.

VERSION

Version 0.08

DESCRIPTION

The Julian calendar was proclaimed by Julius Cesar in 46 B.C. and underwent several modifications before reaching its final form in 8 C.E.The Julian calendar differs from the Gregorian only in the determination of leap years, lacking the correction for years divisible by 100 and 400 in the Gregorian calendar. In the Julian calendar, any positive year is a leap year if divisible by 4. (Negative years are leap years if the absolute value divided by 4 yields a remainder of 1.) Days are considered to begin at midnight.

In the Julian calendar the average year has a length of 365.25 days. compared to the actual solar tropical year of 365.24219878 days.The calendar thus accumulates one day of error with respect to the solar year every 128 years. Being a purely solar calendar, no attempt is made to synchronise the start of months to the phases of the Moon.
