1.) I simply pre-memorized all 366 possible dates as a value from -3 to 3. 2.) Then I just add that to one of the 4 possible century codes of 2,0,-2, or 3 (7 possible century codes for Julian from -3 to 3) and finally, 3.) Add that to a pre-memorized value for each of the 100 years from 00 to 99. For example, my birthdate of March 19, 1982 goes: -2+3-3=-2 so Friday! Or shortcutting, I just cancel the 3 and -3, and -2 is Friday! The fastest way to do this is to pre-memorize all 100 year values from 00 to 99. Then I just add that to the century code and finally add that to a pre-memorized value for each of the possible 366 dates (these 3 values can be added together in any order you like). For example, June 15, 2012 would simply be: 2+2+1=5, so Friday! June 15 always has a value of 2 (pre-memorized) 2000's has a century code of 2 and, year 12 always has a value of 1 (pre-memorized) 2+2+1=5, Friday! Anytime leapyear happens just subtract one from the answer for January or February only, all other months stay the same! I calculate any day of the week using my method in less than a second, almost instantly to 2 seconds tops if I'm thinking a bit. I do both the Julian and Gregorian calendars in both AD and BC infinitely into the past or the future.I do other cool tricks that aren't heard of very often, for example since this calendar math can be viewed as just a simple addition problem, we can also solve for a missing value using subtraction! For example, if we already know the day of the week to be Friday for example, we can solve for a possible month/months or even a date from 1 to 31 or even a possible year or century. Example: Which month or months did Friday the 13th fall on in 1899? 1899 was a Tuesday year (-2+4=2) or (5-3=2). So, Tuesday was the 10th since 3 days later was Friday the 13th. So, 2+13+x=5 (Friday) x=4 because 15+(-10)=5 -10+14=4 Mod7 arithmetic Only January and October had a month code of 4 😁. So it only happened twice that year, in January and in October. Also we can say more intuitively that since 1899 was a Tuesday year, and Friday being 3 days later, which month/months had the Doomsday of 3,10,17,24,31? and obviously that is only January and October. If the question changed to what were all of the Fridays in January and October for example in 1899? We can say "the 6th, 13th, 20th, and 27th" If someone were to instead ask for example on Friday the 13th from 1883 to 1900 what year/years did that happen? We can say "only in 1893 and 1899" In this situation we just needed to find the missing year code of (4 or -3) and only 93 and 99 have that year code in that date range. Likewise, we could have instead solved for the century 😉 also if already given a year.

Sure this works, but here's a simpler method that works for years 1900-2099. You only track one number throughout this method which makes it easy to do quickly in your head. The key is doing the mod 7 (remainder after dividing by 7), you can apply it any time to any number after step 2 through the calculation. 1) Subtract 1900 from the year. 2) multiply that number by 1.25 (add a quarter), round down, if its a leap year subtract 1. Reduce to mod 7. 3) walk through the completed months of the target year and add the mod 7 for that month (31 days=3, 30 days=2...). Reduce to mod 7. 4) add the target day of the month (or the mod 7 of it) and get the mod 7 for the sum. This is your day of the week (0=Sun, 1=Mon,.. 6=Sat). Here's an example for a date later this year, 2019-06-21. 1) 2019-1900 = 119 2) 119 + 29.75 = 148 (rounded down), 148 mod 7 = 1 3) 1 + 3 (Jan) + 3 (Mar) + 2 (Apr) + 3 (May) = 12, 12 mod 7 = 5 4) 5 + 21 = 26, 26 mod 7 = 5, Answer is 5 - Friday (if you prefer, 5 + (21 mod 7) or 5+0) For 1960-03-01 1) 60 2) 60 + 15 - 1 (leap year) = 4 (after mod 7) 3) 4 + 3 (Jan) + 1 (Feb) -> 1 (after mod 7) 4) 1 + 1 = 2 = Tuesday This method works because of 2 factors. Jan 1, 1900 is a Monday (day 1 on date 1), and in that year span there are leap years every 0.25 years so you can calculate your "odd days" with the multiply by 1.25 trick. The other advantage to this method is that it doesn't require any memorization other than the method itself and the number of days per month.

I had @Sunanda Alapati reply to my comment, but I can't see it anywhere other than my notification. The question was about January 1, 2099 coming up as a Thursday using my method and Sunday using the video method. The correct day of the week is Thursday, I get that with either method, I don't know why you are getting Sunday. For the video method, you have no odd days for the century, 122 odd days for the year (74 normal years, 24 leap years) and 1 more day for the 1st. That leaves a 4 as the remainder which is Thursday.
@yashrupani1608
@yashrupani1608 5 жыл бұрын
@Sunanda Alapati by the video method : 2099 2000 = 0 odd day 98 = 24x2(98/4*2odd days for leap year) + 74(1odd day for normal year)= 48+74 = 122 @ 122/7 odd day = 3odd days . Jan 1 = 1odd day .. i.e; 3odd day + 1odd day = 4odd day = Thursday ---- SOLUTION BY VIDEO METHOD

Odd days denote the number of days after completing any number of week cycles. We could say that *A week starts on Monday and ends on Sunday by this concept.* When you say year 2000 has 0 odd days it means by the end of the year, an exact number of week cycles has been completed. Which tells us that December 31 is a Sunday. A new week starts on 1 Jan 2001 (1odd day= Monday.) By the next day there would be 2 odd days which means it's the second day of a new week therefore Tuesday and so on.

When i watched this vdo immediately i subscribed your channel. Then i wanted to know whether you are still making vdo s or not. So i went through your channel and saw your recent posts. It made me very happy because the world needs the teacher like you. I’m highly impressed by the way you make clear the concept. You are a real and true teacher. Please continue teaching online. The learners from abroad too can benefit from you.Thank you and best of Luck.

It is easier for students to understand that for century years to be leap years the number of centuries should be divisible by 4.Eg. Look at 1700, 1800, 1900, 2000. At a glance one can see that only 20 is divisible by 4.

Dhiraj ,, let’s us understand that the month is given till Nov which is incomplete year of 2020. For the calculations we have to take complete year ie2019 as per rule 2019 2000 + 19 /4 ( 4 leap year and 15 ordinary years 0+(4x2+15x1)+3+1(lepyears)+3+2+3+2+3+3+2+3+ (***1) 8+15+26= 49/7 = O odd day ie Sunday Follow my method times less consume to be honest Sir method is quit complicated (***) given date may be 15,17,25,35etc whatever may be always divided by 7( applicable when it’s (= or greater than 7) and put the remainder in that month..

Basically, this is what you do: Take the last two digits of the year. Divide by 4, discarding any fraction. Add the day of the month. Add the month's key value: JFM AMJ JAS OND 144 025 036 146 Subtract 1 for January or February of a leap year. For a Gregorian date, add 0 for 1900's, 6 for 2000's, 4 for 1700's, 2 for 1800's; for other years, add or subtract multiples of 400. For a Julian date, add 1 for 1700's, and 1 for every additional century you go back. Add the last two digits of the year. Divide by 7 and take the remainder
