Key Benefits of DayOfYearViewer for Mac OS X

What is it? A calendar, that's all, but DayOfYearViewer is unique nonetheless!

How much does it cost? NOTHING! DayOfYearViewer is and always will be freeware.

DayOfYearViewer provides very simple services - presenting the day of year and date in a monthly format for all dates in the Gregorian calendar, with forward(>,>>,->) and backward(<,<<,<-) buttons for months, years, and decades. The day of year is a standard measure of time used in many scientific applications and it is always a pain to convert between day-month and day-of-year. DayOfYearViewer presents date and day of year in a monthly format.

I've made a few accuracy tests back to 4.July.1776, and the dates, days of week, and leap days seem to be correct back to that period, so you can find out, for example, what day of the week your great-great-great grandmother was born on if she lived in a country using the Gregorian calendar (its adoption history is very interesting). This software is based on the Gregorian calendar which made a necessary time adjustment to correct for errors in the Julian (Roman) calendar which goes back to 45 BC. Parts of Europe began to adopt the Gregorian calendar in October, 1582. However, the Gregorian calendar was only finally adopted in Russia and certain Greek orthodox countries around the start of the 1900s, and by China after 1949. I used as a primary reference the very thorough and detailed account of our calendar:

[New!]

Version History:

version 0.3 - 12.August.2006

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.

version 0.2 - 7.October.2004

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.

version 0.1 - 5.October.2004

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.
