Total days passed from 8th Feb 2005 - 9th Feb 2004 is 366 days.
Therefore, the number of odd days is 2.
Meaning 9th Feb is a Wednesday(1 = Same day, 2 = Next day and so on). So, 8th Feb 2004 has to be Tuesday.

@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.

Guys 8th Feb 2004 is Sunday.

But by using the formula.

Day = Date+Month code+(x-1990)+(x-1990) /4.

We are not getting it as Sunday.

Can anyone explain what is problem with our formula and what went wrong?

Feb is included(as we know a leap year contains 2 odd days, Here when we are going backward from 8th feb 2005 to 8th feb 2004,it includes the feb month ) i.e 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.

Same calender repeats if it is.
1) leap year=+28yrs.
2) leap+1 year=+6yrs.
3) leap+2years=+11yrs.
4) leap+3year=+11yrs.
For exa. -.
1984=leap year.
Same calender repeats on 2012.

According to me, the Correct answer is MONDAY.

Because the previous year is one day before next year so if 8th Feb 2005 is Tuesday then 8th feb 2004 will be Monday.

It is simple date given 8th feb 2005, a 366 days before date is 8th feb 2004. Simple divide 366/7, we get 2 remainder. Then subtract 2 days from tuesday its sunday.

Using formula, It is not correct The answer is monday.

So I didn't understand. So Please explain it by using the formula like day+ month No.+ X-1900+X-1900/4.
