Question regarding firewood drying time
Depends on the local climate, how you dry it, whether you split it, and what you are burning it in.

Pulling a piece from the pile, splitting it, and using a moisture meter on the freshly-split face is a typical approach of careful woodburners checking on moisture content. Folks that know what they are doing and who use gasifying woodburners tend to be picky about moisture content as it can negatively impact the clean and efficient burn they are looking for.

Unsplit dries slower than split. Unroofed dries slower than roofed. Tarped over dries slowly if at all (no air movement.) Actively solar heated (with vents) dries faster than not. Stuff dried in a climate with a low dew point dries faster than stuff dried in a climate with a high dew point...

In many places, 1 year is not really enough with typical firewood storage practices. In other places or with other practices, it can be sufficient.
