I updated DOYV to be a Universal Binary. The interface is basically the same as before except I added a button (just below the window close button) to let the user quit the application from the application window and turned off the window close button (because I couldn't find any way to connect to it in code to make it quit the app). It doesn't look great, but it works.

Thanks to a helpful user - I forgot to draw attention to the day of use, that is, today's date. Now, the month, year, date and day of year the user starts using DOYV are now colored in blue. (Please note, if you leave DOYV open it will not update the current date from one day to the next. I have not tried this yet, but, the way I currently have DOYV coded, I do not think it will update over day bounds. The future Cocoa version will do this.)

I added today's date to the JumpTo Menu item.

For developers: DayOfYearViewer is presently written in the Mac OS X Carbon framework. It is a direct derivative of the CalendarView Carbon programming sample code example shipped with every copy of Mac OS X in Apple's Developer Tools and/or available online at Apple Developer Connection. I have made a few cosmetic changes to the original and written a few lines of code to add more functionality. CalendarView did not show day of year or allow one to jump by decades. These are the simple functions I added.

I will be trying to incorporate DayOfYearViewer's usefulness into an iCal plug-in - if such things exist.
