What is 12x31?

12×31 is a free year planner that puts all 12 months on one screen in a colour-coded grid — so you can see every trip, commitment, and free weekend at a glance. The year view that Google Calendar, Outlook, and Apple Calendar don't give you.

Import your existing calendar (.ics) from Google Calendar, Outlook, or Apple Calendar. Events appear as colour-coded bars across the grid, making scheduling conflicts and free weekends immediately visible.

Features: natural language event creation, cloud sync across devices, public holidays for 31 countries, Year in Review analytics, availability sharing, image export, and full keyboard shortcuts. Works offline as a PWA — install it on any device, no app store needed.

Built by a solo developer in Switzerland who travels 120 days a year and needed to see the big picture.
