The things you (or your LLM) would have missed

Screen reader optimized

Intuitive experience for blind and low-vision users. Meticulously manually tested with NVDA, JAWS, and VoiceOver.

Heavy loads, odd shapes

Load 10,000 events, even stacked onto a single day. Virtual rendering keeps everything scrolling smoothly.

Print (on paper)

Yes, people still print calendars, more than you'd think. Our media-aware rendering has got you covered (requires Premium).

The finishing touch

We've tuned the calendar's touch-based UX. Works seamlessly with long press, drag-n-drop, and competing scroll panes.

Oh, and we fixed dates too.

JavaScript's Date is broken. We created temporal-polyfill, an implementation of its official replacement.
