Frequently Asked Questions
What is an .ics file?
An .ics (iCalendar) file is a universal calendar file format that can be opened by any calendar app — Apple Calendar, Google Calendar, Outlook, Thunderbird, and more.
Do I need a Google or Microsoft account to use the links?
Yes, the links open the web version of each calendar service, so you need to be logged into that service in your browser.
Can I use this for recurring events?
Currently this tool generates single-instance events. For recurring events, download the .ics file and import it into your calendar app where you can set recurrence.
How accurate is this calendar link generator tool?
All processing runs entirely in your browser using verified algorithms. Results are computed with full double-precision — no server-side rounding or data transmission occurs.
