I tend to rise early. Generally I’m in bed by 9:15 pm but may read in bed until about 10 pm, +/- 30 min depending on how tired I am, or how good the book is. Some days if I’m really tired I’ll read Compline in bed at around 9 pm. Whether I say Compline in bed or in my oratory, I will read a chapter of the Rule of St. Benedict plus commentary after Compline, then whatever book I’m reading (a book about the Highland Clearances at the moment, following a vacation in Scotland; I almost never read fiction).
I set the alarm for 5:45 am, generally hit snooze once, then am up at 5:55. I put the hot water on the boil for my wife’s tea, feed the cats, then pray Vigils in my oratory starting at 6 am. By the time my wife is up at around 7:30, her breakfast and tea are on the table and I’m praying Lauds. I usually have breakfast before she does, between 7 and 7:30, while reading my newspaper online. She’s a late riser, if left to her own devices she’d be up at 9 but she has to work so forces herself up at 7:30 or so. If I’ve been up late the night before for whatever reason (jet lag from travel, choir rehearsal, night out with my wife, etc.), I may sleep in a bit the next day. I don’t recall though, when I’ve slept past 7:30 in recent years.
On Sundays I usually get up an hour later, at 7 or a bit later. My little luxury
I used to have a awful commute for a few years (100 km each way each day), and would rise at 4 am to be on the road at 5 in order to beat the traffic into the city. But I can no longer get up that early on a regular basis. I do occasionally rise at 5 if I have something going on and need to be out the door early.
I don’t think the Church has an official teaching on this unless you’re a monk/religious bound to choir and have to be up for Vigils, which can be as early as 11 pm for Carthusians and as late as 5:30-6 am for Benedictines.
