Hi Marcel,
to answer your question, it all depends on when your next cycle begins. In fact, PMI allows you to earn PDUs in the current cycle and apply them to the next cycle; however, this only applies to the last 12 months of your certification cycle.
So, if you are already in the third year of your certification cycle and you already earned 60 PDUs, a portion of the next 40 PDUs you expect to get in a couple of weeks will roll over the next 3-year cycle; specifically, my understanding is 20 PDUs (max), based on the CCR Handbook .
The reference point for the 3-year certification cycle is the date you passed your PMP exam. Also, keep in mind that—even if you renew now (i.e., before the end of your certification cycle)—the certification renewal date will remain 3 years from the original renewal date.
