What Is iCal Generator?

iCal Generator creates iCalendar (.ics) files following the RFC 5545 standard. These files can be opened by virtually any calendar application โ€” Google Calendar, Apple Calendar, Outlook, and others. Enter your event details including title, date, time, location, and description, and generate a properly formatted .ics file. The tool supports both timed events and all-day events, with customizable start and end dates/times.

Why Use Our iCal Generator?

  • RFC 5545 compliant .ics file generation.
  • Compatible with all major calendar apps (Google, Apple, Outlook).
  • Supports both timed events and all-day events.
  • Download as .ics file or copy the raw content.

Technical Guide

The generator creates iCalendar format following RFC 5545. The output includes VCALENDAR and VEVENT components with standard properties: - DTSTART/DTEND: Event start and end times. For all-day events, VALUE=DATE parameter is used. - SUMMARY: Event title with iCal character escaping (semicolons, commas, backslashes, newlines). - DESCRIPTION: Event description with the same escaping. - LOCATION: Event location. - UID: Unique identifier generated from timestamp and random string. - DTSTAMP: Timestamp of when the .ics file was created. Date-time values use the iCal format: YYYYMMDDTHHMMSS. Line endings use CRLF (\r\n) as required by the specification. The generated .ics file uses the PUBLISH method, meaning it's a published event (not a meeting request requiring responses).

Tips & Best Practices

  • 1
    Title and start date are required โ€” all other fields are optional.
  • 2
    If no end date is set, it defaults to the start date.
  • 3
    All-day events use DATE format without time components.
  • 4
    The .ics file can be attached to emails as a calendar invitation.
