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>
