@rafalle777 10 on weeknights and 12 on weekends.
Most towns and cities have some type of curfew in place that says people under the age of majority (usually 18) can't be out after a certain time (usually 12am) unless they are accompanied by a responsible adult, they are traveling to or from work, or it's an emergency. No one realizes this is the case, but you can probably look it up for your area and find out...... What it's really for, is to keep people from wandering around town in the middle of the night or hanging out in public places in the dark to prevent crime. It'd be weird for anyone to be like, pulled over and get in trouble just for being out too late. But it says what it says and I used the city curfew to validate both my daughters curfew being midnight. They occasionally asked to be out later and I usually let them.
I also still remind them, even tho they are older, that while they live here, I need them to have a reasonable schedule because I have to sleep and if they are out all night, it's hard for me to do that and then get up early.
I like to give them logical reasons for the handful of rules I have kept in place beyond "because you're too young" or "because I said so". It has been fairly successful in my opinion.
The flip side of that is that they can bring their friends over any time they want and then everyone is safe somewhere and not out roaming the roads late at night.
As a result, I have a house full of teenagers all the time and I'm ok with that.
