Google Calendar – Duplicate the entire calendar from one year to the next

I have a calendar of events for three months in 2018. All those events will take place in 2019 during the same three months. Is there any way to duplicate the complete 2018 list in 2019 so you do not have to do them one by one?

Extra points –
The events take place on the same RELATIVE DAYS, but not on the same DATES. If there is a way to duplicate events using something like "THIRD MONDAY JUNE" instead of "JUNE 21", that would be even better. Time doubling each event one year in the future.

Ideally, I would like to be able to do this without having to edit each of the existing calendar entries.
