The 8-8-8 rule is a myth: how much free time you actually have

The 8-8-8 rule says your day is eight hours of sleep, eight of work and eight of free time. In my tracked data it did not hold up: commuting, meals, routines and errands took almost four hours of every weekday, so my real free time was far less than eight hours. This is the maths, from 188 weekdays I tracked in 2025.
Where did the 24 hours of my weekdays go?
My average tracked weekday had 9 hours 9 minutes of sleep, 6 hours of work, 3 hours 58 minutes of overhead and 4 hours 53 minutes of everything else. That “everything else” is the only part I could call free time. It was never eight hours.
A note about the work number: I’m a contractor paid by the hour and I try to log only actually productive time as work. That is why my work average is 6 hours and not 8. I use an 8-hour job in the bottom bar so the comparison is fair.
What counts as overhead?
Overhead is everything you have to do to keep the day running but would not call free time. Here is mine, per average weekday:
| Activity | Time per weekday |
|---|---|
| Moving (commute and transport) | 1:36 |
| Eating | 0:46 |
| Morning routine | 0:42 |
| Errands | 0:14 |
| Showering | 0:14 |
| Evening routine | 0:11 |
| Eating out | 0:08 |
| Cooking and food prep | 0:07 |
| Total | 3:58 |
None of these is wasted time, but they all eat into the free third of the day. I left laundry, cleaning and packing out of this table, and they add a bit more on top.
How much free time do you really have with a full-time job?
If you sleep 8 hours, work 8 hours and have the same overhead as me, you are left with about 4 hours of free time, not eight. And that is before social plans, relationships, hobbies and relaxing all compete for the same four hours.
Free time was bigger on weekends: social time went from 1 hour 7 minutes to 2 hours 24 minutes a day, and my four side projects from 5 minutes to 1 hour 38 minutes. If you want the full comparison, see my full 2025 time data.
Why does this matter?
Because unrealistic expectations feel like personal failure. If you believe you have eight free hours, then “I did not work on my hobby” feels like laziness. If you know you have about four, and that some of them must go to rest, the same evening looks reasonable. Being alive takes a lot of overhead, and that is okay.
Plan with real numbers. If you want more free time, look at the overhead first: the commute, the long mornings, the errands you could batch.
How do you find your own number?
Track one typical week and add up four things: sleep, work, overhead and everything else. A personal time audit does exactly this. Use a spreadsheet, or a timer app if you want it to be effortless.
I make Nanominute for this, so I’m biased. I built it for my own pain point, I use it every day, and there are no ads. I never sell your time tracking data. You can try it free for 2 weeks, or start with the free spreadsheet template. Either way, measure once. The number may surprise you, and it may take some guilt off your plate.

Frequently asked questions
What is the 8-8-8 rule?
The 8-8-8 rule says a day splits into 8 hours of sleep, 8 hours of work and 8 hours of free time. It is a neat idea, but it leaves out time spent commuting, eating, getting ready and running errands.
How much free time does the average person really have?
It varies by person, so measure yours. In my tracked weekdays in 2025, free time was about 4 hours 53 minutes, and about 4 hours if I applied my overhead to a standard 8-hour job.
What counts as overhead?
In my data: commuting, eating and cooking, morning and evening routines, showering and errands. Together they were 3 hours 58 minutes on an average weekday.
How do I measure my own free time?
Track a typical week with a timer app or a spreadsheet and add up sleep, work and overhead. Whatever remains is your real free time. A one-week personal time audit is enough.
