About CorrectICS

CorrectICS helps you validate and automatically fix iCalendar (.ics) files so they import cleanly into real clients like Google Calendar, Microsoft Outlook, Apple Calendar, and Teams.

Why We Built It

Calendar files are deceptively tricky: small formatting differences and edge cases can cause broken imports, missing time zones, or silently dropped events. CorrectICS exists to make .ics interoperability predictable, with validation rules and autofixes tuned to how major calendar apps behave in practice.

Ownership

CorrectICS is owned and operated by Gulfhawk LLC, based in Delaware, USA.
