How do BCE and CE dates affect millennia calculations?

The unit size stays the same. A millennium is always 1,000 years. The main point is how you count across the BCE to CE boundary. There is no year 0 in the BCE/CE system, so counts that cross that boundary need care.

Does the start of a millennium depend on the calendar?

Yes, it can. In the Gregorian calendar, counting that starts at year 1 means the 3rd millennium begins in 2001, not 2000. In casual use, many people treat 2000 as the start. Both show up, so the context matters.
