.cal Domain

Calendar and scheduling services sit behind .cal, a three-letter closed extension from ICANN's 2012 New gTLD Program. It belongs to a cluster of short functional strings secured by a single platform operator in that round, each corresponding to a distinct service rather than to the corporate name — an approach that treats the top level as a product namespace rather than a branding one.

Use relates to calendar and scheduling products and associated resources. The extension is closed to public registration with no aftermarket. Short functional strings of this kind were among the scarcest assets in the round, and securing them prevented obvious service-descriptive terms from being taken at the top level by unrelated parties.
