About the Life in Seconds

You have never seen your life measured like this. Enter your birthday and the tool counts the seconds you have been alive, then converts them into heartbeats, breaths, blinks, meals, full moons and trips around the Sun. It also finds your next billion-second birthday: one billion seconds is about 31.7 years, so most people celebrate their first at 31 and their second at 63 without ever knowing.

The numbers update live in your browser using standard averages: a resting heart rate of about 70 beats per minute, 16 breaths per minute, 15 blinks per waking minute and eight hours of sleep a night. Earth travels roughly 940 million kilometres around the Sun each year, so your cosmic mileage is included too.

Share your seconds with friends, or use the milestone table to plan a very unusual party.

  1. Enter your date of birth (and time, if you know it, for extra precision).

  3. Check the milestone table for your next billion-second birthday.

Frequently asked questions

How many seconds are in a year?

A normal year has 31,536,000 seconds; a leap year has 31,622,400. Using the average year of 365.25 days, that is 31,557,600 seconds.

When is my billion-second birthday?

One billion seconds after birth, which is 31 years, 8 months and about 2 weeks later. Two billion seconds arrives at about 63 years and 5 months.

How many times does a heart beat in a lifetime?

At 70 beats per minute a heart beats about 36.8 million times a year and roughly 2.5 to 3 billion times over an 80-year life.

Are the averages accurate for me?

They are typical adult values. Athletes may have resting heart rates near 50; children breathe faster. The tool is for perspective rather than medical precision.
