Google Sheets to Calendar - something wrong with the syntax of the date - google-apps-script

Question

I try to use a script from Create Google Calendar Events from Spreadsheet but prevent duplicates, however I can't make it work. It seems to me that there is a problem with the date format, though I use the standard one in my spreadsheet.
function onOpen() {
var sheet = SpreadsheetApp.getActiveSpreadsheet();
var entries = [{
name : "Export Events",
functionName : "exportEvents"
}];
sheet.addMenu("Calendar Actions", entries);
};
/**
* Export events from spreadsheet to calendar
*/
function exportEvents() {
var sheet = SpreadsheetApp.getActiveSheet();
var headerRows = 1; // Number of rows of header info (to skip)
var range = sheet.getDataRange();
var data = range.getValues();
var calId = "YOUR_CALENDAR_ID";
var cal = CalendarApp.getCalendarById(calId);
for (i=0; i<data.length; i++) {
if (i < headerRows) continue; // Skip header row(s)
var row = data[i];
var date = new Date(row[0]); // First column
var title = row[1]; // Second column
var tstart = new Date(row[2]);
tstart.setDate(date.getDate());
tstart.setMonth(date.getMonth());
tstart.setYear(date.getYear());
var tstop = new Date(row[3]);
tstop.setDate(date.getDate());
tstop.setMonth(date.getMonth());
tstop.setYear(date.getYear());
var loc = row[4];
var desc = row[5];
var id = row[6]; // Sixth column == eventId
// Check if event already exists, update it if it does
try {
var event = cal.getEventSeriesById(id);
}
catch (e) {
// do nothing - we just want to avoid the exception when event doesn't exist
}
if (!event) {
//cal.createEvent(title, new Date("March 3, 2010 08:00:00"), new Date("March 3, 2010 09:00:00"), {description:desc,location:loc});
var newEvent = cal.createEvent(title, tstart, tstop, {description:desc,location:loc}).getId();
row[6] = newEvent; // Update the data array with event ID
}
else {
event.setTitle(title);
event.setDescription(desc);
event.setLocation(loc);
// event.setTime(tstart, tstop); // cannot setTime on eventSeries.
// ... but we CAN set recurrence!
var recurrence = CalendarApp.newRecurrence().addDailyRule().times(1);
event.setRecurrence(recurrence, tstart, tstop);
}
debugger;
}
// Record all event IDs to spreadsheet
range.setValues(data);
}
Please, could you have a look what is wrong (my spreadsheet: https://docs.google.com/spreadsheets/d/1OIZLOjG5cg32EbV-bI5c2qDWtbhbggDTTobPK_dYfyQ/edit?usp=sharing). The script works but there is no result in my Google Calendar.

I thought that when I saw your showing script, date.getYear() might be required to be modified to date.getFullYear(). I thought that this might be the reason for your current issue of The script works but there is no result in my Google Calendar..
And, in your script, var date = new Date(row[0]), var tstart = new Date(row[2]) and var tstop = new Date(row[3]) might be written as var date = row[0], var tstart = row[2] and var tstop = row[3]. Because the cell values are the date object. So, how about the following modification?
From:
var date = new Date(row[0]); // First column
var title = row[1]; // Second column
var tstart = new Date(row[2]);
tstart.setDate(date.getDate());
tstart.setMonth(date.getMonth());
tstart.setYear(date.getYear());
var tstop = new Date(row[3]);
tstop.setDate(date.getDate());
tstop.setMonth(date.getMonth());
tstop.setYear(date.getYear());
To:
var date = row[0];
var title = row[1];
var tstart = row[2];
tstart.setDate(date.getDate());
tstart.setMonth(date.getMonth());
tstart.setYear(date.getFullYear());
var tstop = row[3];
tstop.setDate(date.getDate());
tstop.setMonth(date.getMonth());
tstop.setYear(date.getFullYear());
Note:
In the case of var event = cal.getEventSeriesById(id);, I think that even when id is empty and the invalid value, no error occurs. So, try - catch might not be required to be used.
