How long does a Mercury Decennial last?

In the classical scheme used here, the major period lasts ten years and nine months. It begins when Mercury takes over in the fixed sequence and ends when the next major ruler succeeds it, although the co-ruler changes the finer texture within that span; check the active division for the exact boundary.

Does the co-ruler override Mercury during this period?

No, the co-ruler modifies the expression without replacing Mercury’s main agenda. Communication, study, calculation, and exchange remain central, while {{sub_lord}} shows how those themes are currently delivered; read the major ruler first and the co-ruler second.
