any set date for whipes?

As The titel say. Is there any set dates when a whipe Will occure? Or how can we know when they Will whipe next time?

When The game is starting to be finished. Will whipes still happen then?

The game wipes every 4 weeks on patch day (Thursday). The last wipe was this past Thursday.

As for your second question, I have no idea. That will likely depend on server admins who will wipe when they judge it necessary rather than being forced to do it by an update.

one of their aims is to get servers running well enough that wipes are not required; however, servers may choose to wipe even when this is possible.
