On 8th Dec, 2007 Saturday falls. What day of the week was it on 8th Dec, 2006?
Answer: Option
Explanation:
The year 2006 is an ordinary year. So, it has 1 odd day.
So, the day on 8th Dec, 2007 will be 1 day beyond the day on 8th Dec, 2006.
But, 8th Dec, 2007 is Saturday.
8th Dec, 2006 is Friday.

After noticing many questions & problems based on this type. I finally observed these 2 key points which are:
1) We Subtract the day(s) number(odd or even) when we are asked in backward similarly.
2) We Add the the day(s)number(odd or even) when we are asked in forward.
eg:- For this question it was asked 8th dec 2006 providing 8th dec 2007.
Here goes the procedure:
Since neither 2006 nor 2007 is leap, we have ONE odd day.
As we are asked the day just subtract that ONE from the day given.
Implies we get Saturday-1=FRIDAY & that was the answer.

Why did we go back by one day? And not forward?
From saturday-> friday. Can't we go to sunday?

Every year divisible by 4 is a leap year. In your case 2006 is not divisible by 4, so it is not a leap year, hence it is an ordinary year.
One more thing is that; no century is a leap year...for example : 100, 200, 300, 500, 600, 700 and so on.......But every fourth century is a leap year...for example : 400, 800, 1200, 1600, 2000 so on.........
Please go through the formulas from the following link :

Cheerio!!
