Alarm/Cal Event repeating every alternate day and that which does not sync with google I need to create an alarm or calender event that repeats every alternate day at same time. I can not associate it with day of week, or date. I am using HTC Desire S. 

I also need create entries in HTC Desire S calendar that which does not sync with Google calendars.
Create an event in Google Calendar with the repeat/reminder frequency that you want.

To avoid synchronizing the event with external calendars, put the event on a phone-private calendar: http://www.google.com/support/mobile/bin/answer.py?hl=en&amp;answer=168512&amp;topic=21414#1077952
