Corrected entry: Phases of the moon - when Elliot first goes to the backyard to find ET, the moon phase is either the first or last 1/8. The next night, there is no moon (okay, so maybe it was a different time of evening). But then the next day, when the kids are taking ET to the mountain, the moon is full. The moon never goes from 1/8 lit to full in 2 or 3 days.

Correction: Several days/nights pass between the night Elliot brings E.T. into his room and Halloween (when they take him to the forest), not one. There's the day Elliot fakes being sick and the night the kids show him the map of the solar system, followed by the day Elliot goes to school. The night the agents eavesdrop on Michael and Elliot in the garage suggests the passage of time (first, the agents needed time to bug the neghborhood; second, Michael's concerns about E.T.'s well-being indicates some time has elapsed).
