What time should you actually wake up?

The internet has an answer to this and the answer is 5am, which is a slogan rather than a time. The useful answer is arithmetic, and it takes about two minutes to do.

Start from the end of the day, not the beginning

Almost everybody picks a wake time first, because it feels like the decision. It is the wrong end. The wake time is the *output* of two things you do not fully control: when you have to be somewhere, and when you can actually be asleep.

So do it in this order.

1. When does the day genuinely start? The first fixed thing — leaving the house, the first meeting, the school run. Be honest rather than optimistic.
2. Subtract what the morning actually takes. Not the theoretical minimum. Time yourself for three days: most people are twenty minutes out, in the wrong direction.
3. Add whatever the morning is for. If the whole point of getting up earlier is to train, write, or study, that block goes in here — this is the number that makes the wake time earlier, and it should be the only thing that does.
4. That is your wake time. Write it down.
5. Now subtract your sleep from it, and look hard at the bedtime that comes out. If that bedtime is not plausible on an ordinary Tuesday, the wake time is not real and you have not found it yet.

The step everybody skips

Step five is where most early-rising plans die, and they die silently. You can decide to wake at 5:30. You cannot decide to fall asleep at 9:45 if you are not tired at 9:45, and you cannot decide to need less sleep. What you get instead is a fortnight of running short, then a weekend that undoes it, then a conclusion that you are "not a morning person".

If the bedtime that falls out is not realistic, you have two honest options and no third one: move the wake time later, or do the work of moving the bedtime earlier — in fifteen-minute steps over a couple of weeks, not in one night.

How much sleep to plan for

Adults generally land somewhere in the seven-to-nine range, and where you land inside it is individual and not really negotiable by wanting. Plan for what you need on an ordinary week rather than what you can survive on, and remember that time in bed is not time asleep — you will not fall asleep the instant the light goes out, so add a margin for that.

The signal that the number is right is not how you feel at 6am, which is unreliable for everybody. It is whether you are functional in the early afternoon without needing to fix it.

Pick one time, and use it on Saturday too

A wake time that moves by two hours at the weekend is a small time-zone change you inflict on yourself every week, and Monday is the jet lag. Holding it steady is worth more than making it earlier.

If a fixed weekend feels impossible, hold it within an hour. The consistency is doing most of the work; the exact number is doing less than you think.

A good test of the time you have chosen: could you keep it on a Wednesday in February with nothing to look forward to? Wake times that only survive a motivated week are not wake times, they are moods.

Then make the number hold

Having the right time is about a third of it. The rest is that the alarm has to survive contact with somebody who has just been woken by it, and the person at 6am does not agree with the arithmetic you did at 9pm.

That is the gap Roosta is built for. You choose the mission at night, while you still agree with the plan, and in the morning there is no snooze and no skip — the alarm stops when the mission is finished. Alarms freeze in the hours before they ring too, so the six-o’clock version of you cannot quietly retime the number the eleven-o’clock version worked out.

For the part after the alarm, see the first ten minutes. If the bedtime end is the problem, how to stop scrolling in bed is the one to read.
