manipulate date of generated events

Which method can change or give a date to our events : like those
new Event("Walk the dog", "Park", 0, 0, 30, android.R.color.holo_red_dark),
new Event("Meeting", "Office", 1, 30, 90, android.R.color.holo_purple),
new Event("Phone call", "555-5555", 2, 0, 45, android.R.color.holo_orange_dark),
new Event("Lunch", "Cafeteria", 2, 30, 30, android.R.color.holo_green_dark),
new Event("Dinner", "Home", 18, 0, 30, android.R.color.holo_green_dark)};

Start by inspecting the Event constructor and the calendar day-view code that creates or displays the sample events. Identify whether the current API already supports assigning or changing dates; done means establishing a clear way to set event dates and confirming the sample events appear on the intended days.
