FAQ
How are heartbeats and breaths estimated?
Using average resting rates - 70 heartbeats per minute and 16 breaths per minute - multiplied by the total minutes you've been alive. Individual rates vary quite a bit in real life.
How is "full moons seen" calculated?
By dividing your total days lived by the average lunar cycle length of about 29.53 days - a fun approximation, not an exact astronomical count.
Is this scientifically precise?
No - it's meant to be a fun, illustrative estimate using average figures, not a medically or astronomically precise calculation.
Is my birth date stored anywhere?
No - the calculation happens entirely in your browser and nothing is saved or sent anywhere.
