Frequently Asked Questions
How is my exact age calculated? +
We calculate the difference between your date of birth and today's date (or your chosen date), counting full calendar years, months, and remaining days precisely — accounting for leap years and different month lengths.
Can I calculate someone else's age? +
Yes! Enter any birthdate and set the "As Of" date to any date you want. You can calculate historical ages or future projected ages too.
How are heartbeats calculated? +
We use an average resting heart rate of 70 beats per minute. This is an approximation — actual heartbeat count varies based on individual physiology and activity level.
