Lightroom - image modify date
When you edit a file LR puts a date on the Metadata
So the Metadata date will be the date of your last edit provided that the Metadata is "Up To Date"
You can also create a smart collect by "edit date" using "greater than", "less than", "equals" or "in the range"
HOpe this helps
