Hi there, Tamara! Thanks for getting in touch and welcome to the forums. We hope you’ve been enjoying the plugins so far. 🙂
Good question. Recurring events follow daily, weekly and monthly patterns. There is a custom option that allows you to create more complex patterns (e.g. weekly every three weeks), however, there is currently no way to create a pattern based off a specific date in the month (e.g. third Wednesday of each month).
We’ve started work on a more free-form way to create recurring patterns that I think will do exactly what you’re looking for. Unfortunately, there isn’t a set timeframe for when it will be released.
Sorry I don’t have more of a concrete solution for you here, but does this at least help answer your question? Please let me know.
Cheers!
Geoff
