Just something I have been wondering about. Does anyone have any idea if alternative sets of notable dates are available to download into MS Outlook? The list available in Tools/Options/Preferences/ is of strictly national holidays and religious dates. Presumably you could use the same technique to add, say, sunrises and sunsets, or phases of the moon, or non "holiday" dates. As an alternative, would it be possible to structure dates in a file and somehow import them from a file into Outlook? (I know that I could just type them directly into the calendar, but this is slow, fiddly and error prone, if there are many).
