When does AT&T disconnect internet service when moving it to new location?

So I will be moving from my current place to a new house in a week. The internet at my current location will be disconnected on the 19th, but I won't have internet access at the new place until a technician come over on the 20th. So my question is...I know my disconnect date is the 19th, but what time on the 19th? Will AT&T shut off my internet on the 19th at 12:01am or is it 11:59pm? Or do they do that during the day? I'm moving to a new house with fiber connection, which my current place does not have (if that matters).

I'll still be staying at the current place on the night of the 19th, so was hoping I'd still have internet up for me to get some work done during the night. I posted the same question on another section, wasn't sure which forum section this ought to go into...
