vivo activ 3 calendar holidays

Have you checked in the default calendar app on your phone?

In apps I only have Google Calendar. In Google there are other accounts, but only 1 has data checked (holidays, events, etc). The weird holidays do not appear on Google Calendar 

In the calendar list in Google Calendar there are calendars far down in the list below all accounts: Holidays and Birthdays

Is Holidays unchecked? 

Both unchecked.

See if you can see anything in Google Calendar online: https://calendar.google.com

None of the unwanted holidays showing there.

Example today.
