How long can I ride on the spare tire donut?

My tire got a flat tire on my vehicle listed above F Sport AWD. The puncture is on the side wall which means the tire cannot be repaired. Triple A came out and removed the flat tire and replaced it with the donut in the trunk of my car. Called Les Schwab and they informed me that they couldn’t order the tire until Monday because it has to be ordered directly from the manufacturer. In the meantime, I am asking how long can I ride on the donut that came with my brand-new car without causing any damage?
