Hi,
Which version of Photoshop Elements are you using?
If you are looking at the thumbnails in the organizer, try going to the View menu and ensure that Details is checked. The date should appear under each thumbnail. If the date still doesn't appear, you may need to increase the size of the thumbnail by using the zoom slider.
In the bottom right hand corner of each thumbnail, there should be an icon if that image is in an album. Hover the mouse over that icon and a fly-out should give you the information you want.
If you tell us the version, we may be able to give better instructions.
