A question about villagers moving

[lucylucy27]

If a villager says “I’m leaving on the 16th”, does that mean they’ll be gone by the 16th, or they’ll be in boxes on the 16th?

I am almost positive that the date they give you is the date they will be in boxes. They will be gone the next day.

I'm pretty sure this is correct.
