Wherever you live on the Earth's surface starts cooling every night and gets warmed up again the next day. It wouldn't cool any faster if the sun went away, it would just keep cooling at the normal rate until everything was frozen. But I doubt it would take more than a week or two, depending on where you live.

Yeah, but that's with petawatts being blasted on the other side of the earth every second, wouldn't the loss of that make the whole system cool down faster, including the side the sun doesn't touch? I'm thinking it'd be like having food on a hot plate, bottom is very hot, the top is less hot. But if you take the food off the plate the whole thing rapidly goes to room temp. I honestly have no idea, just conjecture tbh.

The only way to get the right answer would involve doing math and knowing enough climatology and geology to even know which math, so I dunno.

Someone posted a link above, claims it'd take about a week to hit 0°C

Cool, I will take a look. Intuitively that seems about right to me. I was just saying the world definitely wouldn't freeze overnight.

Well when temps are already ~ -1°C in your area you tend to freeze a bit quicker
