Date::Christmas calculates the day of the week that Christmas will fall upon in any given year after the year 1600AD, including leap years when using a Gregorian Calendar. The algorithm is based on ``The Formula for Christmas Day'' on pages 261-262 in the book _The Physics of Christmas_ by Roger Highfield.
``Other prognostications, not only of the weather, were based on the day of the week on which Christmas fell:
Sunday If the natiuity of our Lorde come on Sunday, Winter shall be good, the spring windy, sweet & hot, Vintage flourishing, Oxen and Sheepe multiplied: Hony & milke plentifull, peace and accord in the Land, yea, all the Sundayes in the yeere following profitable: They that bee borne shall be strong, great and shining: and he that flieth shall be found.
Monday If it fall on the Monday, Winter shall bee indifferent, Sommer dry, or clean contrary, so that if it be rainy and tempestuous, vintage shall be doubtfull; in each Munday of the said yeere, to enterprise any thing is shall bee prosperous and sstrong. Who that flieth shall soone be found: theft done shall be proued, and hee that falleth into his bed, soone recouer.
Tuesday If it come on the Tuesday, Winter shall be good, the spring windy, Summer fruitfull, Vintage laboursome, Weomen die and shippes perish on the Seas. In each Tuesday of this same yeere, to beginne a worke, it will prosper: hee that is borne shall be strong and couteous, dreames pertaine to age. Hee that flieth shall soone bee found; theft done shall be proued.
Wednesday If it come on the Wednesday, Winter shall be sharpe and hard, the Spring windy and euill, summer good, Vintage plentifull, good wit easily found, young men die, hony sparing, men desire to trauell, and ship-men saile with great hazard that yeere. In each Wednesday to begin a worke is good.
Thursday If it come on the Thursday, Winter shall bee good, the Spring windy, Summer fruitfull, Vintage plentifull. Kings and Princes in hazard. And in each Thursday to beginne a new worke, prosperous. Hee that is borne shall be of faire speech and worshipfull, hee that flieth shall soone be found: theft done by weomen shall be proued. Hee that falleth in his bed shall soone recouer.
Friday If it come on the Friday, winter shall be maruellous, the Spring windy and good, Summer dry, Vintage plenteous: There shall be trouble of the aire, Sheepe and Bees perish, Oates deare. In each Friday to begin a worke it shall prosper; hee that is borne shall be profitabe and lecherous. Hee that flieth shall soone be found; theft done by a Childe shall bee proued.
Saturday If it come on the Saturday, Winter shall be dark, snow great, fruit plentious, the spring windy, Summer euill, Vintage sparing in many places: Oates shall be deare, Men waxe sicke, and Bees die. In no Saturday to begin a worke shall be good, except in the course of the Moone alter it: Theft done shall be found, hee that flieth shall turne againe to his owne; those that are sicke, shall long waile, and vnneath they shall escape death. 'Godfridus', The knowledge of things vnknowne, 1-3" [The Oxford Companion to the Year, pp. 516-517.]
