to find the day of the week is very easy........
you just follow the following steps
step1: just divide last 2 digits of the year that you want to find the day of the week with 12
ex:2nd oct 2009
09/12=0
step2:divide the remainder with 4
rem=9
9/4=2
step3:add all the values of steps1,2,&3
0+9+2=11
step4:divide the answer with 7,so simple then it is easy to calculate the date
11/7=4
remember the following days they are called doomsdays
1st write the even months and odd months
1,3,5,7,9,11 and 2,4,6,8,10,12
the even months start with the same no as the month are doomsdays
i.e ....4april,6thjune,8th august,10thoct,12thdecember are start in same day and
9th may--5thseptember
11thjuly--7thnovember are start in same day
these are called doomsdays and this days of the weeks are same.....
Dooms years table for u
1900-1999: wednessday
2000-2099: tuesday
2100-2199:monday
by remembering these days you can easyly find day of the week
our ex:
2nd oct 2009
we calculate the day for that date that is 4
add the day with the current years doomsday
for 2000-2099:tuesday
so tuesday+4=saturday
so the 2009 s doomsday is saturday
we know from mentioned above 10th oct is doomsday ,,,so it is saturday
go 8 days back to the date you can find that date
i.e 3rd oct is saturday...so 2nd oct is friday
