The SkySearch calendar allows you to specify which day you are interested in. Simply clicking on a day will select it. Windows users will notice that the day selected will turn red. SkySearch will allow you to specify any day one month prior to current day to one month after current day. This is primarily due to the amount of time required to produce the results. Also, information may be suspect for searches so far from the current time. To select a day from last month, click on the '<<' button at the top left of the calendar. Conversely, clicking the '>>' button will allow you to specify a day next month.
