CMSB Kalender is a WordPress Plugin Directory app by CMS-Buttler.
AppRanks verdict
Generated from live marketplace data — refreshed daily
CMSB Kalender is a newly-listed WordPress app with a limited review volume. Category data on the canonical marketplace listing is currently incomplete, so AppRanks falls back to platform-wide rather than category-relative comparison for this listing. no published reviews yet means feature claims are unverified by the wider merchant base. Without a published review base, the only fit-signal available is the developer's own documentation plus the marketplace's listing-quality audit (linked below). Paid-only pricing means evaluating fit on the marketplace listing or via the developer's documentation before installing. AppRanks tracks rating, review count, pricing tier, and category position daily — the figures on this page reflect the most recent scrape from the canonical WordPress Plugin Directory listing.
Pros
- +Published by CMS-Buttler — established developer track record
Cons
- −No public reviews yet — fit and reliability are unverified

How CMSB Kalender works
Show full descriptionShow less
CMSB Kalender is a lightweight availability calendar for WordPress. It reads events from one Google Calendar iCal URL and displays the current month as available or booked.
Included in this WordPress.org version:
Shortcode [cmsbkalender]
One Google iCal calendar
Current month display
Free/booked color display
Mobile layout
Optional legend
Custom labels for available and booked days
Server-side iCal loading with configurable cache time
Basic recurring Google Calendar event handling for the current month
Larger CMS-Buttler calendar versions with extended functionality are available as separate products outside this WordPress.org plugin package: https://cms-buttler.de/cmsb-kalender/
More powerful CMS-Buttler calendar versions The WordPress.org version is intentionally focused on a clear and lightweight free/booked month view. It is suitable when you only need to publish basic availability from one Google Calendar.
The larger CMS-Buttler calendar products are separate packages outside this WordPress.org plugin and are designed for halls, clubs, venues, municipalities, rental locations, sports facilities, and organizations that need more control over public availability.
Compared with many simple calendar plugins, the larger CMS-Buttler calendar versions focus on privacy-conscious occupancy display instead of publishing every event detail. They can show that a day is booked while hiding names, internal notes, rental details, or private information.
Additional capabilities available in the larger CMS-Buttler calendar products may include:
Multiple months instead of only the current month
Half-day and partial-day occupancy with diagonal day display
Configurable split hour for morning and afternoon bookings
Mouseover details for events that are allowed to be public
Privacy rules for private, confidential, and default-visibility Google Calendar events
Keyword-based hiding for event titles and descriptions
Description trimming from an internal marker such as Intern:
Optional booked label when hidden event details are suppressed
Extended design controls for colors, borders, legend, navigation, and day shape
Manual synchronization for testing calendar changes immediately
Sync status with information about loaded, skipped, changed, and recurring events
Extended recurring Google Calendar event handling across multiple displayed months
Website-side calendar cache clearing without changing the Google Calendar itself
Larger package options for agencies or operators managing more complex calendar setups
These larger versions are especially useful when the public website should answer the visitor’s main question quickly: “Is this date available or already booked?” At the same time, internal information can remain inside Google Calendar.

External Services This plugin can use Google Calendar / Google iCal when a calendar URL is configured by the site administrator.
Google Calendar / Google iCal:
The plugin requests the iCal URL entered by the site administrator in order to load calendar events. The request is made server-side from the WordPress installation to the configured iCal URL. Data processed by Google depends on the calendar configuration and Google’s policies.
