How does the Death Clock calculate my death date?

The Death Clock uses Social Security Administration actuarial life tables as a baseline, then adjusts using published hazard ratios from peer-reviewed mortality studies. Lifestyle factors like smoking, exercise, BMI, sleep, diet, and alcohol consumption each modify your baseline life expectancy.

Is my data stored or shared?

No. Your data is processed entirely in your browser. Nothing is sent to any server, stored, or shared. The calculation happens locally on your device and is discarded when you leave the page.

Can I change my estimated death date?

Yes — that's the entire point. Every lifestyle factor in the calculator is modifiable. The results show exactly how many years each factor is costing you and what changes would extend your life.
