The simple united flight change policy states that you may modify your scheduled flight at any time before the scheduled departure. You won't be charged if you change your domestic flight within 24 hours of booking it or if you buy your ticket at least 7 days beforehand. Because the fee is higher for international travel, check the United website for further details. So long as you follow those rules, changing the departure date of your travel shouldn't cost a fortune.
