    Hi Abhijit Mandal,

    As far as I know, perpetual licenses and certain subscription SKUs are assigned an artificial “end date” of December 31, 9999. This isn’t a real expiration date; rather, it’s a placeholder that signals the license is perpetual or indefinite in duration. In other words, the system needs a value to represent “no end date,” and 9999 is used as the maximum supported date in the database.

    For your Windows Server 2025 Standard – 16 Core License Pack SKU, the 9999 date simply indicates that the license does not expire under normal circumstances. Subscription-based licenses that are truly time-bound will show actual end dates that reflect the billing cycle or contract terms. The perpetual ones, however, will always display 9999 to differentiate them from expiring subscriptions.

    The year 9999 end date is a technical placeholder that represents “no planned end date” for that price point or license entry in Microsoft’s systems, not the actual commercial term of the subscription or license.

    In Microsoft pricing and catalog systems, date fields are implemented using SQL DATE types, whose valid range is from 0001-01-01 through 9999-12-31. When a product, price point, or end-of-sale period is intended to be open-ended (no specific end date yet), Microsoft commonly sets the end date to a far-future value within that range, such as 9999-11-30 or 9999-12-31.

    For example, in the software pricing data:

    • EffectiveEndDate and EndOfSaleEndDate can be set to 9999-11-30T23:59:59.0000000Z to indicate that the price point or end-of-sale period does not currently have a defined end date.

    This same pattern explains why a perpetual or long-lived SKU such as “Windows Server 2025 Standard – 16 Core License Pack” can show a charge or end date of 31 December 9999 in back-end or reporting views: it is simply the system’s way of encoding “indefinite” within the SQL date range, not a literal billing commitment through the year 9999.

    The actual commercial term (for example, perpetual license vs. 1-year/3-year subscription) is determined by the licensing program and offer terms, not by the placeholder date value.
