@arun i cant get it pls explain it brief...

What is this odd day?

Can you explain it to me?

What is the odd day please explain briefly.

Is there any easiest method to calculate day plz i cant understood the odd day or even day

The number of days more than the complete weeks are called ODD DAYS....

In 400,1600,2000 odd days are zero...
****************************************************************
Day of the week on 28th may 2006,

In 2006,

Jan 31days+Feb 28days+Mar 31days+Apr 30days+May 28days[bcz 28th may]= 148days [totally]

To find odd day,
148/7=21quotient 1remainder

so 21complete weeks and 1 odd day in 2006

****************************************************************

For 5years [2001-2005],

To find leap year,
5/4=1 [never take the decimal points]
1leap year

So 2odd days in that year[366/7=52weeks+2odd days]
And rest of the 4years have 4odd days[365/7=52weeks+1odd day]

so for 5years,
2+4=6odd days

****************************************************************

Total number of odd days,

0+0+1+6=7

So, 7/7=1complete week
There is zero odd day in it.

0-Sunday
1-Monday
2-Tuesday
3-Wednesday
4-Thursday
5-Friday
6-Saturday


So 28th may 2006 is Sunday....:)

Well explained Senthil

Superb senthil. Chanceless.

Hi there is a formula for this type of problem.

Plz memorize this

jan=1
feb=4
mar=4
apr=0
may=2
jun=5
jul=0
aug=3
sep=6
oct=1
nov=4
dec=6

days:
s=1
m=2
t=3
w=4
th=5
f=6
sat=7 or 0

formula=day+month no.+(x-1900)+(x-1900)/4
x= the year we have to calculate

Eg:
28-may-2006

for=28+2+(2006-1900)+(2006-1900)/4
=28+2+16+16/4
=28+2+16+4 note:
=50 (here we should not take the no
behind decimal i.e 17/4=4.25)
50/7=1(reminder)

sun =1

@senthil

Why should we consider 2001-2005? they have specified only 2006.

@Deena

How come 2006-1900=16 can you tell me ?
