I'm working on a web application which has a feature to compare the price of products at different dates to see if they went up or down. Basically the user select two dates and click search. At the moment the labels are "Comparison Date" for the first date and "Capture Date" for the second date, which is far from intuitive.
What would be better labels in this case? Please notice that the order is not important i.e. date1 > date2 or date1 < date2
