POTENTIAL FIX:
Open the calendar, click “calendar” at the bottom and turn off “US Holidays” and “Birthdays” calendars (located under the “Other” category in the calendar list). So far it comes up to the current day every time.
Not a perfect fix because those are nesded calendars to a heavy calendar user. However it’s less annoying to have to constantly click on “Today” since some days I need to check the calendar on an hourly basis. Apple we still need a fix that allows to use Holidays and Birthdays and that comes up to Today each time.
Apparently those are not supported on the calendar syncing settings or something.
