Frequently Asked Questions
Why is the Google time in UTC?
Google Calendar TEMPLATE dates use compact UTC (YYYYMMDDTHHMMSSZ). Your local start and end are converted with the JavaScript Date in this tab so the event lands at the same instant worldwide.
How do all-day events work?
All-day events use DATE values. Google and ICS treat DTEND as exclusive, so a two-day event on Aug 20–21 is encoded as 20260820/20260822. Yahoo uses inclusive start and end dates.
Will Apple Calendar open these links?
Apple Calendar does not use Google or Outlook web URLs. Download the ICS file and open it, or attach it to an email. The ICS works in Apple Calendar, Outlook desktop, and Thunderbird.
Does my event leave the browser?
No. Links and the ICS file are built in JavaScript on your device. Opening a Google or Outlook URL only sends the query string to that provider after you click, not to this site.
