Several holiday files you can import into calendars made with CalendarMaker 4.0 through 4.5.3. First download "CalendarMakerH2011-12.sit" for pure OS 9 or "CalendarMakerH2011-12.zip" for Classic under OS X. Then create the folder "CalendarMaker Holidays 2011-12" by double-clicking either the "sit" or "zip" file (unless your browser does this for you automatically). Then select Import Events from the CalendarMaker File menu and import the file that you want. These dates are believed accurate but this is a free service to our customers and should not be relied on. In case you want to edit or create your own files, these are tab-delimited text files in the format: Date <tab> Holiday Example: mm/dd/yyyy <tab> Christmas [There are no blank spaces before or after the tab.] General Holidays 2011-2012 Catholic Holidays 2011-2012 Jewish Holidays 2011-2012 Note: Certain holidays are in more than one file. When importing more than one holiday file, be sure and mark these duplicates as "Don't Import". If you import both General and Catholic holidays into your calendar, you will duplicate the following: Ash Wednesday Palm Sunday Good Friday Easter Christmas If you import both General and Jewish holidays into your calendar, you will duplicate the following: Passover First Day of Rosh Hashanah Yom Kippur First Day of Hanukkah Note: Concerning the Islamic holidays, a special conference on Hilal Sighting organized by the Fiqh Council of North America on June 10, 2006 in Virginia announced on Aug. 6, 2006, the decision to use astronomical calculations and not be dependent on the actual sighting of the moon which could cause a holiday to be delayed a day because of clouds or location. Despite this, we have not found a consistent source for the Islamic holidays. Therefore we have discontinued supplying a file of Islamic holidays.
