How long do ducks take to hatch??

Hello, I really wanna know how long it takes for mallard duck eggs to hatch? Everywhere I read says a few days so I am wondering if anyone on here hatched them and knows how long they take from their experience

28 days of incubation give or take and 12-48 hours after pipping you should have a duckling!
