Here is the trick to get the day of 200 years calendar 1900 to 3000. You can also say the trick by the Phonetic method!
First, there are three Table that has to remember, are as-
| January | 1 |
|---|---|
| February | 4 |
| March | 4 |
| April | 0 |
| May | 2 |
| June | 5 |
| July | 0 |
| August | 3 |
| September | 6 |
| October | 1 |
| November | 4 |
| December | 6 |
Table 2
| Sunday | 1 or 0 |
|---|---|
| Monday | 2 |
| Tuesday | 3 |
| Wednesday | 4 |
| Thursday | 5 |
| Friday | 6 |
| Saturday | 7 |
Table 3
TRICK:-
So let’s Get started!
We have to Find the day of a given Date.
We have to follow these steps –
First, we write the code of Month, year, and that day and add that!
Ex.- 19 august 1967 So, 19 + 3 + 6 = 28 (Get these code in the above table Given)
Step 2:-
Now we divide that no. by 7
Ex:- we got the no. 28 so I divide it by 7 (28 ÷ 7)
We got Reminder as ‘0’
So, We got ‘0’ as that code so we look for it in Table 1 (Upside), We looked in the table this code is on Saturday.
Thus,
The final answer is Saturday!
Note:-
In January or February of a Leap Year, For finding the day, we have to take the previous day of our answer (Means if we got Monday as our answer so the final answer will be the previous day that is Sunday). It is due there are 366 days in Leap Year!
We have to find the day of 26 January 1920
So by Method , 26 + 1+ 4 = 31 then 31 ÷ 7 , remainder is 3. So 3 is the code of Tuesday but for our answer, we have to take a previous day that is Monday.
So, Monday is our final answer.
This Is the Method for finding the day of the 20th Century!
Example:-
For 21th Century:-
Similarly, In the 21st century, For finding the day we follow all the steps as we previously followed
But One more step we have to follow is that while getting the final answer by that method we have to take the previous day as the main answer!
For Example:-
10 January 2007
We know the code of 1907 so we use that code here
so, 10 + 1 + 1 = 12, dividing it by 7 we got remainder as 5 and is code of Thursday So for the final answer we take a previous day that is Wednesday as our answer
Thus, the final answer for 10 January 2007 is Wednesday
Note:-
In 21th Century, January and February months (Of Leap Year) We have too less 2 days in our answer. one of being leap and one of being of 21st century
For Ex. –
26 January 2020
26 + 1+ 4 = 31 ,dividing by 7 remainder is 3 that is code of Wednesday
For the final answer, we have to go two days before that is Monday!
Hope you Understood the trick!
