Because there are 36524 days in a hundred years and if you divide it into 7, you will get the answer of 5217 weeks and 5 days extra.

why "Take 5 days from each century that’s 5 from 17, 5 from 18 and 5

from 19" when the date is 11/11/1991?

1.

Take 5 days from each century that’s 5 from 17, 5 from 18 and 5 from 19.

2.

Take 90 days from year 1901 to year 1990.

3.

Take 22 days as leap years because from year 19901 to year 1990, there

are 22 leap years.

4.

Take 3 days each from January, March, May, July,  August and October.

5.

Take 2 days each from April, June and September.

6.

Take 11 days from November.

7.

The final calculation will be:

5+5+5+90+22+3+3+2+3+2+3+3+2+3+11=162 Divide into 7=23 remainder 1.

8.

Now count it as Sunday 0 Monday 1.

November 11 1991 was Monday.

Hope that make sense!

Yes dear, you misunderstood the calculation.

1.

Take 19 days from year 2001 to year 2019.

2.

Take 4 days because from year 2001 to year 2019, there are 4 leap years.

3.

Take 3 days each  from January, March, May that will be 9 days.

4.

Take 2 days each from April and June that will be 4.

5.

Take 1 from February because the year 2020 will be leap year.

6.

Take 8 days from July.

7.

The total will be 45 not 36.

The final calculation will be:

19+4+3+1+3+2+3+2+8=45 divide into 7 iquals 6 remainder 3.

So counting will Sunday 0, Monday 1, Tuesday 2, and Wednessday 3.

So July 8th 2020 will be Wednessday!

date is 7/8/2020

4 leap years within those 19 years. so add a 4.

starting from January 2020:

January, March and May have 31 days. so add a 3.

April and June have 30 days. so add a 2.

add the 8 days of July.

total is 36 divided by 7 (days in a week?) = 5.142 = 5.1.

so 7/8/2020 is a Monday. but it's not. where did I go wrong, or is

something missing?

Hello Mario,

As far as step 1 and why you use 17, You just use one number less than

the last 2 digits of the year.  So since that was 18, you would use the

number 17.  So if you were looking at a date with the year 2020, then

you would use 19.  Again, one less than the last 2 digits of the year.

Now, as far as step 3, you basically add 3 for each month that has 31

days, 2 for each month that has 30 days, and 1 for February if it has 29

days.

Now you only count the months up to the month with the date you are

looking for.  For example, if your date is in May, then you would do

this for January through April.  If your date is in October, then you

would do this for January through September.

And finally, you would add the days in the month up to the date you are

looking for.  For example, if your date is the 13th of the month, then

Now step 4 is just the result from adding the numbers from step 3.  Step

3 was the instructions, and step 4 is the calculation of step 3.

Step 5 is just doing the final calculation.  The important part of the

calculation is the remainder.  In the example given, the remainder was

2, so that is what determined the day of the week.

For all calculations, if your remainder is 0 then your day is Sunday, 1

then Monday, 2 then Tuesday, and so on.

clearly explain it to me step by step because I don't follow how it's

done. yes, it is written, but I just don't understand like in step 1,

why do you arrive at using 17 and not 18? is it because 2018 is not an

odd year? and for step 3 and 4, I am lost.

Suppose, you don’t have anything computer, cell phone or any kind of

calendar, are you not able to tell the day of the week of any date?

Let me tell you how you can do it!

1.

Take 17 that is 17 years of 21st century.

2.

Take 4 meaning that from year 1 to year 17, there  are 4 leap years.

3.

Take 3 from the months which have 31 days, 2 from the months which have

30 days and take 1 from the month which have 29 days.

4.

From that calculations, there are 6 months having 31 days meaning 18

days, 4 months having 30 days meaning 8 days and take 25 days from December.

5.

Now final calculation is:

17+4+18+8+25=72 divided by 7=10 remaining 2.

6.

Now you can count them as, Sunday 0 Monday 1 and Tuesday 2.

So December 25 2018 will be Tuesday!

Actually, if you want to know what day a particular date is, just type

the date in a cell, e.g. in A1 type 12/24/2018, then press Control+1 to

format the cell and select the date format, then from the available

options select the one that has the weekday included (for me it’s the

second from the top).

If, for example, I enter 12/25/2018 into A1 and then apply that format,

it will read “Tuesday, December 25, 2018” so I now know that Christmas

day this year is on a Tuesday.

Now, if I want to know how many days it is until Christmas from today

(May 11), I type 5/11/2018 into cell A2, then in cell A3 I subtract the

larger date (Christmas) from the smaller date (today), so I put =A1-A2

and the result in this case will be 228 which is the correct number of

days from May 11 until December 25.

the day

Hi,

Following is a formula to calculate the day of the week  from an input date.

In the first cell, in this case A4, type in 3/12/1988 and the cell with

the formula will display the week day.

=TEXT(A4,"dddd")

Depending on where you live and the date format, you may need to change

the formula a little.  This formula  works on 3 December 1988 and not

December 12 format.  But then it may not need to be altered at all.

You’ll just need to experiment.

Subject: Where can I learn about formulas for Excel?

Hi.

I’m looking for a source to learn about the different formulas for

Excel.  I purchased the book that CathyAnne Murtha wrote, but it doesn’t

contain all the formulas that I’m looking for.  Essentially, I’d like a

kind of Excel for Dummies where all the formulas are listed and how they

work.  As an example, I’d like to know how to have Excel tell me the day

of the week a date will be.  Also, I’d like to know how many days are

between dates.  I looked through the book I got from Ms. Murtha, but it

doesn’t list all the formulas.

Thanks for any help.  Dates aren’t the only thing I’m looking for.  I

know Excel is a very powerful program, and I’d like to learn how to use

it to its fullest potential.

Thanks for any info.

Have a blessed day and don’t work too hard.
