What FullCalendar is

FullCalendar is a JavaScript event calendar for websites and applications. It can be styled to match a site’s design system and used through an API, on the web, or self-hosted. Standard views include month, time grid, list, day grid, and multi-month layouts. The API supports event sources, display, clicks, hovering, dragging, resizing, and background events. Premium adds timeline and resource views plus printer-friendly rendering. Documentation covers React, Vue, Angular, Preact, Web Components, and Salesforce LWC; plugins support Google Calendar, iCalendar, RRule, Moment, and Luxon formatting. Installation is available through NPM, ZIP, or CDN. The site describes screen-reader optimization and manual checks with NVDA, JAWS, and VoiceOver, while virtual rendering targets large event loads. Standard uses the MIT license. Premium is $480 a month as a one-time payment.
