Years ahead
We use remaining life expectancy, written e(x): the average number of years still ahead for people who have already reached your age in your country. It comes from the United Nations World Population Prospects 2024 life tables for 2026, medium variant, by single year of age. Subtracting your age from life expectancy at birth undercounts, because having reached your age already improves the odds.
An average hides a wide spread, so the page leads with the age half of people your age live past, and gives your free hours as a range for the middle half of people like you: the hours you would have if you lived as long as the lower and the upper quartile. By default today’s death rates are held fixed. The “keep falling” option follows the UN’s projected rates year by year instead, which usually adds a few years.
Healthy years are rough: they apply the WHO 2021 ratio of healthy life expectancy to life expectancy, at birth and at 60, to your remaining years.
Time that is yours
Waking hours, minus work and commuting until the age you stop working, minus daily upkeep for the rest of your life. A work year is 52 weeks minus your time off. You decide which parts of your day count as obligations.
People
Shared years are the expected time you are both alive, treating your chances as independent, from each person’s own life table.
Comparisons run the same model for the other person, with their own country, age and week.
Conversions
- Reading: adults read English silently at about 238 words a minute for nonfiction and 260 for fiction (Brysbaert, 2019, a meta-analysis of 190 studies). A typical novel runs about 80,000 words.
- Languages: about 500 to 600 guided learning hours from beginner to B2 (Cambridge English). A time equivalence, not a promise.
- Trips count 8 free hours a day. Movies are 2 hours, TV seasons 8.
- Conversions in a row are alternatives. An hour can only be spent once.
