Icalviz connects to any public iCal feed and displays your availability day by day on any page or post, using a simple shortcode. Works with Google Calendar, Outlook, Apple Calendar, Nextcloud, and any service that exposes a public <code>.ics</code> link.
Each day is automatically classified:
<ul>
<li>🟢 Free — no events scheduled</li>
<li>🟡 Partial availability — some time slots are taken</li>
<li>🔴 Fully booked — your entire working hours are covered</li>
</ul>
Visitors can click any day to see occupied time slots in a clean timeline modal. Optionally display a call-to-action button (e.g. “Book this slot”) that links to your booking system.
Why Icalviz?
Stop copy-pasting your schedule into a webpage. Connect your Google Calendar, Outlook, Apple Calendar, or any iCal-compatible calendar — Icalviz reads your public iCal feed and updates automatically, every 30 minutes.
<h4>Use cases</h4>
🏢 Meeting room & shared space booking — Display a room’s availability calendar so your team or clients can instantly see open slots, without logging into any system.
📅 Show your public availability as a freelancer or consultant — Let potential clients see when you are free before they even reach out. Display months of availability from your Google Calendar, Outlook or any iCal feed in seconds.
🎓 Training sessions & open office hours — Show students or participants which session slots are still open. Mark them as full automatically when your agenda is blocked.
🏡 Seasonal rental & short-stay property — Display your gîte, studio, or vacation rental availability directly on your WordPress site, synced live from any iCal-compatible calendar.
🚗 Fleet & equipment availability — Track and display the availability of a shared vehicle, camera kit, or any bookable asset — simply by blocking time in Google Calendar, Outlook, or any other iCal calendar.

<h4>How it works</h4>
<ol>
<li>Get your public iCal URL (<code>.ics</code> link) from your calendar app:
<ul>
<li>Google Calendar: ⋮ → Settings and sharing → Make available to public → Public address in iCal format</li>
<li>Outlook: Calendar settings → Shared calendars → Publish → ICS link</li>
<li>Apple Calendar / iCloud: Calendar settings → Public Calendar → Copy link</li>
<li>Any other app: look for “Subscribe”, “iCal export” or “public ICS link”</li>
</ul>
</li>
<li>In WordPress: go to Settings → Icalviz, paste your iCal URL and follow the 3-step wizard.</li>
<li>Copy the generated shortcode and paste it into any page or post.</li>
</ol>

You can create an unlimited number of booking websites, accessible to customers on any device, in any language.
From basic features like secure frontend property administration, comprehensive and flexible <a href="http://www.jomres.net/manual/site-managers-guide-2/402-search-widgets" rel="nofollow ugc">search features</a>, <a href="http://www.jomres.net/manual/property-managers-guide-2/41-your-toolbar/bookings/328-jomres-ical" rel="nofollow ugc">iCal import and export</a>, through to powerful developer tools such as its built-in <a href="http://www.jomres.net/manual/developers-guide-2/90-channel-management-framework" rel="nofollow ugc">REST API</a> and <a href="http://www.jomres.net/manual/developers-guide-2/64-webhooks" rel="nofollow ugc">Webhooks</a> functionality, there’s something here for everybody. Whether you are looking for a booking engine for a single property site, or a complete portal, Jomres is where it’s at.
Jomres is created and maintained by me, Vince Wooll. I am not a designer or a marketer, I’m a software engineer who believes that there’s still a place for the solo developer in today’s internet. I think of Jomres as less a booking engine and more a toolkit, with a set of tools that my users can use to build their own unique online websites. Jomres follows that line of thinking with it’s strong emphasis on giving you, the user, the <a href="http://www.jomres.net/documentation/" rel="nofollow ugc">information and tools</a> you need to create something amazing.
<h3>What’s new?</h3>
<h4>Bootstrap no longer required</h4>
Jomres can now be run on non-Bootstrap themes. This means that you can use Jomres on any theme, not just Bootstrap themes. If you’re using a Bootstrap theme, you can still use the Bootstrap version of Jomres, but you don’t have to.
<h3>Demos</h3>
<a href="http://wordpress-portal.jomres.net/" rel="nofollow ugc">See the Portal Demo here – a variety of bookable items, multiple owners</a>
License holders can download the “QuickStart” zip file that enables you to deploy a full installation of WordPress with everything already set up to exactly match the Demo. You can be up-and-running, with a fully-featured booking website that looks terrific, within minutes.
