I am trying to get a mobile version of a Google calendar to embed into a mobile website without having to log in. If anybody has gotten this to work before or has any idea how to do it please help.
These days, there are a number of third party apps that make it easy to embed mobile-responsive Google calendars.
Here are a couple of options:
Or, if you'd rather use something open source, FullCalendar is a great solution. They have a calendar list view that works particularly well on mobile. If you wanted the desktop and mobile layouts to be different, you could potentially use a resize observer on the calendar's container to trigger FullCalendar's changeView method. Here is some documentation on how to use FullCalendar's Google Calendar plugin: https://fullcalendar.io/docs/google-calendar
