Date 12-26-05
What
day was a certain date?
To calculate the day on which a particular date falls, the following
algorithm may be used (the divisions are integer divisions, in which
remainders are discarded). On June 7, 1958, date = 6, month = 7, year
= 1958. Note that "mod" means the remainder when doing integer
division, e.g., 20 mod 7 = 6. That is, 20 divided by 7 is 2 and 6/7th
(where six is the remainder).
a = [(14 - month) / 12]
y = year - a
m = month + 12 a - 2
For Julian calendar:
day = (5 + date + y + y/4 + [31 m / 12]) mod 7
For Gregorian calendar:
day = (date + y + y/4 - [y / 100] + [y / 400] + [31 m/ 12]) mod 7
Where day 0 is Sunday, day 1 is Monday, etc...
Notes:
November 10, 1975
= Monday
Phases of the moon
= 1/2

On November 9, 1975 at 7:01
p.m. the National Weather Service (NWS) issued a gale warning for Lake
Superior. In a gale, the wind speeds range from 34 - 40 knots. The NWS
predicted east to northeasterly winds during the night, shifting to
NW to N by the afternoon of November 10, 1975. At approximately 10:35
p.m. the NWS revised its forecast for eastern Lake Superior to easterly
winds becoming southeasterly the morning of the 10th. At about 2:00
a.m. November 10, 1975 the NWS upgraded the gale warning to a storm
warning (winds 48 - 55 knots) with a prediction of "northeast winds
35 to 50 knots becoming northwesterly 28 to 38 knots on Monday, waves
8 to 16 feet". Around 2:10 a.m. the Captains of the Anderson and
Fitzgerald discussed the threatening weather and decided to change their
route. This safer route would take them northward, toward the coast
of Canada. The northern route would protect them from the waves that
the storm generated.
