EMB Buchungskalender & Reservierungen is a lightweight booking and availability calendar for WordPress websites.

It can be used for vacation rentals, rooms, equipment, parking spaces, shared facilities or other simple resources that need request-based day or date-range booking management.

The plugin provides:

Availability calendar with available, reserved and booked days.
Booking request form with configurable start and end date labels for day-based reservations.
Admin management for manual bookings and incoming requests.
Email notification for new requests, confirmations, rejections and cancellations.
Customizable resource names.
Customizable frontend labels and form texts.
Customizable colors for availability, reservation, booking and selected dates.
Customizable guest email subjects and message texts with placeholders.
Built-in email test tool for checking WordPress wp_mail() handoff.
Optional setup for multiple resources including a combined booking option.
Shortcode-based output without external tracking, external scripts or public credit links.

The plugin stores booking data locally in the WordPress database. It does not send data to external services. Email delivery uses the WordPress wp_mail() function and depends on the website’s mail configuration. A built-in email test tool can check whether WordPress can hand off a message to the server, but successful handoff does not guarantee inbox delivery by the recipient provider. The settings page also shows the last email test result as a small local diagnostic log.
