Dear,  the total is right but you forgot to mention number 18 which is the calculation of January, March, May, July, August and October.

Now divide the total into 7 and count the remainder that is 5.

Sunday 0, Monday 1, Tuesday 2, Wednessday 3, Thursday 4 and Friday 5.

November 23 2018 will be Friday.

There is no number 7 because we count Sunday as 0 and there are 7 days in a week!

I must be some thing wrong.  Take November 23, 2018.

The formula I come up with is:  17+4+6+23=68, 68/7=9.7.  If Sunday is 0 and Monday is 1 where is 7?

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 you would add 13, if your date is the 25th, then you would add 25.

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.
