What is an ICS?

An ICS file (iCalendar File) is a standardized file format for sharing and subscribing to calendar information. Think of it as a universal calendar format that different calendar applications can understand.

What do ICS files do?

ICS files allow you to:

• Share calendar events: Easily send meeting requests, appointments, or events to others.
• Subscribe to calendars: Access and view calendars from websites, organizations, or individuals (e.g., subscribe to your favorite sports team’s schedule).
• Import/export calendar data: Transfer calendar information between different calendar applications.

Where do ICS files come from?

• Calendar Applications: Most calendar applications (like Google Calendar, Outlook Calendar, Apple Calendar) can create and export ICS files.
• Websites and Organizations: Websites often provide ICS files for events, schedules, or deadlines.
• Email Attachments: You might receive ICS files as attachments for meeting invitations.

Are ICS files safe?

Generally, yes. However, like any file, it’s possible for ICS files to be used to distribute malware or spam. Exercise caution when opening ICS files from unknown or untrusted sources.

How to use an ICS file:

• Import into your calendar: Most calendar applications have an “Import” or “Add Calendar” feature where you can select the ICS file.
• Subscribe to a calendar: Some calendars offer a subscription option. You’ll typically see a button or link labeled “Subscribe” or “ICS.” Clicking this will add the calendar to your application.
• Open in a text editor: You can actually open an ICS file in a plain text editor to see the raw calendar data. It’s written in a human-readable format.
