Watering new concrete driveway.

Last week a cement mason broke up my 80 year old Los Angeles driveway and put in forms. It's about 20 feet long and 12 feet wide on a slight grade. A cement truck filled the forms and he smoothed it out and told me to water it 5 times a day for a week.
I have been, but online I've read cement takes 28 days to cure and it should be watered a few times a day for that period. The weather has been overcast in the low 70s and in the 50s & 60s at night. Was I told correctly about not using the driveway for a month and should I be watering 6 times a day (just hosing it down for 5 minutes) for that 28 days? Any input gratefully accepted!

Yes, he is right.

Concrete cures for up to 90 days... It reaches a good percentage of its maximum psi after 28 days if you keep it wet for at least a week or more. Enough that you can drive on it after that. Not with heavy equipment... But a passenger car, yes.

This graph explains it best.
