The form of calendar first introduced in 46 bc by the Roman emperor Julius Caesar, after whom it is named. It was prepared in consultation with the Greek astronomer Sosigenes (1st century bc). Each month was assigned the number of days it has today, and a normal year had 365 days. To read Julian date printable calendar, follow the below method: 1. Suppose the date on the calendar is 23165. 2. The first two digits, 23, represent the year, whereas the three digits after that indicate the day of the year. 3.

In the Western world, we celebrate the New Year on January 1st because of Julius Caesar, whose eponymous Julian calendar began in Mensis Ianuarius (or Januarius) 45B.C.. The month of January is named after the Roman god Janus, who had two faces, one facing the future and the other the past. He was the god of beginnings, endings, and transitions The Julian Day Number so calculated will be for 0 hours, GMT, on that date. Here's how to do it: 1) Express the date as Y M D, where Y is the year, M is the month number (Jan = 1, Feb = 2, etc.), and D is the day in the month. 2) If the month is January or February, subtract 1 from the year to get a new Y, and add 12 to the month to get a new M The 304-day calendar year began in March (Martius), named after the Roman god Mars. But though the Julian calendar would stick around for centuries, the date of its new year wasn’t always Revised Julian calendar: 1923 CE: 365.242222 days: 2 sec/year (1 day in 31,250 years) Mayan calendar ~2000 BCE: 365.242036 days: 13 sec/year (1 day in 6500 years) Gregorian calendar: 1582 CE: 365.2425 days: 27 sec/year (1 day in 3236 years) Jewish calendar: 9th century CE: 365.246822 days: 7 min/year (1 day in 216 years) Julian calendar: 45 BCE In 44 bce, the second year of the Julian calendar, the Senate proposed that the name of the month Quintilis be changed to Julius (July), in honour of Julius Caesar, and in 8 bce the name of Sextilis was similarly changed to Augustus (August). Perhaps because Augustus felt that his month must have at least as many days as Julius Caesar’s T914.
