Hi Joseph,
Thanks for reaching out!
Users can currently select the year in the Date field of the Tribe Events Bar (see screenshot), but to add new links to change the year, you would need to customize the templates for the views you want to add them to by following these instructions.
We have actually started working on displaying multi-day events as one event that spans across days in month view! If you’d like to stay up to date on progress for this, please cast your vote for this feature request here – we post progress updates as we have them. I took a look at the site you linked to, but it is actually using a different calendar platform (not The Events Calendar).
For now, our themer’s guide is the place to start if you’d like to make this customization yourself, or we also have a list of recommended developers you could contact if you’d like to have the code done for you.
We are limited in the amount of support that we can provide for customizations, but if you get stuck or have any questions, please let me know and I’ll be happy to point you in the right direction!
Thanks,
Jennifer
