Thanks that was really useful. My revised config is:
(start and end date/time, one of many possible formats)

		config: {
					dateFormat: "llll",

// dateEndFormat: “YYYY-MMDDTHH:mm:ss”,
dateEndFormat: “llll”,
timeFormat: ‘absolute’,
showEnd: true,
urgency: 0,
getRelative: 0,
fetchInterval: 2 * 60000,

			calendars: [
				{

I found this site a bit easier to follow:

@sdetweil Thanks very much Sam. I don’t seem to be able to ever get the start time to display.

Hi,
Do you know if it is possible to display both the start and end time/date for entries with the default calendar module.
The config I’m using is

	config: {
					timeFormat: 'absolute',
					showEnd: true,
					urgency: 0,
					getRelative: 0,
					fetchInterval: 2 * 60000,

			calendars: [
				{
					symbol: "calendar-check",

When showEnd is true only end times are displayed. When showEnd is false no times are displayed.

Thanks
