.day domains

The .day domain is a versatile extension operated by Google Registry, suited to daily content, events, awareness days, and personal projects. The word is warm and universal, so a name plus .day reads as timely and human, whether marking a special occasion or a daily habit. Creators use it for daily content, organizations for awareness campaigns, and individuals for personal projects, all under a friendly, flexible domain. As with all Google-operated TLDs, .day is on the HSTS preload list, so browsers require HTTPS for every .day site and secure connections are enforced automatically. Registration is open to anyone worldwide with no restrictions and follows standard yearly terms. Because the word is short and positive, brandable names remain available where a common gTLD would be crowded. For a daily project, an event, or an awareness campaign, ending the address in .day puts a warm, timely word directly into the domain with security built in.
