Hi Lucie,
Thanks for reaching out and for your interest in our plugins 🙂
If I’m understanding you correctly and – in essence – you want the calendar to automatically ‘recycle’ events by moving them forward a month, each time a month passes, then no I’m afraid that isn’t supported (though if you like coding, or have access to a developer, this wouldn’t be too hard to build as a further customization).
However, you may be interested in our Events Calendar PRO plugin. This builds on top of our free, core plugin (The Events Calendar) and its flagship feature is its recurring events functionality.
This allows you to create an event and have it repeat every month (or week, or some other interval). If you defined an event starting today and repeating every month for 12 months, for example, it would generate 12 events and add one to each upcoming month.
It’s possible that would suit your needs here; what do you think?
