Add to Calendar Button vs CalDav Calendar Viewer

Make your events get saved. This WordPress plugin lets you create beautiful buttons with calendar links, where people can add events to their calendars. All of this with just a few clicks and highly customizable, using the popular Add to Calendar Button script. Check out the official website for a comprehensive demo and overview. 🛠️ INTEGRATED IN SECONDS You can either use the shortcode [add-to-calendar-button] or the Gutenberg Block. With the PRO version, it only takes the ID to make it fly. In the no-PRO case, you simply place the necessary attributes directly in the shortcode, or at the Gutenberg Block settings. (Mind that you cannot use ‘[‘ and ‘]’ characters, when going for the shortcode option! For content formatting, you can use {‘{‘}xxx{‘}’} instead of [xxx] there.) 🚀 GO PRO Go even further with the PRO version… → Manage all details and styling via a convenient web app. → Use the same button to let people RSVP to your events – fully managed. → Get auto-generated landing pages and shareable links for your events. → Have better guidance for your users, when they add events to their calendars and things don’t go as expected. 👉 Learn more at add-to-calendar-pro.com. ✨ SUPPORTED CALENDARS Google Calendar.

One-time, multi-date, recurring. Most robust time zone and daylight saving management. Dynamic dates (like “today + 3”). 🎨 ADJUST THE LOOK The button comes with multiple themes as well as a dark and light mode. You can easily adjust almost every element by setting the respective simple attributes. In case you want to go all-in, you can also manipulate all kinds of colors and further styling. 🖖 EXPERT ACCESSIBILITY Optimized and adjustable UX (for desktop and mobile). Dynamic dropdown positioning. Taking care of all those edge cases, where some scenarios do not support specific setups (like WebView blocking downloads); utilizing beautiful user guidance workarounds. Auto-generated Schema.org rich (structured) data for better SEO. Full support for mouse, touch, or keyboard input (W3C WAI compliant). Aside from the WordPress editor, the button itself supports 20+ languages, incl. RTL text for Arabic; but also offers the option to customize all labels and text blocks. 📄 ABOUT THE LICENSE Mind that the script to actually generate the Add to Calendar Button uses the Elastic License 2.0 (ELv2)! This usually comes with no restrictions for you, but it forbids you to rework the core script and provide the product (generating an add-to-calendar-button) to others as a managed service. In almost every case, this will not affect you. If you are not sure, because you are building some kind of SaaS, where you are using the plugin, simply contact us.

CalDav Calendar Viewer fetches and displays events from any standard iCal (.ics) feed directly on your site using a simple shortcode. It supports multiple calendar feeds, each with its own URL and optional username/password for authenticated endpoints. Key Features: Multiple Calendar Feeds – Configure as many feeds as you need, each with a unique ID. iCal / RFC 5545 Support – Parses standard .ics calendar feeds including all-day events, times, locations, and descriptions. Recurring Events – Expands RRULE recurrences (DAILY, WEEKLY, MONTHLY, YEARLY) including BYDAY, BYMONTHDAY, INTERVAL, COUNT, UNTIL, and EXDATE. DURATION Support – Derives the end time from a DURATION property when DTEND is absent. Basic Authentication – Supply a username and password per feed for protected calendars. Encrypted Credentials – Passwords are stored using AES-256-CBC encryption in the database. Caching – Configurable cache lifetime reduces external HTTP requests (defaults to 1 hour). Cache Management – View the number of currently cached feed entries and clear them with one click from the admin settings page. Async Loading – Calendar events are fetched via AJAX so the containing page renders immediately. Label / Category Filtering – Filter events by iCal CATEGORIES labels using the label shortcode attribute. Accepts a comma-separated list; all plain labels must be present on an event for it to be shown. Prefix a label with ! to exclude events that carry that category. Matching is case-insensitive. Clickable Events – Events that carry a URL property in the iCal feed are rendered as clickable links. 7-Day Rolling Window – Automatically fetches and displays only the next 7 days of events. Responsive Event List – Clean event list layout that adapts to all screen sizes. Event Tooltips – Hover over an event to see its description. Description Prefix Filtering – Remove lines from event descriptions that start with configurable prefixes. Useful for hiding internal metadata added by calendar applications. Configuration Navigate to Settings → CalDav Calendar Viewer in the WordPress admin panel. Adding a Feed Click + Add Feed and fill in: Feed ID – A unique lowercase identifier (letters, numbers, hyphens, underscores) used in the shortcode. iCal Feed URL – The full URL to the .ics calendar feed. Username – Username for Basic Authentication. Leave blank for public feeds. Password – Password for Basic Authentication. Stored encrypted. Leave blank to keep the current value. You can configure multiple feeds — each gets its own ID. General Settings Cache Lifetime (seconds) – How long fetched calendar data is cached. Set to 0 to disable caching. Default: 3600 (1 hour). Description Line Prefixes to Remove – Newline-separated list of prefixes. Any line in an event’s description that starts with one of these prefixes is removed from the tooltip. Useful for hiding internal metadata added by calendar apps (e.g. X-APPLE-, Reminder:). Cache Management The settings page shows how many calendar feeds are currently cached. Use the Clear Cache button to delete all cached responses and force fresh fetches on the next page load.
