The first clue seemed obvious, so I clicked on the new heart shaped box. Only to find that I get to select a digit from 0 to 9. Presumably I'll need to put a specific date in there. But a) now that I know what the interface is, I can't back out. Surely there has to be some way. Can anyone help with that?

Surely they know that there are several different formats for dates around the world? So even if we knew what date we were looking for, it would hard to know what to enter... Oh well. Stuck until someone can help me deselect this selector.
