Concrete Driveway

We have an asphalt driveway now and we think about replacing it with a concrete one.

My question is about curing process/time.

We have 3 cars (SUVs) and the garage that can fit just one vehicle, so our 2 SUVs are on the driveway all the time (summer and winter).

If we decide to go with a concrete driveway then how long will it take until we can park our two cars (each about 2 tons) back on the driveway again?

I can rephrase this question like this: for how long we will need to park our two cars on the street and wait until concrete cured enough to bring them back to driveway?

Thanks,

Mark
