At work, I interact with Europeans on a daily basis. When building schedules they often refer to "Week Numbers". Before I found this calendar option in Outlook it was a little annoying however now, I’ve been converted….. I love it.
Below is a SIMPLE step by step for adding week numbers to your Outlook 2003 or Outlook 2007 calendar. Try it out. It’s GROOVY!
1: Click Tools, Options
2. On the Preferences tab, Click Calendar Options…
3. Check box "Show week numbers in the Month View and Date Navigator"
4. Click OK a few times and YOUR DONE!!! GROOVY!!!

I spent a lot of time looking for this option.
Welcome to the site Jelena!
It’s excellent to see we were able to help.
On Outlook 2003, there is a bug as January 1st 2008 up to January 6th 2008 is considered as Week 53 by Microsoft.
How can I solve this issue?
Thanks

@Alnoor - Welcome to the site!
That’s very odd. I’m looking at one of my machines running Microsoft Outlook 2003 and I don’t have a week 53. Week 1 starts as normal (12/30/07 - 01/05/08). Please start a thread in the FORUM and explain how your calendar is setup, specifically: What timezone are you in? What does did you set the Week to begin? What OS? Etc…
fantastic, excellent
@Stormin - Welcome to the site and Thank you for the feedback!
I have Outlook 2003. When I go to Calendar Options, I only have the option to show week numbers in the Date Navigator. The text doesn’t match what you have in the screen shot. Is there some place is the system registry that I could go to enable the option to show it in the Month View as well?
@Goddammit - The screenshot was taken from Outlook 2007 so you are correct, your options WILL look a little different in Outlook 2003.
Additionally, Outlook 2003 does not support the Week number in the Month view. Only Outlook 2007 does this hence the difference in the “Check” box Language. If you enable the Check box in Outlook 2003 however, you will have the week numbers in the date navigator (the little calendar on the left side of your calendar views) as shown in the screenshots at the END of my article.
Sorry for the confusion. When I get a chance I’ll update the article to reflect this information.
BTW - Welcome to the site! Nice name btw…
This is very useful.
However, I work in a University and week 1 is the 1st September, and I would like to display these week numbers
Any suggestions?? I use outlook 2007

@Big Rich - Welcome to the site!
You ask an interesting question. I did some quick searching and what I’ve found “so far” is that Microsoft doesn’t support changing when in the year Week 1 Starts. Take a look here: http://support.microsoft.com/kb/196567
I keep digging but it doesn’t look very promising. Perhaps one of our readers has move info?
Thanks!
Wish iCal could do the same..
Thank you very much! It simplified my work and cease the confusions of work schedules.
Thanks for the very clear how to.
Thank you so much. Such a simple thing. Go figure. Appreciate the help.
I’ve been looking for this option in the Outlook help forever. This is a lifesaver for me as otherwise I’ve to always refer to my desk calendar.
