How Many Hours a Day Should You Spend Learning a Language?

“How many hours a day” is really a question about two numbers: how many total hours your goal takes, and how many days you can keep showing up. Multiply them and you get a date. This post does the multiplication for a few common goals, then looks at what the evidence says about splitting time up.

If you want the softer guide to choosing a daily target you'll actually stick to, see daily study time recommendations. This one is the math.

Start with the total

Three reference points, all for a native English speaker:

• Spanish to a rough B1: about 345 hours, half of FSI's 690 class hours. That's the figure our B1 guide uses for Spanish and French, just under the 350–400 hours Cambridge English gives for English B1, so treat it as the optimistic end.
• Spanish to professional working proficiency: 690 class hours, the U.S. Foreign Service Institute's published figure (roughly upper B2 to low C1).
• Japanese to the same level: 2,200 class hours, FSI Category IV, same as Arabic, Korean and Mandarin.

Other languages fall in between; the FSI language list has all of them.

What each daily amount adds up to

Two things jump out. First, 15 minutes a day is real progress on an app streak but a very long road to a working level. Second, the difference between 30 minutes and an hour is the difference between finishing a goal in two years or one. If you can find the extra half hour, it's the single biggest lever you have.

These are class-hour equivalents. FSI students also do about 17 hours of self-study a week on top of 23 hours of class, so “690 hours” in their setting means considerably more total effort. Treat the table as a best case for focused study.

Plug in your own numbers

Is more per day always better?

Up to a point. FSI's own full-time students study about 40 hours a week, so several hours a day is clearly workable with good teaching and structure. But for self-learners, two things limit the benefit of very long days:

• Spacing beats cramming. A large 2006 meta-analysis by Cepeda and colleagues found that spreading study across more sessions reliably improves long-term retention compared with massing the same time together. Thirty minutes every day beats three and a half hours on Sunday. More in how far apart to space study sessions.
• Attention runs out. Three hours of active study is very different from three hours of a show in the background. If long sessions turn passive, count them honestly, or split them up.

A practical way to choose

1. Pick your goal and find its total hours above.
2. Pick the date you want, and divide. That's your required daily pace.
3. Compare it with what you've actually logged over the last two weeks.
4. If the two don't match, move the date or the goal, not just the hope.

Most people find their sustainable number is lower than they'd like and higher than they fear. Mixing passive time (listening on a commute, shows in the language) with focused study helps the total, as long as you track the two separately; see active vs passive learning.

For what each level actually means, see CEFR levels explained. For the far end of the scale, how many hours to reach C2.

FAQ

How many hours a day should I study a language?

As many as you can keep up every day for months. For most working adults that is 30–60 minutes. At an hour a day, a rough B1 in Spanish (about 345 hours) takes about a year; at 30 minutes, about two.

Is 1 hour a day enough to learn a language?

Yes, for steady progress. An hour a day is 365 hours a year, roughly the distance from zero to B1 in Spanish or French for an English speaker. Harder languages like Japanese take several times longer at the same pace.

Is it better to study every day or in longer sessions?

Research on distributed practice consistently finds that spreading the same total time over more sessions improves long-term retention compared with cramming it into fewer, longer sessions.
