I needed to publish our community club's event calendar on a static website without any calendar plugin — converting the ICS file to HTML gave me a clean, browser-viewable page I could upload directly to the hosting server.

Our team shared a project schedule as an ICS file but several stakeholders don't use calendar apps — converting it to HTML let everyone view the timeline in any browser without needing to import anything.

I converted a Google Calendar export to HTML for a printed event program — the resulting HTML listed all events in chronological order with dates, times, and descriptions, which I then styled with CSS and printed as a handout.

ICS to HTML — Frequently Asked Questions ▼

What does the HTML output look like?

A clean table of events in chronological order with columns for date, time, summary, location, organizer, and description. The desktop converter also offers daily, weekly, or monthly grid layouts.

Will the HTML embed in a CMS like WordPress or SharePoint?

Yes. The output is standards-compliant HTML5. Paste the body into a WordPress, SharePoint, Confluence, or Notion page and it renders inline.

Are recurring events expanded?

Yes. RRULE recurrences are expanded so every occurrence appears as its own row in the HTML table within a configurable date range.

Are styles included?

Yes. A minimal inline CSS block formats the table for readability. The desktop converter accepts a custom CSS file if you need to match your site's house style.

Will time zones be respected?

Yes. Each event shows its time in the declared zone, with an optional zone-normalization step in the desktop converter for multi-region calendars.

Can I publish a Google Calendar export as a web page?

Yes. Export the calendar from Google Calendar > Settings > Import & Export, drop the .ics here, and the HTML is ready to publish.

Are attendees and organizer included?

Yes. ATTENDEE and ORGANIZER fields render as a comma-separated list inside the event row. The desktop version can hide them if you publish the page externally for privacy.

Convert ICS to HTML — Publish iCalendar Schedules as Web Pages

ICS is the iCalendar file format every calendar app reads. HTML is the format every browser, intranet, and content management system displays. Converting ICS to HTML turns a schedule into a clean web page you can publish on a site, embed in an intranet, email as a newsletter, or post on a SharePoint page. Drop your .ics file above.

What Is ICS?

ICS (iCalendar, RFC 5545) is the universal calendar interchange format. A .ics file is plain text containing VCALENDAR, VEVENT, VTODO, VJOURNAL, and VTIMEZONE records with structured fields for summary, location, organizer, attendees, start/end times, recurrence rules, and alarms. Google Calendar, Apple Calendar, Outlook, and Thunderbird Lightning all read and write ICS.

What Is HTML?

HTML (HyperText Markup Language) is the foundation of the web. An .html file describes structure, links, headings, lists, tables, and embedded media that any browser renders. HTML is the format intranets, CMS platforms, knowledge bases, and email newsletters use to present formatted content without proprietary readers.
