Aging a finished cigar is not the same as aging bales of leaf at the factory. The factory already fermented and rested the tobacco. What you do in a humidor is slower: moisture equalizes, sharp edges round off, and — if the box is stable — the smoke can get smoother. If the box is a swamp, you get mold.
Time is not a recipe. Some cigars are packed to smoke now. Some houses, Padrón among them, already age the leaf for years before it is rolled. Putting those in a cabinet for another year is a preference, not a correction of the factory.
Keep relative humidity in a commonly cited range, give them air, and do not invent a calendar. See humidors.
