How long after carbs will i come out of ketosis?

Does anyone know roughly how long after a low carb healthy meal i will come out of ketosis? I am having an important night out in 3 week and want to know if i should have a healthy carb dinner the night before and then another the night that i go out. Or would it be enough just to eat a carb dinner that same night?

Thank you :)
