A lot depends on where you live. In Boston which is fairly northernly by US standards and very far east in a time zone, for example, staying on Eastern Standard Time year round would mean it's sunrise at about 4AM on the summer solstice and it gets dark at 8:30pm rather than 9:30pm like today.

Now, these days, I have a lot of schedule flexibility and at least for activities I'm doing on my own I could just get up earlier in the summer. I'll be a bit out of sync with business schedules but I could largely do it.
