I understand that it's basically free from 9-5:59, but in the case of Sunday, If I talk from 9pm to 2am, is that still free? I'm just confused about Sundays and I hope I just didn't get charged.

So my sunday call from 12am to 2am, for example, is still free? I read that Sunday's minutes end at 11:59, but I don't understand that when weekdays end at 5:59. Maybe I'm thinking too much into it.
