Room Availability Calendar adds Joomla booking slots
Room Availability Calendar is a free Joomla component for managing reservations for rooms, appointments and other bookable time slots.
This is the sort of job Joomla sites face when a business needs to show availability and accept bookings, rather than merely publish opening hours or event information. Joomla core can handle articles, menus, users, custom fields and date inputs, including its calendar form field, but it does not provide a native resource-booking workflow with conflict checking, reservation records, guest changes and notification emails.
Sites usually handle that gap in one of three ways: publish a timetable with core content, build a custom booking system around a component and template overrides, or install a booking extension. A template override can change the presentation of a calendar, but it does not supply the underlying reservation logic. According to the listing, Room Availability Calendar goes beyond core with:
- multiple rooms or spaces and daily, hourly or half-hour booking modes;
- frontend availability and price calculation;
- guest cancellation, modification and extension tools;
- email notifications and administrator-managed reservations.
That makes it relevant to small offices, salons, fitness businesses, classrooms, coworking operators and property or room-rental sites that do not need online payments in the basic setup. A brochure site, a site with fixed events rather than reservable resources, or a business already using an external booking service has little reason to install it.
The directory lists it as a free download from Darko, under the room availability calendar section, with a GPLv2-or-later licence and Joomla 4 and 5 compatibility. The page shows no reviews and one other extension from the developer. It points to a separate Pro edition for Stripe or PayPal, an Events module and bulk import, but gives no price. Before installing, check the documentation and support arrangements, email configuration, timezone and recurrence handling, privacy implications, upgrade path, and exactly which features remain in the free edition.
