What was the day of the week on 28th May, 2006?
Thursday
Friday
Saturday
Sunday
Answer: Option
Explanation:

28 May, 2006 = (2005 years + Period from 1.1.2006 to 28.5.2006)

Odd days in 1600 years = 0

Odd days in 400 years = 0

5 years = (4 ordinary years + 1 leap year) = (4 x 1 + 1 x 2) 6 odd days

Jan.  Feb.   March    April    May 
(31 +  28  +  31   +   30   +   28 ) = 148 days

148 days = (21 weeks + 1 day) 1 odd day.

Total number of odd days = (0 + 0 + 6 + 1) = 7 0 odd day.

Given day is Sunday.

Because in 100 years there are (96/4) =24 leap years and other72 years are ordinary days and as.

100 years (76 ordinary years + 24 leap years).

= (76 x 1 + 24 x 2) odd days,
= 124 odd days.
= (17 weeks + 5 days) ,
= 5 odd days.

Hence the number of odd days in 100 years = 5.

Number of odd days in 200 years = (5 x 2) = 10 -> 3 odd days.
Number of odd days in 300 years = (5 x 3) = 15 -> 1 odd days.
Number of odd days in 400 years = (5 x 4 + 1) = 21 -> 0 odd days.
Similarly, the number of odd days in all 4th centuries (400, 800, 1200 etc. ) = 0.

That is why we take 1600 & 400 instead of 1200, 800 etc. Numbers.

I'm not understanding the relation between 1600yrs & 400yrs.

Why not we can take 1200yrs & 800yrs instead of 1600yrs & 400yrs?

MONTH CODE.

J F M A M J J A S O N D
1 4 4 0 2 5 0 3 6 1 4 6

YEAR CODE = 2006 - 6.

Sun = 1, Mon = 2, T = 3, W = 4, Thurs = 5, Fri = 6, Sat = 7 or 0.

28/5/2006.
D + M + Y + Leap year + Cc.
28 + 2 + 6 + 1 + 6 = 43.

43/7 = Q = 6, Re = 1.

If we put 1990 instead of 1900 it will be right.

Why 1600 is grouping first?
