Depending on how cooked you like your hard boiled eggs, the eggs should be done perfectly in 10-12 minutes. That said, depending on your altitude, the shape of the pan, the size of the eggs, the ratio of water to eggs, it can take a few minutes more.
Boiling an egg takes a while. Once the water starts to boil and the eggs are inside the boiling water, let the eggs boil for about 5 to 10 minutes. Careful, if they boil for too long, they might crack. Alternatively, bring the eggs and water to a boil. Remove from the heat, cover, and let sit for 25 minutes.
