My questions are as follows (mostly concerning Barovia/Vallaki)

* When do herbs start appearing, right on the first of month three (March)?

* When do herbs stop appearing, right on the first of month eleven (December)?

* Whats the time frame for the ferry, month three (March) to month eleven (November)?

Herbs start spawning on month 3, however if the temperature is low enough, snow will still spawn. The same goes for fall herbs, I've seen snow happen as early as month 10. Herbs stop spawning on month 12. The ferry is only unavailable during the winter.
