How long after asking to move out do villagers leave?

[Neorago]

My dear Kitt asked to move and I told her to spread her wings and fly lol. I was just wondering how fast the process of them packing up and moving away is in comparison to New Leaf. thanks in advance

they start packing a day after you tell them to move

And then are out the day after that
