first, for practical use, I have come across a very simple way to find the day of the week for any date of the current year. This idea is so easy, that most of you will wonder why you didn't think of it yourselves. This is it:—

All you have to do is memorize this twelve digit number:— 633752741631, the way you've been taught to do. You can break the digits down into your peg words and link them, or make up words to take in more than two digits at a time. For example, you can remember this number by making a link of these four words, chum, mug, linger and dishmat. Once you have memorized the number, you can tell the day of the week for any date of the year 1957! Each digit in the number represents the first Sunday of the month for one of the twelve months! The first Sunday in January falls on the 6th of January; the first Sunday in February falls on the 3rd of February; the first Sunday in March is the 3rd of March; April 7th is the first Sunday in April; May 5th is the first Sunday in May, and so on.

All right, so now you know the day of the month upon which the first Sunday falls for each month. How can this help you to know the day of the week for any date of the current year? Simple! You wish to know the day of the week for August 22nd, 1957—you know that the first Sunday of August is the 4th of the month. Knowing this, your calculations are elementary. If the 4th is a Sunday, then the next Sunday is the nth and the following Sunday, the 18th. The 18th is a Sunday, so the 19th is Monday, the 2oth is Tuesday, the 21st is Wednesday, and, of course, August 22nd is a Thursday!

Do you want to know the day of the week on which Christmas falls this year (1957)? Well, thanks to the twelve digit number, you know that the first Sunday of December is the 1st of the month. Therefore the 8th must be a Sunday, the 15th is a Sunday, and the 22nd is a Sunday. If the 22nd of December is a Sunday, then the 23rd is Monday, the 24th is Tuesday, and the 25th of December (Christmas) must fall on Wednesday this year!

Here is the way my mind actually works when I want the day of the week for any date this year:— I use the words, chum, mug, linger and dishmat to remember the twelve digits. I know that the word, "chum," gives me the first Sunday of the month for January and February. The word, "mug" tells me the first Sunday of March and April. "Linger" gives me the same information for May, June, July and August, and I know that "dishmat" represents September, October, November and December.

Now, if I wanted to know the day of the week for, say, November 9, 1957—I immediately think of "dishmat." I know that the third consonant sound of this word represents the first Sunday of November. The first Sunday is the 3rd, therefore the loth of November is also a Sunday; and, if the loth is a Sunday, the 9th of November must be a Saturday.

If, in your particular business, it would be a help if you knew the day of the week for the present year and the following year—get a hold of next year's calendar, and memorize the twelve digits for that year by making up a link of four or five words. You could do this for as many years as you want to, but I don't believe it's practical for more than two years. However, the memory feat that follows is also a practical method of knowing the day of the week for any date in the twentieth century.

As a stunt, you would tell your friends that you've memorized all the calendars of the twentieth century. To prove it, ask them to call out any date; a date of which they themselves know the day of the week. This is necessary, of course, so that they can check your answer. Most people remember the day of the week of their weddings, graduations or other important anniversaries. When the date is called, you almost immediately tell them the day of the week for that particular date!

To accomplish this you must know two things besides the month, day and year: a certain number for the year, which I will refer to as the "year key," and a certain number for the month, which I'll call the "month key."

Perhaps, if I explained the method and procedure before going into the technicalities, you would find it easier to understand. This is it:— Let's assume that you want to know the day of the week for March 27, 1913. Let's also assume that you know the "year key" for 1913 is 2, and that the "month key" for March is 4. You would add these two keys, arriving at #6. Now you add this number (6) to the day, in this particular case—#27 (March 27). This gives you a total of 33. The last step is to remove all the sevens from your total. Seven goes into 33 four times, (4X7== 28); remove 28 from 33, which gives you a final total of 5. That is your day—the fifth day of the week is Thursday! For this stunt we must consider Sunday as the first day, Monday the second day; Tuesday the third day; Wednesday the fourth day; Thursday the fifth day; Friday the sixth day and Saturday the seventh day.

March 27, 1913 did fall on a Thursday! Please don't consider this complicated; it isn't. Actually you will never have to add any numbers higher than seven. The keys for the years and the months are all either 0, 1, 2, 3, 4, 5, or 6. Sevens are always removed as soon as possible. If you had to add a "year key" of 5 to a "month key" of 6, you would arrive at 11; but immediately remove one seven, which leaves you with 4. The 4 is all you would have to keep working with. If the day that is given you is higher than seven, you remove all the sevens, i.e.—the date is the 16th; remove the two sevens (2X7= 14) and use the remainder of 2 only. In the above example, you would simply add 4 to

2, which tells you that the day of the week is the sixth, or Friday.

I will give you a few more actual examples, after I acquaint you with the year and month keys, and my methods for remembering them.

These are the month keys, which will always remain the same:—

January — 1 February — 4 March — 4 April — 0 May — 2 June — 5

July — 0 August — 3 September — 6 October — 1 November — 4 December — 6

I'll give you a memory aid for remembering each of these keys. The method that follows is one way, and I'll explain one other. You can use whichever you like best, or one which you think of yourself.

January is the first month of the year; therefore it is easy to recall that the key for January is 1.

February is a cold month, it usually has plenty of snow; both the words, "cold" and "snow" have four letters, so the key for February is 4.

In March the wind Wows. Both "wind" and "blow" have four letters; which will help you to remember that the key for March is 4.

April is known for its showers. "Showers" has seven letters; all the sevens must be removed; (7 — 7 = 0) so we know that the key for April is zero.

The key for May is 2. Do you recall the game we used to play when we were children, the one in which we would say, "May I take 2 giant steps?" Well, if you remember that phrase, you will recall that the key for May is 2. Or, you might think of "May Day" or "May Pole," consisting of two words.

"June Bride" is a common phrase; "bride" has five letters, so you will remember that the key for June is # 5.

For July, you could use this for a memory aid:— We all know that July 4th is a celebration of the signing of the Declaration of Independence in 1776. Take the two sevens from the year 1776, leaving 1 and 6. One and six are seven; remove this seven, leaving 0. Or, July 4th is usually associated with fire crackers; the word "cracker" has seven letters; remove the seven, leaving 0. The key for July is zero.

August is a hot month. The word "hot" has three letters; the key for August is 3.

September is the month during which the leaves start turning brown. "Leaves" has six letters; the key for September is 6.

Octo means eight, remove the seven (8 — 7=1) leaving one. The key for October is 1.

November is the election month. We vote in November; the word, "vote" has four letters, so the key for November is 4. Or, November is the nth month of the year, remove seven, leaving four.

Finally, the big holiday in December is Christmas. Christmas is the anniversary of the birth of Christ. "Christ" has six letters, so we know that 6 is the key for December.

Although some of the above may seem a bit far fetched, they will help you remember the keys. Another way would be to form a substitute word for each month, (the system of substitute words will be explained thoroughly in the following chapter) and associate that to the peg word that represents its key number. For zero, use any word that contains the s or z sound only; "zoo" is good, because it is easy to picture.

Here are some suggestions as to substitute words for all twelve months:—

January—Jan.—Abbreviation of "janitor." Associate janitor to "tie."

February—Fed.—Federal man. Fib or fob. Associate any of these to "rye."

March—See the object associated (rye) marching.

May—Use a person whose name is May, or picture a Maypole.

June—Picture a June Bride.

August—Gust of wind. Picture "ma" being blown about by a gust of wind.

September—Scepter or sipped.

October—Octopus or oboe.

November—Ember, new member.

December—Decimal, deceased or descend.

You can use either one of the two methods, or one that you come up with yourself.

Now we come to the year keys. I'll give you all the keys for the years 1900 to 1987. All the years that have 1 for a key, are listed together; the years with 2, are listed together, and so on.

I would suggest the use of another peg list to help you remember these keys. All you actually need is six words, representing the numbers 1 to 6, which will not conflict with your basic peg list. You can use any of the lists that I suggested in the previous chapter; the alphabet idea; ape, bean, sea, etc., or, pencil, swan, clover, table, star, yo-yo, etc. For zero, use "zoo" or "sue."

Since every year listed begins with 19, you don't have to try to remember that. Just associate the peg word for the last two digits of the year, to the word that you are using to represent the key numbers.

For instance, the key for 1941 is 2. Associate "rod" (41) to either "swan" or "bean," according to the list you're using. Make your associations for all of them. Go over them a few times, and before you know it, you'll have memorized
