A quarter of a million hours
Your age in hours grows by 24 every day and passes 100,000 at about 11 years and 5 months old. A 30-year-old has lived about 263,000 hours; a 50-year-old about 438,000. Minutes are 60 times more again, which is why they make a good share card.
How many of those hours were asleep
At 8 hours a night, a third of your life so far has been sleep. Babies sleep 12 to 16 hours a day and teenagers 8 to 10, so for most people the true share is a little higher. The CDC recommends at least 7 hours for adults. Move the sleep setting to see your own split.
| Age | Hours alive | Asleep at 8 h/night | Awake |
|---|---|---|---|
| 10 | about 87,700 | about 29,200 | about 58,400 |
| 30 | about 263,000 | about 87,700 | about 175,300 |
| 50 | about 438,300 | about 146,100 | about 292,200 |
Your hours, priced
If your hours feel abstract, put a price on the ones you trade for money. The real hourly rate calculator shows what each working hour pays once your commute and work costs are counted, and the work hours calculator adds up the hours in a week.
How we count
We multiply whole days alive by 24, so we do not need your birth time and the number changes once a day. If you know when you were born, add the hours since that time of day yourself.
How we calculate
Hours = whole days since birth × 24. Minutes = hours × 60. Asleep ≈ hours × (sleep hours per day ÷ 24).
- Counts whole days, so it does not need your birth time.
- Sleep defaults to 8 hours a day; adults need 7 or more per the CDC, children more. Change it.
