About BornClock
Know your time. Live it well.
We believe everyone deserves to understand their own timeline — not just in years, months, and days, but in the full cosmic and biological richness of what a human life actually is.
"Know your time. Live it well."
This is what BornClock is built around. Life expectancy, birthday insights, and the science of a longer life — all from your date of birth.
What We Do
BornClock gives you a handful of simple, beautiful tools built around one input: your date of birth. From that single number, you can find out your exact age to the second, how old you are on every planet in the solar system, which celebrities share your birthday, what your zodiac sign and birthstone are, your numerology life path number, and a science-grounded estimate of how long you might live — and what you can do to change it.
Everything runs instantly, in your browser, without requiring an account. The data we need stays on your device. The result you get is yours to keep, share, or explore.
The Science Behind BornClock
The Life Expectancy Calculator — our most complex tool — is built on three independently validated pillars. We don't just hand you a number; we show you every factor that went into it and let you explore what changes.
Pillar 0 — Where You Start
Age-conditional baselines from UN World Population Prospects 2024, specific to your country, age, and sex. The same tables actuaries and governments use.
Pillar 1 — Your Genes
Family longevity adjustments derived from heritability research (Polderman et al., Nature Genetics, 2015). Because your parents' and grandparents' ages tell a story.
Pillar 2 — Your Choices
Twelve modifiable lifestyle factors — from sleep to community bonds — each calibrated from peer-reviewed studies (GBD 2019, Lancet, NEJM). You have more control than you think.
Every source and formula is publicly documented on our How It Works page.
Built in India, Designed for the World
BornClock was started by an independent team in India who wanted to build something both rigorous and accessible — a tool that respects your intelligence, cites its sources, and doesn't treat you as an advertising target.
We support 54 countries with country-specific life expectancy baselines, including detailed data for India (sourced from WHO and the UN). We are deeply aware that longevity research has historically over-represented Western populations, and we are committed to expanding our regional data as better sources become available.
Our tools are used by people who are curious about science, fascinated by space, planning their health, or simply want to know which Bollywood star shares their birthday. We don't think those are different kinds of people. Curiosity is curiosity.
