Dayzed: React Headless Date Picker Primitives

dayzed is a React library providing headless primitives for building highly customizable, accessible (WAI-ARIA compliant) date picker components. It focuses on managing date logic and user interactions, exposing control through a custom `useDayzed` hook or a `Dayzed` render prop component, along with "prop getters" for flexible rendering. The current stable version is 3.2.3, actively maintained with recent updates for React 18 compatibility. Unlike opinionated date picker libraries, dayzed delegates all UI rendering to the developer, offering maximum flexibility in styling and layout, making it a strong choice for projects requiring bespoke date picker designs and strict accessibility control. Releases are feature-driven, with significant updates historically around React version support and API evolution (e.g., from render props to hooks). This approach significantly differentiates it from solutions that bundle UI, requiring extensive options for customization and often leading to less flexible APIs. The library emphasizes a lean core, providing only the necessary logic for date manipulation and state management, leaving visual implementation entirely to the consumer.
