If you have a time-limited license, your license expiration can be viewed in the Wolfram User Portal. If you are using a product that was obtained through an organizational site license, your product will expire 30 days beyond the license expiration date.

In Wolfram Language products, you can also obtain this information by evaluating $LicenseExpirationDate.

If you have any questions, please contact Wolfram Research or your authorized reseller.
