Vedic Math Dates & Calenders
In this chapter we shall study certain characteristics of dates and the corresponding days on which they fall. We will also discuss a technique which will help you find the day on which any date falls or the entire century!
Vedic Math Day Prediction Technique
Let us understand the technique to find the day on which any date falls for a single year. This technique will work for any one year only.
Single Year Calendar
Let us assume that we are dealing with the year 2004.
Given below is a key on the basis of which you will be able to tell me the day on which any date falls for the year 2004.
417 426 415 375
There are twelve numbers. Each number represents a month of the year. The number '4' represent January, the next number '1' represent February, the next number '7' represent March and so on up to the last number '5' which represent December.
Basically, each of these number represents the first Sunday of its corresponding month.
Hence, 4 January is a Sunday ; 1 February is a Sunday ; 7 March is a Sunday and so on...
On the basis of the above information, you will be able to predict the day for any given date.
What day is 6th January?
According to the key, 4th January is a Sunday. Hence, 6th January is a Tuesday
What is the day on 4th August?
Since August is the eighth month of the year, we use the eight digit in the key. The eight digit that represent August is 1. We know that it represent the first Sunday of August. Since 1st August is a Sunday and so 4th August is a Wednesday.
On which day does Christmas fall in the year 2004?
The number 5 represents December. We know 5th December is a Sunday. Adding 7, we get 12th as the next Sunday, then 19th & 26th as the next Sundays. So December 25th is a Saturday. Thus Christmas falls on a Saturday in the year 2004.
What day is 23rd March?
The third number in the key, which represents March, is 7. So, 7 is a Sunday. The next Sundays are 14th and 21st March. Since we know that 21st March is a Sunday and therefore 23rd March is a Tuesday.
This keys will work only for the year 2004. Since the first Sundays of every month keep on changing, we will have a different key for every year. The Key for the next few years is as given below.
Vedic Math Date Prediction Technique
Now let us study a system of finding the day on which any date falls for the entire century. After studying this technique, you shall be able to predict the day on which any day falls from 1st January 1901 to 31st December 2000.
Before proceeding with the technique, Let us note down keys of the months. This key will remain the same for any given year from 1901 to 2000
You have to memorize this months keys. To facilitate memorizing the key. We have made small verse. The verse will help you to memorize the key easily.
It's the square of twelve = 144
and the square of five = 025
and the square of six = 036
and one-four-six = 146
In this method of calculation, the final answer is obtained in the form of remainder. On the basis of this remainder we are able to predict the day of the week.

The days key is very simple and needs no learning. Next, we will do an overview of the steps used in predicting the day.
Take the last two digits of the year (If the year is 1953 then take 53)
Add the number of leap years from 1901
Add the month key
Add the date
Divide the total by 7
Take the remainder and verify it with the day key
These are the six steps that are required to predict the day. Note that the second step requires us to calculate the number of leap years from 1901. A year is a leap year if the last two digits are divisible by '4'. Hence, the years 1904, 1908, 1912, 1916, 1920, etc are all leap years.
