Reasoning Calender


 

Tricks to solve Quick Calendar reasoning questions

We have remember the days code, month code and century code to solve the questions on calendars.

Century Code:

1800 (1800 - 1899) - 2

1900 (1900 - 1999) - 0

2000 (2000 - 2099) - 6

2100 (2100 - 2199) - 4

 

Month Code:

January - 0

February - 3

March - 3

April - 6

May - 1

June - 4

July - 6

August - 2

September - 5

October - 0

November - 3

December - 5

 

Day Code:

Sunday - 0

Monday - 1

Tuesday - 2

Wednesday - 3

Thursday - 4

Friday - 5

Saturday - 6

 

Trick is:

  •  Date + Year

  • Century Code

  • Month Code

  • Year/4 (Take quotient value)

Note: You have to consider last two digits of a year.

 

eg:-

Model no :- 1

1. 28th July, 2019

Date + Year = (28 + 19) = 47

Century Code = 2000    = 06

Month Code = July        = 06

Year/4           = 19/4       = 04

Total                                = 63

Divide 63 with 7 (because there are 7 days in a week)

Consider the remainder value, remainder is 0.

So, 28th July, 2019 is Sunday.

 

2. 9th December, 2019

Year + date     = 28

Month code    = 05

Year/4             = 04

Century code = 06   

Total = 43

43/7 = remainder = 1

Day falls on Monday

 

3. 15th August, 1997

Date + year = 112

August        =    02

97/4            =    24

1997           =    00

Total = 138

138/7 = 5

15th August,1997 was on Friday

Note:- In a leap year, we have to reduce 1 day in the month of january and february.

 

Model no: 2

1. 15th January, 2008

Date + Year = 23

January = 00

8/4 = 02

2000 = 6

Total = 31

31/7 = 3

2008 - Leap year.....

So, We have to reduce 1 day.

3 - 1 = 2,

15th January, 2008 was on Tuesday.

 

Model no: 3

Repetition of Calendars

Note:- 

When we divide the year by 4, if 

  1. The remainder is 0, then substract 28 from the given year

  2. The remainder is 3, then add 11 to the given year

  3. The remainder is 1, then add 6 to the given year

 

eg:

1. The Calendar for the year 2007 will be same for the year????

Sol: Divide the year (07) with 4.

7/4 = 3, 

2007 + 11 = 2018.

 

2. For what year will​​​ the calendar be the same as for the year 2009?

Sol:- Divide the year 09 with 4.

Remainder is 1, so add 6 to the given year.

2009+06=2015 is the answer.

 

Note:-

     Last day of a century can't be tuesday, thurday and saturday.
