On weekdays, DD8 begins her bedtime routine at 9:30pm, with lights-out usually around 10:00pm (DW and I don't regulate, as we do not possess the power over space and time to control when DD is ready to sleep), and gets up at 7:30am. We've been noticing behavior that signals sleep deprivation issues in the last week or so, so we've implemented some nighttime routine changes to get her in bed quicker, and the next step will be a move to 9:00pm if that doesn't yield satisfactory results.

On weekends, she gets to stay up to 10:30pm, and gets up whenever she likes... usually 8:30-ish.
