Your life, counted in seconds
Enter your birthday to see roughly how many seconds are ahead of you, from public life tables. It's an average, not a prediction: a nudge to spend today on what matters.

If thinking about time or death feels heavy right now, you’re not alone. In the US, call or text 988 (Suicide & Crisis Lifeline). Elsewhere, find a free, confidential helpline at findahelpline.com.
How it works
Life tables record, for each age, how many more years people of that age live on average. LifeClock looks up your exact age in the newest table for your country and sex, adds that many years to today, and counts the seconds down to that date. For the United States it uses the Social Security Administration's 2023 period life table (from the 2026 Trustees Report); for 184 other countries and the world it uses the World Health Organization's 2023 life tables.
The worldwide average at birth is 73.3 years. The older you are, the further the average reaches, because you've already lived through the risks of earlier years.

Why count seconds?
A big number in seconds makes time feel concrete in a way “decades” doesn't. Some people keep it on a second screen in desk mode as a nudge to skip what doesn't matter. If a countdown isn't for you, switch to time lived: it counts up instead.
