It seems like there's some unclear or nonsensical text being presented. However, based on the first part of your statement ("Yes, but no date has been decided yet"), it sounds like you're saying that a specific event or decision doesn't have a planned date yet.

If I had to ask for clarification or try and help with this conversation, I'd say something like:

"You mentioned an event without giving a specific date. Is there anything else you'd like to talk about regarding this event? Or perhaps we could discuss the importance of setting dates for such events?"

But keep in mind that I might be misinterpreting the context completely because of the unclear text after the first part of your statement.
