Hi Product Hunt 👋 I'm a solo developer and I've been building Calendar 366 since 2017 — first on Mac, now across iPhone, iPad, Mac and Apple Watch. The idea was always the same: a calendar that adapts to how you work, not the other way around. A few things that make it different: - 13 views you can combine freely — year, month, week, agenda, day, and list variants - Natural language input: type "Meeting with Alex tomorrow 10am" and it just works - Tasks live right inside the calendar, not in a separate app - 20 widgets, 10 watch complications, weather everywhere - Works with Apple Calendar, iCloud, Google, Outlook, Microsoft 365, Todoist, Fastmail and CalDAV The newest addition: you can now control Calendar 366 through Claude Desktop or LM Studio via MCP. Ask your AI to move a meeting or check your week — and with LM Studio it runs entirely on your machine. No account, no tracking, no data on our servers. Ever. Happy to answer any questions — and I'd genuinely love to hear what's missing for your workflow.
