Assuming these were live trees, in my area, oak takes up to a yr to dry out. Cherry 4-6 months. Not sure how the humidity in your area would effect that.
I'm used to allowing a year for seasoning. It helps to dry faster if it's already cut to length and split.
I still have a big bunch of maple from a tree my neighbor removed, almost a year ago. I've tried it a few times and it's mellowing with age. It's losing the harshness of flavor that it had with less seasoning time.
I bought and use a moisture meter to check wood moisture. Mine is from Harbor Freight. It was cheap, but seems to give accurate readings. I shoot for wood under 15% moisture content. The duration time of curing doesn't matter, as there is a large amount of variation between pieces. It's how dry the wood actually is. Short small pieces dry faster than long larger pieces. At a minimum, split the wood to expose the center, especially if the bark is still on. A year of curing should work for most pieces less than 6" in diameter if the wood is kept out of the rain and with decent air circulation.
I have a wood crib that I dry mine in. The cold dry winter air here will dry it out pretty quickly. I buy a cord that's quarter split in fall put it in the crib for the winter and I can use it the following summer.
