Interesting enough, you can find the day of the week according to the date. I say interesting because the majority who ever wanted to find the day often use an app or even the calender on any device that allows you to change the date (like the tablet or gaming console). They never get a chance to understand the formula behind it. It's easy to figure this out.
Let's say you wanted to figured out the day for April 3, 2010. Here are the steps.
1) Divide the last two digits of the year by 4, and round to the nearest floor (hint: ditch the remainder).
2010 is the year, and thus, 10 is the last two digits. Divide it by 4, and you will have 2 with the remainder of 2 . . . since we are not using the remainder, the answer will be 2
2) Add the answer to the day of the date.
3 is the day, and so, 2 + 3 equals to 5
3) Add the answer to the number that corresponds to the month of the date.
Jan - 1
Feb - 4
March - 4
April - 0
May- 2
June - 5
July - 0
Aug - 3
Sept - 6
Oct -1
Nov - 4
Dec - 6
Since April is 0, the answer remains 5
4) Add the answer to the number that corresponds to the century of the date.
1700's - 4
1800's - 2
1900's - 0
2000's - 6
2100's -- 4
It's no doubt that the year is the 2000's, which makes the answer 11, considering that 5 + 6 = 11.
5) Add the answer again, only this time, to the last two digits of the year.
We are revisiting the last two digits of the year, which is 10, only this time, we are adding it to the answer 11. 11 + 10 = 21
6) Modulo divide the answer by 7. Then match up the result to find the day of the week.
Saturday - 0
Sunday - 1
Monday - 2
Tuesday - 3
Wednesday - 4
Thursday - 5
Friday - 6
By "modulo divide", it means to divide the two numbers to get the remainder as the answer. In this case, 21 / 7 equals to 3 with the remainder of 0. 21 % 7 is the same thing. With 0 for the remainder, April 3, 2010 is on a Saturday!
Now you know on how it works. It's easy once your figure it out yourself. Try it out on any date, including your birthdate.
Umm . . . you probably figured it out on why I have posted it. It still haunts me . . . It troubles me that someone claims that the release date for Sonic Advance 2 is March 12, 2003, not March 9, 2003. Whose right and wrong? So . . . I decided to check it out myself based on the day of the week when the two was released.
By using the steps to determine the day, I have come to this.
March 12, 2003
3 / 4 = 0
0 + 12 = 12
12 + 4 = 16
16 + 6 = 22
22 + 03 = 25
25 % 7 = 4
4 = Wednesday
It troubles me, because I don't remember that there was a time that games were released on a Wednesday. Maybe it happened, but then again, it may not, considering that common knowledge recalls that games are usually released in the U.S. on a Sunday or Monday. It would make sense consider that three days before that mentioned date, which is March 9, 2003, is on a Sunday!
I can prove that Sunday is a popular day for game releases by using the U.S. release date of Animal Crossing: City Folk, which happens to be the same date of my 24th birthday.
November 16, 2008
8 / 4 = 2
2 + 16 = 18
18 + 4 = 22
22 + 6 = 28
28 + 08 = 36
36 % 7 = 1
1 = Sunday
While at it, let's do an experiment to prove how reliable the formula that determines the day is. Let's use the release date of Sonic Advance 2 in Japan!
December 19, 2002
2 / 4 = 0
0 + 19 = 19
19 + 6 = 25
25 + 6 = 31
31 + 02 = 33
33 % 7 = 5
5 = Thursday
It's interesting to know that Thursday is the day when it was released in Japan. Why? Thursday has always been a tradition for game releases in Japan. It very noticeable considering Japan usually shipped anything electronic on a Thursday. It also explains why Wednesday is a bad day to shop at the Akihabara district of Tokyo.
Who is right or who is wrong? I only have experience to inform me. If everything I learn and experience is a lie, maybe I'm a lie myself. Maybe I don't exist . . . I wish that only for once I was right . . . Then again, maybe I don't really exist!
