HI PEEPS!
let's put away all emo stuff at the moment ya?
at a bookstore at changi airport yesterday, i have discovered this REALLY interesting math book!
it's called 'think like a math genius'.
and i found this section whereby you can calculate the day from the date=)
just imagine, when your friend asks you like" eh, what is the day on 23 may 2011?"
you don't even need to wait for the calendar, because with only a series of codes, which i plagarised from the book, i can easily tell you that the date falls on a monday!
hard to believe?
fret not, i'm here to share with u the secret of this so-called theory allowing you to calculate any day from 2000 to 2020 just by knowing the date and a series of codes!
to begin, we need to know the codes for the days of the week, preeeeeetty easy aye?
monday-1
tuesday-2
wednesday-3
thursday-4
friday-5
saturday-6
sunday-7 or 0
next here comes the code for the months of a year which i have already committed them to memory=)
jan-6
feb-2
mar-2
apr-5
may-0
june-3
july-5
aug-1
sept-4
oct-6
nov-2
dec-4
in short, just rmb 622503514624.
however, there are certain exceptions to it, the exceptions only occur in a leap year!
in a leap year, jan-5 while feb-1
leap years are 2000, 2004, 2008, 2012, 2016, 2020!
next! the part which i plagarised from the book.heeeheee
2000-0
2001-1
2002-2
2003-3
2004-5
2005-6
2006-0
2007-1
2008-3
2009-4
2010-5
2011-6
2012-1
2013-2
2014-3
2015-4
2016-6
2017-0
2018-1
2019-2
2020-4
at this moment, dont faint.
HAHA.
yuppy, after knowing all the codes,
the golden formula is
month code+date+year code= DAY!
one example! let's try the today's date!
today is 9th march!
month code for march is 2
so,
2+ 9+ 4(the code for 2009 is 4)= 15
since the days of the week repeats itself,
we take 15-( the highest multiple of 7 that cannot exceed 15)=
15-14=1
since mon-1,
TODAY IS A MONDAY!!!!
another example, let's try 1st march 2009
2+1+4=7
7 ,according to our codes, is A SUNDAY!!
last example, let's try a harder one!
21 apr 2010
5(month code for apr)+21+5( year code)=31
31-(highest multiple of 7 that cannot exceed 31)=
31-28=3
wed-3
SO ITS A WEDNESDAY!!!
quite easy right?
with this u can calculate your birthdays, special occasions without the use of a calendar!
NOW HURRY THANK ME THANK ME!!!
HAHA.lol
get those brain juices flowing peeps!
is it right to end a cycle of pain if it opens a new cycle of pain?
