Help! If cell contains any sort of date, show green checkmark. Otherwise, show red...

Hello All:

I'm just looking for a way that when I type ANY date in the cell, it will produce a green checkmark icon.

If the cell is blank, I need it to show the red X icon.

See attached graphic for example.

Disregard the yellow exclamation.

By the way, these icons are located under conditional formatting / Icon sets.

Thanks in advance!
