How Long Should Your Daily Quiet Time Really Be?

Scripture never gives you a number, and the habit research says the one you pick matters far less than whether you show up tomorrow.

Quick answer

There is no prescribed length for a daily quiet time anywhere in Scripture. What the habit research does show is that repetition — not session length — is what makes a behaviour automatic. So the practical answer is: pick the shortest window you're confident you can repeat tomorrow, and the day after, and let it grow on its own. For most people starting out, that's somewhere between five and fifteen minutes, not an hour.

Ten minutes? Thirty? The full hour the phrase "sacred hour" seems to quietly demand? Most people asking this aren't really asking about minutes. They're asking whether what they already do counts.

It does. That's unsatisfying on its own, so here's the reasoning.

Scripture never gives you a number

Worth sitting with, because a lot of guilt gets built on an assumption that was never in the text. The Gospels describe Jesus praying early, praying alone, praying through the night before choosing the twelve — but they describe when and where far more often than how long.

Very early in the morning, while it was still dark, Jesus got up, left the house and went off to a solitary place, where he prayed.

— Mark 1:35

No duration. A time of day, a place, and a habit. Luke summarises the same pattern with a word about frequency rather than length:

But Jesus often withdrew to lonely places and prayed.

— Luke 5:16

Often. Not at length. And the one place the New Testament does comment directly on the size of a prayer, it cuts against going long:

And when you pray, do not keep on babbling like pagans, for they think they will be heard because of their many words.

— Matthew 6:7

That isn't a ban on long prayer. But it does dismantle the idea that God is running a stopwatch, and that more minutes buy more of His attention.

What the habit research actually says

Here's where it gets useful. The most-cited study is Phillippa Lally's 2010 work at UCL: 96 volunteers picked a daily behaviour and repeated it in the same context — "after breakfast," that kind of cue — for twelve weeks. The headline people quote is 66 days to automaticity. The part they skip is the range: 18 to 254 days. A 2024 systematic review of health-behaviour habit formation found the same messy picture, with individual times running anywhere from 4 to 335 days.

The consistent finding across this literature isn't a magic duration. It's that frequency of repetition drives automaticity, not the length or intensity of any single session. A five-minute practice repeated daily is doing the thing that builds the habit. A forty-minute session twice a month is an event — and events don't become automatic.

Which reframes the question. "How long should my quiet time be?" is a worse question than "how short can it be and still be worth doing?" — because the second one gets you to day sixty.

A rough map of the options

LengthWhat it's genuinely good forWhere it falls apart
2–5 minStarting from zero, brutal seasons, restarting after a lapseRarely enough room to sit with a passage rather than skim it
10–15 minThe realistic daily default — a short reading, a prayer, a pauseNeeds an actual protected window or it gets eaten
20–30 minStudy, journalling, praying through a listHard to sustain daily alongside young kids or shift work
45–60+ minSabbath mornings, retreats, specific seasons of seekingFails as a daily target for most people — and failing it breeds guilt

Notice that nothing in that table is wrong. The failure mode isn't picking the short one. It's picking the long one, missing it four days running, and concluding you're bad at this.

How to pick your number

  1. Start at the length you'd still do on your worst day. Not your best day — your worst. A tired Tuesday with a bad night behind you. That's your real baseline; everything above it is a bonus.
  2. Fix the time before you fix the length. A ten-minute window at 6:40 every morning beats "twenty minutes, sometime," because the second one needs a fresh decision daily and the first one doesn't.
  3. Set a floor, not a target. "At least five minutes" is a promise you can keep. "Thirty minutes" is a target you'll miss and then quietly abandon.
  4. Let it grow instead of scheduling the growth. Most people find the session runs long on its own once it stops feeling like a chore — and a distracted twelve minutes still counts on the days it doesn't.

When longer genuinely is the right call

None of this argues for permanently short. Grief, a big decision, a stretch where God feels distant — there are seasons where sitting a long while is exactly the thing.

The distinction is between your daily floor and your occasional depth. Keep the floor low enough to survive a bad week, and let the long sessions happen when they happen without turning them into a new standard you have to defend.

Protect the window, not the word count

Sacred Hour blocks distracting apps during your quiet time so the length you picked is the length you actually get.

Common questions

Is a five-minute quiet time long enough to count?

Yes. There's no scriptural minimum, and the habit research is clear that repeating a short practice daily does more for automaticity than an occasional long one. Five minutes every day for a month is thirty separate returns to Scripture and prayer. A single forty-minute session is one.

Should I read the Bible or pray if I only have ten minutes?

Both, briefly, usually beats picking one — a short passage gives the prayer something to respond to. Try five or six minutes reading and the rest praying, rather than cramming a full study session into the slot and rushing it.

How long before this stops feeling like effort?

Longer than the internet suggests. The often-quoted 66-day average came with a range of roughly 18 to 254 days in the original study, and later reviews found an even wider spread. The front end is supposed to feel effortful — that isn't a sign you're doing it wrong.

Does it matter what time of day I do it?

The time matters more than the duration, mostly because a fixed slot removes a daily decision. Mornings work well because fewer things have gone wrong yet. If your mornings are genuinely chaotic, a protected evening window you actually keep beats a heroic 5am plan you abandon in a week.

What to do now

Pick the smallest length you're sure you'd keep on a bad day, attach it to something that already happens — after the coffee, before the commute, once the kids are down — and protect that window for two weeks without changing the number. Then look at whether it's still short. Usually it won't be, and you won't have had to decide that on purpose.
