In general, scheduling future events is a complex subject. You have to make a distinction in the context of what is going to be scheduled: Does the event occur at a specific universal instant in time? If so, you should record the event time in terms of UTC. For example, a task that runs every … Read more
Months are indexed from 0 not 1 so 10 is November and 11 will be December.

Storing “Simple” Repeating Patterns For my PHP/MySQL based calendar, I wanted to store repeating/recurring event information as efficiently as possibly. I didn’t want to have a large number of rows, and I wanted to easily lookup all events that would take place on a specific date. The method below is great at storing repeating information … Read more
This is the problem to start with: Calendar cal = Calendar.getInstance(TimeZone.getTimeZone(“EST”)); The 3-letter abbreviations should be wholeheartedly avoided in favour of TZDB zone IDs. EST is Eastern Standard Time – and Standard time never observes DST; it’s not really a full time zone name. It’s the name used for part of a time zone. (Unfortunately … Read more

Taken from the docs here: Adds or subtracts the specified amount of time to the given calendar field, based on the calendar’s rules. For example, to subtract 5 days from the current time of the calendar, you can achieve it by calling: Calendar calendar = Calendar.getInstance(); // this would default to now calendar.add(Calendar.DAY_OF_MONTH, -5).
Try this in your code: Calendar cal = Calendar.getInstance(); Intent intent = new Intent(Intent.ACTION_EDIT); intent.setType(“vnd.android.cursor.item/event”); intent.putExtra(“beginTime”, cal.getTimeInMillis()); intent.putExtra(“allDay”, true); intent.putExtra(“rrule”, “FREQ=YEARLY”); intent.putExtra(“endTime”, cal.getTimeInMillis()+60*60*1000); intent.putExtra(“title”, “A Test Event from android app”); startActivity(intent);
