Just use Google Flights and select "one-way", "non-stop", and "United" and the route you are interested in. Then click on the date field and it will bring up a monthly calendar where you can readily see which days a flight does not operate (as there is no price listed). You can also easily move through the months by using the arrows. You can also use the "Times" slider to specify time slots to see which days of the week a particular departure operates on.
