Hi and welcome to my website. Here you can find out how to add week numbers to Google Calendar. I have made a custom calendar which adds small week number icons to the title bar of the first day of every week. You can see an image of how it looks below. You can add these week numbers to your own calendar with the press of a button.
Note: Google have recently made their own week numbers, so you might want to check that out. There are instructions on how to add their calendar a little further down on this page.
To add my week numbers, simply use this box:
Here is an image showing how it will look when you have added the calendar.
Pretty neat, right? I hope these week numbers will make your life easier. I have hosted this calendar since 2006 and it currently contains week numbers throughout 2015.
You can remove the week numbers just as you would any other calendar. Simply go to your settings and press "Unsubscribe". If you just want to turn them off for a while, you can simply press the calendar called "Week Numbers" in your calendar list and the week numbers will disappear until you press it again.
Google have finally gotten their act together and have added a pretty easy way to add official week numbers, if you know where to look. You have to go to a place called "Interesting Calendars." To get there, press the dropdown button () in the box called "Other calendars", then press "Browse Interesting Calendars," then go to the tab called "More" and subscribe to the calendar called "Week Numbers." In my test it appears that it adds the same calendar regardless of what language you use, and the week numbers are always displayed on Mondays. Google's week numbers look like this: .
The rest of this page is about my week numbers.
Due to the fact that some countries number weeks a little differently, I encourage you to verify that my week numbers are correct in your country. Pick up a local calendar and make sure the week numbers match. Note that traditional paper calendars often make mistakes with week 53, where they usually label it as week 1. But if you look at the calendar for the next year, the error should be fixed.
Your mileage may vary. Don't bug me about it.

I can not help you customize the week numbers. All the information you will need to create your own calendar like this is on the bottom of this page and in Google's official documentation.
If the button on the top of the page didn't work, then you can try these links:
If you are still unable to add the week numbers, then you can try to add them from within Google Calendar. This also works in Google Apps. Just enter this text in the text field in the "Other calendar" box to the left in Google Calendar:
Google Apps users can make a direct link to add the week numbers to their domain. Simply edit these links to your domain name:
Just remember to replace example.com with your domain!
You might get the error message "The following are not Google Calendar users: firstname.lastname@example.org" when opening Google Calendar. It has only happened a few times, but each time it has resolved itself after a few days. I suspect this happens when Google's servers are having some troubles. There is nothing I can do about it, just sit tight and it will go away after a few days. You can also consider using Google's week numbers, described above.
One user sent me some instructions on how he or she worked around this error message:
