Also work 3rd shift. I always mow on either my day off or after I wake up.Just finished the first cut of the season. I work 3rd shift so I plan on cutting the grass at 7:30am this summer after I'm done with work. I'm not going to mow on weekends because I don't want to piss the entire neighborhood off, but I don't think starting at 7:30 on a weekday is unreasonable.
And yes I know it's not good for the grass to cut it that early, that's why I keep a razor sharp blade.
