Please, memorise 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 + mon no . + (x-1900) + (x-1900)/4.
x = the year we have to calculate.
Eg:
16-may-2011.
for = 16 + 2 + (2011-1900) + (2011-1900)/4,
= 16+2+111+111/4.
= 16+2+111+27.
(here we should not take the no behind decimal i.e 111/4=27.75)
= 156.
156/7 = 2(reminder).
Mon = 2.

Ans :-
Step 1 ; how many years we have between 2006 to 2010 = 2006 - 2010 =4.
Step 2 ; per year 365 so if we divide by weeks = 365/7 = 52.1 that means 52weeks 1ood days.
Step 3 ; So every 4th year we have an extra day that we call leap year means 366 days again if we divide by weeks = 366/7 = 52.2 in this 2 ood days we have.
Step 4; 2006 = 1.
For 2007 = 1.
For 2008 = 1.
For 2009 = 2 (1+1+1+2 = 5days).
Step 5;
1 jan 2006 = Sunday count 1 .
1 jan 2007 = Monday count 1.
1 jan 2008 = Tuesday count 1.
1 jan 2009 = Wednesday & Thursday count 2 because as per our count it is leap year(2days extra).
1 jan 2010 = answer is Friday.
