A CALCULATION OF THE WEEKDAY
IN THE JULIAN CALENDAR   II C

According to Astronomer Jakob Christmann



This web page calculates the weekday corresponding to a particular date of
the Julian Calendar.

The web page only calculates the weekday, if the year is within the period
between year 45 B.C. and year 9 A.D.

The Year 0 (zero) is a thought year when Jesus Christ was born. This year
is a reference year to our present year counting. The years before Year 0
have got a minus sign (-) in front of the year and is the same as "Before
Christ" (B.C.). The years after Year 0 have a plus sign (+) or an omitted
sign in front of the year, and is the same as "Anno Domini" (A.D.).


In general "Year 0" is written as "Year 0 A.D.".
