## What it is
Kalendae is a framework-agnostic JavaScript date picker library with no external dependencies. It supports single, multiple, and range date selection, inline or popup display, and configurable blackouts and month layouts.

## Use cases
- add a date picker to a form input without jQuery
- let users select a date range for a booking form
- embed an inline calendar widget on a page
- black out unavailable dates in a calendar
- show a multi-month calendar with future dates only

## When to choose
- you need a dependency-free, easily skinnable date picker for a legacy or framework-free site
- you need range or multi-day selection with blackout dates
- you must support older browsers like IE8

## When to avoid
- you need an actively maintained library with modern framework (React/Vue) bindings
- you need time-of-day or timezone-aware picking
- you want a mobile-native date input experience

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, date-time, form-handling
- domain: web-development, frontend
- platform: browser
- tags: date-picker, calendar-widget, framework-agnostic, no-dependencies, momentjs, javascript
