How Much Sleep Have You Had?

How to Play 😴 How Much Sleep Have You Had?

Pick your date of birth and the page works out how much of your life you have spent asleep, based on your average hours per night (slide to adjust from 4 to 12). Since most people sleep around 8 hours, that adds up to roughly a third of your entire life! You will see the total in years, plus the number of days and hours asleep, an estimate of how many dreams you have had, and what percentage of your life it represents. Move the slider to see how a little more or less sleep changes the totals over a lifetime.
