Welcome! This is a little script I made to modify the dates of a iCalendar file. The main reason for this is a work-around to Facebooks "Facebook Time" problem, where in Google Calendars its off for most. What this script does is simply add time to each date in the calendar.
For some reason, there is a bit of lag with gCal getting the contents of the resulting url. Try refreshing gCal and it should work! Thanks to anyone pointing out this bug.
Type in your iCal url to get a new url for use with this site. Thats it! Easy as pie.
