## Math For Spacing Out Three-Day Weekends, But Accounting for Holidays

I'm a big honkin' geek, and I would like to figure out an Excel formula I could reuse from year to year to space out my vacation day choices -- but including holidays, which would prevent even distribution. How can I still get as close as possible? More inside. [more inside]

## Excel 2013 - Using data from two columns to identify a row in a third

I have data on one sheet of an Excel document with three columns. I want to extract this for use on another sheet as follows: If a row in Column A contains X (text string) and a row in column B contains Y (also a text string) then what does the row in column C (always a value) which matches these two criteria contain? With the data I have, this will always return a single result. [more inside]

## Excel formula: Letter to Number (and vice versa)

I'm working on a formula (not a macro) to convert a Letter (in this case, a column letter) to a Number, and vice versa.
So: A = 1, B = 2, C = 3, Z = 26, AA = 27, AB = 28, AC = 29, ZZ = 702, AAA = 703, AAB = 704, AAC = 705, BAA = 1379, etc...
Of my three part formula(s), I have the one-letter and two-letter columns working, but I run into issues with the three-letter columns (AAA and beyond). [more inside]

## I need to be able to memorize several formulas for a test next week

I'm taking a numerical methods class and there are all these discretization schemes of partial differential equations named after pairs of dudes and they all are kinda the same, maybe a bit different in indexes....
I'm trying to organize it all in my head, like a frat house, with the dudes that worked on the same scheme being roommates, but it seems to be taking a long time to actually "find" a place for each scheme in their "rooms" and keeping it there in a sort of visual arrangement.
Test is no books no notes, and everything kinda of just jumbles inside my head right now.

## Foolproof way to feed baby kittens?

I've got three new baby kittens with no mother, and I need to feed them. I don't have access to any good pet stores or veterinary clinics, but I do have lactose-free baby formula and a plastic syringe with the needle removed, which I've been using to feed them so far. But is there a foolproof method of holding them or something to get them to drink from it? I can usually get them to drink, but only about half of the amount recommended. More details inside.

## YTD total based on sum of last number in another row that has a value?

YTD total based on sum of last number in another row that has a value?
I need to sum up the values in one row based on the matching row below it. For example, if I have a target of $1000 a month, and I only have actual revenue numbers through June, I would like to calculate the year to date for the target from Jan to June. Once July numbers are put in, I'd want the YTD for the target to update to Jan to Jul.
I have tried a couple of variations on COUNT, INDEX and OFFSET.
Example is here: http://malcommc.com/ytd.xls
