My schedule is really weird. Because I work in America for a company in Scandinavia there is a pretty wide time difference. When I first started they asked if I could be "at work" around 8 or 9 my time, which is very reasonable considering that is 2 or 3 their time. I often volunteer to wake up early when there's something important that's going to happen, and I often work late into the night if I'm trying to get something accomplished, but it's all of my own doing - they never ask me to, or tell me that I have to, and I've actually been politely asked to go to bed before.
On normal working days, though, I wake up naturally around 6, go through my normal routine, and am "at work" by 7-8 anyway. And then I work until around 1 or 2 at which point I take a nap for an hour or so, and then I get back to work until I've finished all my major tasks for that day which is typically 4 or 5. After that, I'm free to do whatever I want, and I try to get to bed by 11 so that I can be sure to wake up the next day fully rested (this is mostly out of respect for my employer rather than out of a sense of habit or of good health).
I do what is best described as marketing automation. For instance setting up campaigns that will send personalized content messages to client customers (think the offers that you receive from a company such a Bestbuy). So there's a lot of planning and testing involved before the campaigns are executed.
Then there's other things like designing some business processes and, occasionally, editing some HTML here and there.
