A CALCULATION OF THE WEEKDAY
IN THE JULIAN CALENDAR   II D

According to Astronomer Thomas Harriot



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 1 B.C. is a thought year when Jesus Christ was born. This year is
a reference year to our present year counting. The numerical value of Year
1 B.C. (Before Christ) is 0 (zero). The years before Year 1 B.C. have got
a minus sign (-) in front of the year. The years after Year 1 B.C. have a
plus sign (+) or an omitted sign in front of the year, and is the same as
"Anno Domini" (A.D.).


The Year 0 (zero) Anno Domini (Year 0 A.D.) is not in this calendar variety.
