Importing an iCalendar file to Google Calendar manually is a straightforward yet slightly technical process. First, open Google Calendar in your browser, click on the gear icon, and select "Settings." Navigate to the "Import & Export” section, click "Import,” and then upload your .ics file by selecting the calendar where you want to import the events. Although this process is simple, it comes with challenges such as unsupported calendar formats, incorrect time zone mapping, or large file size errors, which can lead to failed or partial imports. Moreover, users with multiple calendar entries or recurring events may find it time-consuming and prone to errors. 

To avoid these issues and simplify the task, using a specialized tool like the Cigati ICS Converter Tool is highly recommended. This professional utility enables users to convert ICS files into formats compatible with Google Calendar, while also offering features like batch conversion, selective date filtering, and time zone management. It ensures that all events, including recurring ones, are accurately preserved during import. With its intuitive interface, even non-technical users can efficiently manage and import their iCalendar data into Google Calendar without hassle. This makes the entire process faster, safer, and more reliable.
