Here is a cool count-down timer application made in VBA to remind you about our VBAClasses registration closing time!

I know it is blindingly awesome. So I will give you a few seconds before reading further.
….
Back already? Great.
I was thinking of ways to tell you that you have got less than 3 days to join our VBA Class. Then it struck me, why not make an Excel workbook to tell you how much time you have got? So I did just that.
Here is a video demo of how the VBA application works (watch on YouTube):
Download the VBA Classes Count-down Timer Workbook:
Click here to download the workbook. Please enable macros to see it.
PS: You must drag and drop this file in to Excel 2007 or above to see it.
How does the Count-down Timer Work?
First, I must tell you about its limitations:
- This workbook assumes that your computer is located at the hotspot (or city) you have chosen.
- The current time is fetched from your computer’s local time using NOW() formula.
Now, the basic construction of this workbook can be broken down to 3 parts:
- Hotspot / City Selection
- Countdown Timer
- Formatting
Hotspot / City Selection:
- I took an outline map of world and put it in an empty sheet. On top of this I have added 9 hotspots by drawing nine circles.
- I have named these hotspots spot1, spot2…,spot9
- As you can guess, each of these spots correspond to one time zone, from PST to Australian Time.
- I have assigned macros to each of them. The macros would just modify a cell named valSpot with the name of the spot on which I clicked.
- Based on the clicked spot, I fetched the corresponding closing time from a table like this:

- Then, I calculated the time left by subtracting current time from closing time.
- A similar logic is used for City selection.
Countdown timer:
- I have inserted a check box and linked it to a cell named showTimer
- I have also assigned a macro startTimer to the checkbox.
- The startTimer macro would call a different macro named – countDownTime()
- In this, I wrote a while loop that would check if the showTimer is true and ask Excel to update the currentTime once every second
- The code can be examined from the downloaded file.
Formatting:
I am leaving this to your imagination.
Bottom line: Join our VBA Classes
Of course, the whole point of this is very simple.
If you want to learn VBA, then please join our VBA classes. We will be closing registrations in 3 more days. After that we will be busy for next few months teaching VBA to those of you who joined us.

PS: When you join our VBA Class, you get to learn how this timer app is constructed in a detailed 40 minute lesson. That is just one of the many lessons in our class. So, join us already.

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
