What day of the week was 23. What day of the week was your birthday? Significance and magical abilities

There are many ways to pump the brain. N-back tasks or mobile apps to practice fast mental counting. But these tasks are divorced from the current reality, but I would like to pump the brain with a practical skill.

What for? After all, you can quickly calculate on the gadget. Alas, not at all fast, because. it will take time to search for and activate the gadget, search for the application, enter the date, and understand the result. And you can also please your friends / girlfriends with your suddenly appeared extraordinary abilities. By the way, friends will quickly realize the convenience of using a perpetual calendar with a voice interface.

Is it possible? Once upon a time, we managed without computers. One of the "talent-hunting" TV shows showed a trained three-year-old who can calculate the product of three-digit numbers (save your kids). However, adults are no longer children and their brains are partially crystallized, in the sense that we are poorly trained. So you need to memorize as little as possible and use the available skills as much as possible.

In algorithmics, often the amount of computation can be compensated by the amount of memory. Those. the more RAM available, the less computation required. The brain works similarly - the more we remember, the faster we look for a solution. We remembered a few formulas for solving the Rubik's Cube - you will collect it in a couple of minutes (after a long workout). Remembered one and a half hundred formulas - you will collect them in a couple of tens of seconds. World record 2013 - 8.18 sec. Once again: the more we remember, the faster the solution.

Algorithm

You need to take the offset (day of the week) of the first day of the year (y) and the offset of the month (m). Then calculate the sum y + m + d, where d is the day of the month, and find the remainder after dividing by 7. We get the number of the day of the week.

What to remember

Reflections

In general, it is enough to remember all the days of the week for all 28 years (the periodicity is proportional to the product of the periods of leap years and the days of the week). Sequence in 10k. That's quite a lot.

If you add one addition operation, then it will be enough to remember only a couple of rows of numbers:

M(month) = ( 6 2 2 5 0 3 5 1 4 6 2 4 ), from January to December

Y(year) = ( 6 0 1 2 4 5 6 0 2 3 4 5 0 1 2 3 5 6 0 1 3 4 5 6 1 2 3 4 ), from 1988 to 2015

The offsets for the month are taken from the calendar of some year. The month offset is equal to the number of gray squares at the beginning of the month. For example, the non-leap year 2006. The offset for this year will be 0.

Still, remembering the offsets for all the years and then doing a quick index lookup is quite a cognitive task. There is an alternative way - to calculate. You need to take the last two digits of the year (+100 for the XXI century) - Y. Next, find the nearest past leap year Yv. Take dY \u003d Y - Yv. Then the year offset can be calculated

Y(Y) = (50 – Yv/2 + dY)

The disadvantage of the formula is that for 2004 and later the offset will be negative, and for the beginning and middle of the 20th century it will be two-digit, which slightly complicates mental calculations. It is possible to use different formulas for each century, which take into account only the two lower digits of the year. For example, 12 for 2012 and 1912.

XX: (50 - Yv/2 + dY) % 7 or (8 - Yv/2% 7 + dY)
XXI: (7 - Yv / 2% 7 + dY)

As a result, it may be easier to remember the offset table in this form:

The offset for a year can be calculated as the sum of the offset of the next smaller leap year and its difference from the desired year. Seven digits are easier to remember than 28. In addition, the numbers are in descending order with a step of 2. (Yes, yes, (0 - 2) will be 5, remember the remainder of division by 7). You can remember the numbers (6, 4, 2, 0, -2, -4, -6), which will give a similar result when calculating. Years divisible by 20 are located in an oblique 3x3 square according to the "knight's move" scheme with the year 2000 in the center. The values ​​of the offsets of months and years are coordinated so that the offset of 0 falls on the year 2000. And the step between adjacent rows is 28 years.

For example, for 2014 the offset would be y(2014) = y(2012) + 2 = 1 + 2 = 3. And the day of the programmer on September 13, 2014 would be (y(2014) + m(Sep) + 13) = (3 + 4 + 13) = 20 => 20% 7 = 6, i.e. Saturday.

We structure a series of offsets for months. It is convenient to memorize the values ​​according to the seasons: spring, summer, autumn, winter.

Notice that suddenly (?), in order from top to bottom and left to right, the numbers lined up in an ascending row (first color table). You can remember only the remainders of division by 7 (second color table) or to restore the entire table, remember only the differences (last table). Adding 1 to 1, we get 2 for March, 2+1=3 for June, 3+1=4 for September, and so on. Identical values ​​are painted in the same colors. For a quick search, the second color table will help us. Remember that the lines are the seasons, starting with spring. This is extremely unusual. But in ancient Rome, the year began with March. This is reflected in the names of the months in Latin numerals: September ber/ Octo ber/ Novem ber/ Decem ber - 7/8/9/10, i.e. February was the last 12th month of the year to which a leap day was added.

Important!!! Programmers have an eternal problem with the lost unit. In our problem, this was not possible without it. For January and February of a leap year, subtract one.

February 14, 2012 = (y(2012)+m(Feb)+14) - 1 = (1 + 2 +14) - 1 => 16% 7 = 2, i.e. Tuesday.

You also need to remember that not all years that are divisible by 4 will be leap years (exceptions are 2100, 1900, 1800, ....). Accordingly, it is necessary to take into account the offset for the eyelid. However, even if you do not take into account the last exception, you can accurately operate with the days of the week for the 20th and 21st centuries, which is sufficient for most everyday cases.

A bit of optimization.

Calculations can be performed in streaming mode. Usually, the date of birth (or any other date) is reported starting from the day of the month, for example, December 23, 1913. Those. in the process of reporting the date, you can partially calculate the desired amount 23 + m(Dec) = 27 or even 23% 7 + m(Dec) = 2 + 4 = 6 and then think y(1913) = y(1912) + 1 = 3 As a result, report 30% 7 = (6 + 3)% 7 = 2, Tuesday.

Often you have to operate with the dates of the current year. Those. you will always remember the offset of the year, because from frequent use, the value will be cached. For example, for 2014 the offset is 3.

What we got. The rules for filling out the tables are simple and you most likely remember them and can reproduce the cheat sheet for yourself anywhere at any time. But for quick counting, tables are easier to memorize in their entirety. After all, we do not restore the addition and multiplication tables for calculating change in front of the cash register. These tables are "stitched" in elementary school. The easiest way to memorize tables is to use the Week Brain Calc simulator (Windows Phone).

After a short workout, you can please your loved ones with your unique abilities.

To determine the day of the week for any date without the help of a calendar, it is not necessary to be a genius or clairvoyant. It is enough to remember a couple of formulas.

To determine the day of the week by date, you need to use the formula:

day of the week = (day + month code + year code) % 7

Explanations

Month code

The month and year codes are perhaps the hardest part of the formula.

You just need to remember the month code.

• 1 - January, October;
• 2 - May;
• 3 - August;
• 4 - February, March, November;
• 5 - June;
• 6 - December, September;
• 0 - April, July.

To remember such illogical data, the easiest way is to resort to associations.

Year code

The code of the year in the XXI century is calculated by the formula:

year code = (6 + last two digits of the year + last two digits of the year / 4) % 7

The "/" operator means the incomplete quotient, that is, the integer part of the division result.

• 2015: (6 + 15 + 15 / 4) % 7 = (6 + 15 + 3) % 7 = 25% 7 = 4;
• 2016: (6 + 16 + 16 / 4) % 7 = (6 + 16 + 4) % 7 = 26% 7 = 5;
• 2017: (6 + 17 + 17 / 4) % 7 = (6 + 17 + 4) % 7 = 27% 7 = 6;
• 2026: (6 + 26 + 26 / 4) % 7 = (6 + 26 + 6) % 7 = 38% 7 = 3.

If you want to know the day of the week for a date from another century, you will also have to take into account the values ​​of the century (6, 4, 2, 0). Instead of 6 for the next centuries there will be the following values:

• 16xx: 6;
• 17xx: 4;
• 18xx: 2;
• 19xx: 0;
• 20xx: 6;
• 21xx: 4 and so on.

It's simple here: % is the remainder operator when dividing.

Result interpretation

The start of the countdown is the weekend, that is: 0 is Saturday, 1 is Sunday, and so on.

Calculation examples

• July 25, 2016: (25 + 0 + 5) % 7 = 30% 7 = 2 - Monday;
• August 8, 2017: (8 + 3 + 6) % 7 = 17% 7 = 3 - Tuesday;
• January 5, 2127:
  • (4 + 27 + 27 / 4) % 7 = (4 + 27 + 3) % 7 = 34% 7 = 6 - year code;
  • (5 + 1 + 6) % 7 = 10 % 7 = 5 - Thursday.

Of course, calculating the day of the week from a date in your head is not a vital skill in the age of technology. But this is a non-trivial exercise for everyone who likes to develop their memory and perform operations with numbers.

UPD. Unfortunately, this formula does not work correctly for a leap year. Until February 29 inclusive, you will have to add another unit to the formula to get the right day. Thanks to the readers for finding the error.

The inhabitants of the East attach great importance to the day of the week when a person was born. Thais are sure that he determines character and destiny. The Thai legend of the twelve sages says that the colors of the days of the week correspond to the colors of the thewada spirits in order to ward off bad weather and clear the way for a person to these angels. Every day has its "happy" and "unlucky" sides of the world.

Their house is always warm and cozy, they have many friends and acquaintances. However, it is difficult for them to find a soul mate, since Friday people cannot live within four walls - they need freedom, which not every lover will like, so it is better for jealous people to immediately refuse marriage to Friday persons.

Magic abilities. The scent for profit is well developed, so these people never live in poverty. They always have money and a stable income.

Saturday.

Those born on Saturday are ruled by Saturn, so they can endure a lot. These people are hardworking and smart, they are leisurely, but thorough. They do not like to lead, therefore they do not strive for career growth, they are closer to home comfort. But in the family they are often unhappy, because they believe that marriage is forever, which means that there is no need to take the initiative in maintaining the fire of feelings.

Sunday.

People born on Sunday are patronized by the Sun, so they are always comfortable in life. They are active and quite successful, although they cannot be called minions of fate, since quite often serious problems occur with them. The reason for them is the carelessness of Sunday people - they are lazy and optional. There are few family members among them, because they are too lazy to start a family in order to take care of someone. They usually go with the flow, which often brings them to the right and profitable place. These people need to learn hard work and assertiveness. A close person with such traits as prudence and authority helps them achieve a lot in life.

Magic abilities. Luck and the ability to guess lottery numbers, which they often use.

According to astrologers, our character is determined not only by the date and time of birth, but also by the day of the week on which we were born. Only few relatives can remember this information.

You can fill this gap with the help of an online calculator. To do this, it is enough to correctly fill in the appropriate fields. The day and month are given as two digits, and the year as four digits.

For example, you need to determine the day of the week of birth of a person who was born on March 8, 1980. In the field "day" we indicate - 08, in the field "month" - 03, "year" - 1980.

If the date consists of two-digit numbers, you do not need to add the number "zero" - the calculator will calculate everything correctly. For example, the date of birth is October 25, 1999. In the first field we indicate the number - 25, in the second - 10, in the third - 1999.

As a result, you will find out when a person was born and how it affected his character. So, people who were born on Monday have a good memory and intuition. With such qualities, they are unlikely to be pursued by bad luck, as one well-known song sings. But those who were born on Saturday are often inclined to pessimism and suspicion.

The calculator will help you calculate the day of the week for any date

The same calculator can be applied to any date. You can calculate what day of the week falls on January 1, December 31, May 9, March 8 (or other holidays) in any past or future year. This will allow you to more accurately restore the past or plan future events.
