No. It requires some planning. Every species of wood has a different drying time, and it is highly dependent on several conditions, most notably the size of the wood splits and the ambient weather conditions. If you were to separate rounds from a single tree into two separate experiments, taking every other piece from the tree and putting it in alternate piles, you could obtain radically different results just from how you prepared that wood for drying. One pile, ideally, would be split to "normal" firewood size (I consider that anything that can be easily picked up by the end with one hand), stacked up off the ground in a sunny location, top covered, and allowed to dry for three years while exposed to wind and sun. The other pile, for sake of comparison, could be simply thrown into a pile, as rounds, just inside the edge of the woods, covered with a big tarp and left to sit, untouched for three years. Which one would you think would be likely to be acceptable firewood in that space of time? I believe that the pile of rounds covered by the tarp would be partially rotten and not have lost much of its' original moisture. The other stack would be ready for anyone to burn.
Those conditions could be taken to even more extremes. I know of people who stack split wood in greenhouses or solar kilns, with fans and even dehumidifiers. I would imagine that under those conditions, even carefully sized oak splits would be ready for the woodstove in less than a year. Still others, drag dead trees up to their porch with the tractor and burn the chunks they cut within hours.
If you do not have the resources to harvest your own firewood, plan ahead. Figure out how much you need for a year's time, and then buy three times that amount to start. Find a place to stack it, cover the top of the stack, and let it dry. Every year after that, buy another year's worth of wood, stack and cover. Burn the pile you stacked three years ago. Repeat indefinitely. For the first two years only, following that plan, you will have to find a source of seasoned wood for the first year, and you will have moderate success with the prior year's stack for the second year. Build a wood shed and use it.
