Why the no of odd days of the month of January is not counted?

I am not understanding, please explain to me, sir.

@All.

Normal year if (2013)- 1 odd day.
For leap year - 2 odd days .

I got Monday using year code and month code formula. Which is correct Sunday or Monday? please tell me.

2 March 2005 is Thursday then what day 12 November 2007?

Can anyone solve this?

Very nice answer @Bittu.

We are supposed to know the weekday on 8th Feb. 2004.

To all those who have doubt.

2004 = 1600 + 400 + 2001, 2002, 2003, (31 + 8 days of feb. ).
So odd days for the 1600 year = 0 odd days.
Odd days for 400 year = 0 odd days.
2001, 2002, 2003 all three are an ordinary year so odd days will be =3*1= 3 odd days.
And in 2004 total time period will be of 39 days ----> means 39/7= 5 weeks + 4 odd days.
So total odd days will be = 3+4= 7 (means 0 odd days).
So we finally got 0 odd days which means Sunday.

Hope you got it.

2000=0 odd day,
3 normal yr=3*1=3,
8 fabry= january 3 odd dys +8,
since day= 0+3+3+8=14/7=0.

The correct answer is Sunday.

Leap year means extra day in year which is 366. Since 2004 is leap year it has already surpassed day which would have been Sunday if it wasn't leap year. Correct answer is Monday.

@Shwetank Verma is correct it is Monday.

Hear in 2004 feb 8.

There is no need to sub extra odd day before feb 28. Because, we haven't crossed the extra day of year.

So subtracting 1 is correct i.e., Monday.
