If 15 August 1947- Friday.

Then what will be 7 May 2019? Anyone solve this.

@Soumya.

6th Aug is Thursday it means 2nd Aug is Sunday.
After every 7 days, the same day will fall.
2nd Aug, 9th Aug,16th Aug, 23th Aug, 30th Aug are Sunday. It means a total of 5 Sunday in Aug.

It is very simple remeber these 2 basic terms:

1)whenever we go from general year to general year or leap year then add 1.
2)whenever we go from leap year to general year then add 2.

Now come to question:

Given Jan 1 , 2006 was Sunday then;
Jan 1, 2010 = ?.

So here we go;

2006(general year) to 2007(general year)=1
2007(general year) to 2008(leap year)=1
2008(leap year) to 2009(general year)=2
2009(general year) to 2010(general year)=1

Adding them=1+1+2+1=5.
now Jan 1, 2010 = sunday+5= Friday.

Hope you guys got it. It's very simple method.

2006 = 1(odd day).
2007 = 1(odd day).
2008 = 2(odd days-it is a leap year).
2009 = 1(odd day).

Total = 5(odd days).

Monday=1
Tuesday=2
Wednesday=3
Thursday=4
Friday=5
Saturday=6
Sunday=7/0

So now we consider 5 as Friday.

@Deepika.

If the given year is a non-leap year then the first day is the same as the last day of the year.

For leap year last day will be the next day of the starting day of the year.

Suppose five days before tomorrow was Wednesday. What day of the week was yesterday? Anyone answer it.

@S.YJoshua!

I think it was SATURDAY.

@All.

Simple tricks to find a leap year.

--The year not evenly divisible by 4 means-not a leap year.
--The year evenly divisible by 4(but not in 100 &400) means-is a leap year.
--The year evenly divisible by 4 and 100(but not in 400) means-not a leap year.
--The year evenly divisible by 4,100,400 means-is a leap year.

Hi, how does adding odd no. Of days give us the exact same date for the next year? for EG if 1st of Jan was Monday then do we need to add 5 to Monday? Please explain to me.

@Sumanth Geras.

If x is less than 1900. We get a negative value then what we do?

Could you please explain?
