Here is a handy trick to calculate last day of any month.
Assuming y and m contain the year & month for which you want to find the last day’s date, write
=DATE(y, m+1,0)
That is right, you can use ZERO (0) as the day.
When you do this, Excel tells us the last day of previous month.
How to calculate last day if I have a date in that month:
Instead of year and month, if you know a date & you want to find what is the last date… then use:
=EOMONTH(date, 0)
How to calculate the last working day of a month?
If you just care about working days.. then use:
=WORKDAY(DATE(y,m+1,1), -1)
This will give us the last working day of a month.
Dealing with holidays:
Very simple. Pass on a list of holidays to WORKDAY as last parameter. Like this:
=WORKDAY(DATE(y,m+1,1), -1, F1:F20)
This assumes, F1:F20 has a list of holiday dates.
Dealing with different weekend types:
Not everyone observes Saturday & Sunday as weekend. For example, I do not work on Tuesdays. You might have Sunday thru Thursday work week. If so,
use WORKDAY.INTL function, like this:
=WORKDAY.INTL(DATE(y,m+1,1), -1, 7)
Weekend type 7 is for Friday & Saturday weekend.

You are right, Chandoo. I was playing with the colour numbers last week and some of them don't appear different from each other. Others are totally different from yours.
@Duncan
Each version of Excel, post 2003, renders colors slightly differently
Different language versions may also have different default color palettes
Hello in french
excel 2010
colo1 = couleur1 = black
[couleur1]; [couleur2]; etc..
@Hui, thank you very much again for this great post.
However - under Excel 2007, Hungarian version your solution does not work with color names. I've tried both English and Hungarian names, but drops an error message "not valid formats"
Do you have any idea how to solve this issue?
thanks in advance
@Andras
Without a Hungarian version of Excel 2003 I don't think I can assist
Have you tried using the colour numbers? I couldn't get the names to work (despite using an english version of excel). but it did work with the numbers though. I left out the "u" and was easily able to produce burgundy using [color9]
Here a possible solution: find an English version of Excel, write there the formats using English names, then open the file in the Hungarian version and see the translation.
In Excel 2007 I can't get the colour names to work e.g Sea Green but the numbers do e.g color3 - colour3 does not work so I must bow to the country that has stolen my language (ha ha!)
Hey chandoo, nice Tip!
Wouldn't be easier just apply some conditional formatting for negative numbers and another for positive numbers? Or there's some cases that you can't do that?
Unfortunately the TEXT function doesn't color the cell as number formatting does.
Hi Hui,
Great post Sir, love the new way of formatting with color numbers.
I am using 2007, and it leads me to the last color number 56.
Thanks Hui.

Thanks Hui - works a treat!
Thank you, very helpful.
Trying to figure out if it is possible to apply color only to a part of the cell?
E.g. I have a value formatted as Accounting with a currency symbol.
Those I find somewhat distracting though necessary. If I could make them less obtrusive by coloring them gray while the number would stay black, that would be great. Tried tinkering with the format string, but didn't get the desired result. Single color for complete cell value works, but coloring just part of it could not be achieved. Maybe somebody managed that?
Exactly what I was looking for - thank you!
colour in the Australian doesn't work - we have to go American and no problem.
I always thought is was 56 colours notice you have 57. Cool.
thanks
