@All.
Here is the clarification.
Most of us have no prob in calculating no. Off odd days.
But confusion is there when considering the day code.
Simple;
1jan 2000 -sundays.
To
1jan 2006.
Odd days = 6.
2006 = 1.
2007 = 1.
2008 = 2.
2009 = 1.
1 jan 2006 so one day =one odd day.
Total=6
Odd day=7-6=1.
Starting day is sunday so again start from sunday then keep increasing by one
For odd 2=
1 = Monday,
2 = Tuesdays .
So on.

There was only one leap year and the difference of years is 4 now add 1 leap year (eg. 4+1).
Answer is 5 so add five to Sunday it became Friday.

FROM 2007 Normal year- 1 0dd day.
2008 leap year- 2 odd days.
2009 & 2010 normal year - 1 & 1 odd day.
add all the odd numbers= 5 odd days.
Sunday+ 5 odd day= Friday.
2008 leap year- 2 odd days.
2009 & 2010 normal year - 1 & 1 odd day.
add all the odd numbers= 5 odd days.
Sunday+ 5 odd day= Friday.

@All.
Leap year means February has 29 days.
The last leap year was 2020.
Leap year comes every 4 years.
Eg;
2004, 2008, 2012,2016,2020,2024.

Odd days in 1800 = 1800/7.
Thus we get quotient 52 and remainder 1.
So, the number of odd days in 1800 = 1 odd day.
Thus we get quotient 52 and remainder 1.
So, the number of odd days in 1800 = 1 odd day.
