Event Calendar Plugins are third-party tools you can embed into your Squarespace site to show upcoming events, schedules, and calendars in attractive, interactive formats — ideal for businesses, artists, schools, community groups, and venues. While Squarespace has built-in Events pages and Calendar Blocks, many site owners add enhanced calendar widgets from external services to provide richer features like recurring events, registration, ticketing, and visual layouts.

Since Squarespace doesn’t use a WordPress-style plugin marketplace, these are generally embed widgets you configure online then insert onto your site via a Code Block or Custom Code Injection. Elfsight
