Regarding the definition of weeknight unlimited calling in T-mobile family plan,?

[JohnL]

if I began a call from say 8:45pm and ended at 9:15pm during the week, how many minutes am I going to be charged? Am I going to be charged 30 minutes or 15 minutes of airtime?

15. Likewise, if you start a call at 5:45 AM and talk until 6:15 AM, you'll be billed for 15 minutes.

Unless you're roaming off of an other carrier's towers at the time, it won't use up any of your minutes to talk between 9pm-6am if you're talking to someone with a US phone number.

only 15 honey. They will charge you up till 9pm. However call them and double check. and monitor your bill!
