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.
