Miss...
The standard in my time was to wait a month before you made plans, just to see if things stuck. But if you hadn't made plans before six months, you were just prolonging it for fear of being together.
As a lady, it's your job to start the planning. Usually it was up to the lady's family to set the date, though as things are here, I'm supposing that you should talk that out with your fiance, see what date sounds the best for both of you.
