iCal (.ics) Event Generator

Turn a schedule into iCal (.ics) calendar files — with timezones, all-day and recurring events, alarms, locations and organizers — importable into Google Calendar, Apple Calendar and Outlook. One .ics per event plus a combined calendar file.

What it does

• Generates RFC-5545 .ics events with title, times, location, description and URL.
• Supports all-day, recurring (RRULE), alarms/reminders and organizers.
• One file per event and a combined calendar.ics.

Use cases

• Courses & webinars — hand attendees a click-to-add calendar invite.
• Events & bookings — generate calendar files from a bookings spreadsheet.
• Gyms / classes — publish recurring class schedules.

How do I import the whole schedule? Use the combined calendar.ics in the key-value store.

Can I automate it? Yes — via integrations on the Apify platform and the Apify API.
