not that I make much noise

...but what are the times thresholds that limit noise in towns?
I've played noisy games until 2am most weekends...and upto midnight most nights.... I assume this could cause issues!???
Also, one of my neighbours is rather loud when communicating with her children when they, seemingly, have been naughty...this is most mornings before 8am and always weekends b4 9am
What's the noise law!?
