pdq, the Clemson extension service article does state that peak water demand is 5AM-9AM, thus watering before that time is desirable.
One may install timers, if watering in the very early morning hours interferes with your beddy-bye time.

There is greatly lessening demand for lawns in the semiarid and arid areas; many people are changing to xerarch plantings which can be very attractive, and require much less water (with lower water bills).
Several homeowners in my neighborhood have removed much or all of their lawns. Home value is not affected by the change.
