Can add multiple calendar widgets – each of them set to different categories (or All Categories).
The tooltip on the per-day links shows only post titles from that category, and when you click on the calendar link to bring up the day archive of posts, only posts from that category are shown.

Calendar Category

Un-registers the default Calendar widget, and registers a new one which supports showing only those posts in certain (or all) categories.

Appointment Hour Booking is a WordPress plugin for creating booking forms for appointments with a start time and a defined duration over a schedule. The start time is visually selected by the end user from a set of start times calculated based in the “open” hours and service duration. The duration/schedule is defined in the “service” selected by the customer. Each calendar can have multiple services with different duration and prices.
This plugin is useful for different cases like booking of medical services where services with different duration and prices may be available, for personal training sessions, for booking rooms for events, for reserving language classes or other type of classes and other type of services/resources booking where start times are selected and the availability is automatically managed using the defined service duration to avoid double-booking (the booked time is blocked once the booking is completed).

<h4>Appointment Hour Booking can be used for:</h4>
Booking services or resources: Define schedule, open hours, services, prices and durations and let the calendar plugin manage the schedule.
Sample cases: Medical services, personal training, resource allocation, booking rooms, classes, etc…
The services can have a maximum capacity (example: number of persons that can book/attend the service at the same time). The default capacity is 1. If the service capacity has been set to 1 the time-slot will be blocked for new bookings after getting one booking. If the service capacity has been set to a greater number (example: service with capacity 10) the time-slot will be blocked after filling the capacity (example: after getting bookings for a total of 10 persons). This feature is described in detail at https://apphourbooking.dwbooster.com/blog/2019/01/24/bookings-for-multiple-persons/
<h4>The Troubleshoot Area</h4>
Use the troubleshot if you are having problems with special or non-latin characters. In most cases changing the charset to UTF-8 through the option available for that in the troubleshot area will solve the problem.
You can also use this area to change the script load method if the booking calendar isn’t appearing in the public website.
<h4>The Notification Emails</h4>
The notification emails with the appointment data entered in the booking form can sent in “Plain Text” format (default) or in “HTML” format. If you select “HTML” format, be sure to use the BR or P tags for the line breaks into the text and to use the proper formatting.
<h4>Exporting Appointments to CSV / Excel Files</h4>
The appointment data can be exported to a CSV file (Excel compatible) to manage the data from other applications. That option is available from the “bookings list”, the appointments can be filtered by date and by the text into them, so you can export just the needed appointments to the CSV file.
<h4>Other Versions and Features</h4>
The free version published in this WordPress directory is a fully-functional version for accepting appointments as indicated in the plugin description. There are also commercial versions with additional features, for example:
<ul>
<li>Ability to process forms/appointments linked to payment process (PayPal, Stripe, Skrill, …)</li>
<li>Form builder for a visual customization of the booking form</li>
<li>Addons with multiple additional features</li>
</ul>
Payments processed through the plugin are SCA ready (Strong Customer Authentication), compatible with the new Payment services (PSD 2) – Directive (EU) that comes into full effect on 14 September, 2019.
