What day of the week will July 4th, 2050 fall on, and do you have an
explanation of how you figured this out? (ie No single word answers, I
need an explanation)

Hi there,

MONDAY!

There are several methods for calculating the day of the week for a
particular date. If the method is a shortcut, it will be quicker and
easier to use, yet how it works will be less obvious. For example, a
computer program is the easiest to use, yet the hardest to understand
how it works. At the other end of the scale, you could scribble down
hundreds of calendar pages until you reached 2050, which would be
laborious, but very easy to understand.

The middle ground is a formula like this one:

1. Take the last 2 digits of the year and add a quarter onto itself.
(04 + 1 = 5)
2. Get the corresponding code for the month. (see link below)
3. Take the day. (=13) 
4. Add the numbers together (5 + 5 + 13 = 23) 
5. Take away 7 (or multiples of 7) until a number from 1-7 is left.
(23 - 21 =2)
6. This number corresponds to the day of the week. (1 = Monday, 2 =
Tuesday, etc.) In this case 2 = Tuesday

To see the codes for each month, plus other rules which apply to this
formula, see this site:

They also link to some other ways of doing it.

The Answer
==========

1. 50 + 12 = 62
2. The code for July is 5
3. The day is 4
4. Add them together (62+5+4=71)
5. Subtract multiples of 7 (71-70=1)
6. 1 = Monday

I verified this by using the Flash program on the above site.

Thanks for the quick and good answer!

He beat me to it.

I was just going to explain that you can double-click on the ol' clock
down there, change the date to July 4, 2050, and go "oh look, it's a
monday". :)

He beat me too.  Monday is confirmed.

A spreadsheet program can calculate it quite easily.

On Lotus 123, the formula is @DATEINFO(@DATE(2050,7,4),2)
