Lets try the perpetual calender!



W Ξ k + [2.6m - 0.2] - 2C + Y + [Y/4] + [C/4] (mod 7)



k = day (by #) of the month

m = month of the year (by #, starting with March = 1, April = 2, May = 3,..., January = 11, Febuary = 12)

C = century (ex: if you want to look up a date in 1945, C = 19; if you want 1796, C = 17)

Y = year of the century (as the above examples, 1945, Y = 45, 1796, Y = 96)

[ ] denotes you take the whole number, with any decimal rounded down, [2.6] = 2, [3.4] = 3, [5.9] = 5

(mod 7) denotes that you round down if any number is 7 or higher... so 7 (mod 7) = 0, 11 (mod 7) = 4, 4 (mod 7) = 4



So... lets do my birthday. I was born July 12, 1984. Thursday the 12th :twisted: Evil comes a day early. Anyways...



k = 12, m = 5, C = 19, Y = 84



W Ξ 12 + [2.6(5) - .2] - 2(19) + 84 + [84/4] + [19/4] (mod 7)

W Ξ 12 + [12.8] - 38 + 84 + [21] + [4.75] (mod 7)

W Ξ 12 + 12 - 38 + 84 + 21 + 4 (mod 7)

W Ξ 95 (mod 7)

W = 4



So I was born on the 4th day of the week... Monday = 1, Tuesday = 2, Wednesday = 3, Thursday = 4. Oh, look, Thursday.



Now you know how people can tell you what day you were born on with just a date. Have fun and enjoy.
