I know this is too late for Halloween 2014, but I came up with an idea. Find the time zone you're in and find out how many hours difference it is from the International Date Line (There should be a chart showing this in The World Almanac). Then give your well-wishes at the time when it would be midnight at the International Date Line. In theory, this would mean you'd be offering well-wishes at the "official" start of the hoilday, so you wouldn't have to worry about different times. I hope this makes sense.
