## What it is
Cally is a set of small, feature-rich calendar web components built in TypeScript, providing building blocks for date selection (single, multiple, ranges, multi-month). It is framework-independent, accessible, localizable via Intl, and themeable with CSS parts and custom properties.

## Use cases
- add a date picker to a web page
- select a date range for booking forms
- build a custom datepicker with my own inputs and popovers
- display multiple months of a calendar
- framework-agnostic calendar components for any JS framework
- accessible calendar with keyboard and screen reader support

## When to choose
- you want small bundle size (<9KB) calendar building blocks
- you already have your own inputs, buttons, and popovers and just need calendar logic
- you need accessibility and internationalization out of the box
- you want framework-independent web components

## When to avoid
- you want a complete out-of-the-box date picker widget with input and popover included
- you need a React-specific datepicker with rich theming presets
- you need time-of-day or datetime scheduling features

## Facets
- artifact type: library
- maturity: active
- function: ui-components, date-time, form-handling
- domain: web-development, frontend, web-design
- platform: browser, cross-platform
- tags: web-components, calendar, datepicker, typescript, accessible, lightweight, web-server
