If 6th March, 2005 is Monday, what was the day of the week on 6th March, 2004?
Sunday
Saturday
Tuesday
Wednesday
Answer: Option
Explanation:

The year 2004 is a leap year. So, it has 2 odd days.

But, Feb 2004 not included because we are calculating from March 2004 to March 2005. So it has 1 odd day only.

The day on 6th March, 2005 will be 1 day beyond the day on 6th March, 2004.

Given that, 6th March, 2005 is Monday.

6th March, 2004 is Sunday (1 day before to 6th March, 2005).

Guys even you can find through vedic maths.

I show you there are codes for solving calendar problems:

Months:

Jan (1) , feb (4) , mar (4) , apr (0) , may (2) , jun (5) , jul (0) , aug (3) , sep (6) , oct (1) , nov (4) , dec (6). Learn it through any trick.

Weeks:

Sun (1), mon (2), tues (3) fri (6), satur (0 or 7).

Start:

Check if condition: 6th march 2005.

Step : 6 (date) + 4 (march code) + 05 (year) + 05 (date) /4 = 6+4+5+1 = 16/7 = 2 odd days means (monday) but year is 20th century so, -1 is apply that's means 2 - 1 = 1 odd day which means sunday. But option said monday that's means add +1 means 1+1 = 2 odd days (monday).

Check then condition: 6th march 2004.

Step : 6 (date) + 4 (march code) + 04 (year) + 04 (year) /4 = 6+4+4+1 = 15/7 = 1 odd days means (sunday) but year is 20th century so, -1 is apply that's means 1-1 = 0 odd (saturday) but 2004 is leap year means again -1 that's means 6 odd (friday) but from if condition we add +1 at last according to question. It means we will +1 here also then 6 + 1 = 7 or 0 odd day means saturday.

All the best guys.

This is an easy way to solve that all problems:

***********************************************
It is used to solve all problems. I have given below.

2004>>>is a leap year 366days ,feb-29-1 odd day
100 years>>> 5odd day.
200years>>>3 odd day.
300 years>>> 1odd day.
400 years>>> 0 odd day.

Month of total 31 days means>>>3 odd day.
Month of total 30 days means>>>2odd day.
Month of total 28 days means>>>0 odd day.
we go to solve that problem>>>>>>
********************************************************************

Solution:

6th march 2004
>>>>we seperated to add year.

1. 1600+400+3yr+(jan+feb)+6days.
|
400=0,4*400=1600,3yr we check how many leap year& ordinary year 3/4=not divisible So take 3 are odd.

2.0+0+3(1-odd)+(3+0)+6.
3.14 /7.
4.2 weeks 0 odd day.
5.we know 0 odd day is sunday.

So the answer is SUNDAY.

@All.

Note : Their is "if" Written in question,
Means we need to assume that in
6th march, 2005 is Monday.


Points to remember:-
1)

5th march, 2004 --- 6th march 2005 is
Equivalent to 1 year.
Means starting day and ending day is
Same for basic year.
Thus;

5th march 2004=6th march 2005= Monday.
For basic year;
6th march 2004 = Monday -1= Sunday.
Here, 1 means one day back.

2) For leap year.
Monday-2

Read question carefully,
If it is written in question that 2000 is not a leap year,
Then we need to assume it.

Hope it will help you.

The given answer is Correct.

The given data is 'If 6th March, 2005 is Monday' - here we have to consider it as Monday (but actually 6th March, 2005 is Sunday).

As per the calculation 6th March, 2004 is one before to 6th March 2005.

Therefore, one day before to 'Monday' is 'Sunday'.

Note: Please do not check the with the original calendar to find the day of 6th March, 2004. Because the given data is an assumption.

Request: Please think twice before post your doubts here.

Hope you are all understand it well. Have a nice day!

There we need to follow 6 steps

1. Last two digits of the year in given is 04
2. Divide by 4 of the year is 01
3. Take the date in given is 06
4. Take the month in given is 03 (according to the formulas)
5. Take the year in given is 06.
(Add all the values - 04+01+06+03+06=20).
6. Divided by 7 of the values of 20 is 06

Here 06 is the value but we have one odd day in the year, let we add that the odd day in it is 06+01 = 07.

Hence the answer is 07 which means it is Sunday.
(*0 or 07 is same)

Step1: No.of odd days 2000=0.
Step2: No.of odd days 400=0.
Step3: No.of odd days (2001-2003)=3.
Step4: No.of odd days (Jan=31+Feb=29+march=6)=66-(9 weeks+3 days)=3. Total No.of odd days=0+0+3+3=6.
Monday=1.
6+1=7. Is 0 answer is Sunday.

Nanthakumar said:   3 months ago
The Correct answer is Sunday because this is calculate only 2005 march - 2004 march not included February.

For example; if the year consider leap year the February month 29 day.
But if the year consider non leap year the February month 28 days only.

Therefore 2005 is non leap year and this contains only 1 odd day.
But 2004 is leap year therefore this year contains 2 odd day but February month not included therefore this month same 1 odd days i.e Monday - 1= Sunday.

Hi @Roji I can explain by your formula.

Day+Month code+(x-1990)+(x-1990)/4.

Step 1: First you should calculate the day for the first mentioned date.

i.e 4 for 6th march 2005.

[6+4+105+26=141/7 it should be Sunday since rem is 1].

But it was given Monday so it is shifted by one day.

Step 2: If you calculate for 6th mar' 2004 you will get Saturday.

So to get answer you should shift the obtained answer by one day. It works for all problems.

Solve - 6th march 2004.

March = 25/4 = 1
April = 30/4 = 2
May = 31/4 = 3
June = 30/4 = 2
July = 31/4 = 3
August = 31/4 = 3
September = 30/4 = 2
October = 31/4 = 3
November = 30/4 = 2
December = 31/4 = 3

6th March = 2005
January = 31/4 = 3
February = 28/4 = 0

6 day consider or march
=1+2+3+2=8(8-7=1), 1+3+3=7(7-7=0), 0+2+3+2=7, (7-7=0), 0+3+3+2=8, (8-7=1) Now we add 6 days of march 2005.

6+1 = 7(7-7 = 0) 0 Means Sunday.

Avinash Kumar (Hajipur) said:   7 years ago
Find 6 March 2004 what will the Day ?

So, 2004 we consider last two digit then 04 also than add in 100 ; 100+04=104 i.e 26.

Again we add 104+26(and given Month is March so a.c to this we can add 3) +03+(given date is 06);

FInally add: 104+26+03+06 = 139.

Again 139 is divided by 7;

So 139/7 remainder is 06.

Result is 0 is Sunday, 01 Mon, 02,Tues, 04 wed, 05 Thu; 06 sat;
So final ans is 06 (Saturday).

Thank You.
