Yep, 3 months minimum for most credits, 12 months for EAp2/EAc1. Also, just to be clear, the date of registration doesn't really have any bearing on the performance period.
It's a good idea to register early because that's when you get access to LEED Online and various other tools, but if you wanted to (not advised) you could register just prior to submitting your application.
