Trouble finding when my License Expires

It should be located on the Licenses tab next to the license:

Hi Ben! This is what my page looks like currently (missing expiration date). Thanks for your prompt response by the way -- it's much appreciated.

If you select that license to see its details, are there any expiration dates (still right-aligned) within the details? 

Sorry for the confusion. If a license doesn't show an expiration date in the areas that I mentioned, the license simply doesn't expire. It is likely domain and versioned locked and not time-bound.

Got it -- Thank you so much for your help!
