Ben,

Thanksgiving is already there!
Furthermore there is no "E"aster, but "F" with param 3,0,0

And if you are interested, there is a way to avoid reading the dat-file twice:

Spoiler:

target.init = function () {
		var i, tempfile,lines, tempnumevents;
		//this.bubble("tracelog","initialising...");
		this.appTitle.setValue(kbook.autoRunRoot._title);
		this.appIcon.u = kbook.autoRunRoot._icon;

		// Load events from save file
		try {
			if (FileSystem.getFileInfo(datPath)) {
				// read whole file in first to count how many events there are
				tempfile = getFileContent(datPath,'savefile missing');
				if (tempfile!='savefile missing') {
					lines = tempfile.split("\r\n");	// CR LF is used by stream.writeLine()
					tempnumevents = (lines.length-1)/5;
					//this.bubble("tracelog","Events="+tempnumevents);
					for (i=0; i<tempnumevents; i++) {
						events.push([lines[i*5],lines[i*5+1],lines[i*5+2],lines[i*5+3],lines[i*5+4]]);
						} 
		/*	this isn't necessary! As there are already lines[]
					// now read file in using stream
					var stream = new Stream.File(datPath);
					for (i=0; i<tempnumevents; i++) {
						temptype = stream.readLine();
						tempmonth = stream.readLine();
						tempdate = stream.readLine();
						tempyear = stream.readLine();
						tempdescription = stream.readLine();
						events.push([temptype, tempmonth, tempdate, tempyear, tempdescription]);
					}
					stream.close();  
					this.bubble("tracelog","Events="+_Core.debug.dumpToString(events,"",2)); 
		*/		}
			} else {
				// no savefile, so push default events
				events.push(["Y", "1", "1", "2006", "New Year's Day"]);
				events.push(["V", "2", "14", "2005", "Valentine's Day"]);
				events.push(["F", "3", "0", "0", "Easter Sunday"]);		// easter is a special float with param 3,0,0
				events.push(["Y", "3", "17", "2005", "St. Patrick's Day"]);
				events.push(["F", "11", "4", "5", "Thanksgiving"]);
				events.push(["C", "12", "25", "2005", "Christmas"]);
			}
		} catch (e) { stream.close(); }

Regards
Mark

PS: Maybe editing (of the dat-file) would be easier if one event per row would be stored. Using something like a CSV-format, allowing events.push(lines[i].split(";"))
