Mine go in at about 9.45 - 10pm. It is still quite light then here. There are some evenings I think, I would like to go to bed at about 9.30 and it is then that they seem to decide 10pm is a much better time to go to bed. There is still another month before the longest day and that means lighter evenings with us until about 11pm. It will be interesting to see what time they head off to bed then.
