A CALCULATION OF THE WEEKDAY
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 of the date is from
the year 10 A.D.
A little calendar historyThe imperator Julius Caesar commanded the Julian Calendar to be used as the
current calendar as from January, 1st of year 45 B.C. The calendar has got
its name after the imperator. Due to a misunderstanding about the usage of
leap year every third year instead of every fourth year, the correct usage
of the calendar was not until the year 5 A.D. That's why this web page only
calculates the weekday of a date from the year 5 and later.
In general up to the tenth centuary you didn't use the Birth of Christ as
the starting-point for year counting. Instead you counted years from the
time of the establishment of Rome. This establishment should have been
happened in April 21st, 753 B.C.
In the 11th centuary Sweden began to use the Julian Calendar. This calendar
was in current use up to February 28th, A.D. 1700. Between March 1st, 1700
and February 30th, 1712 (the Swedish Calendar) the authorities made an att-
empt to change the current calendar to the Gregorian Calendar. The time be-
tween March 1st, 1712 and February 17th, 1753 Sweden has again got the
Julian Calendar as the current calendar.
