SEE IT and Try It (<- PASSWORD: johnresig14) GET IT
NOTES:
* The SAMPLE calendar is for CENTRAL TIME ZONE and will put events in the proper place only for people in that time zone. DOWNLOADABLE KIT tells you the easy procedure to make it for YOUR TIME ZONE.
* Directions (in zip you download) tell you how to change password (_AND_ change time zone if needed -- if you need to change time zone you will note that the value you change to MAY be different by 1 or 2 from your offset from GMT, Greenwich Mean Time, depending on where YOUR SERVER is located; if a click does not put an event at the proper time, you will know what adjustment to make).
