We use weighted biological averages: approximately 16 breaths per minute and 10 blinks per minute over your total minutes lived since birth.

These peaks are based on human development studies. Physical peaks usually occur in the 20s, while cognitive focus and financial reasoning peak in the 40s and 50s.

Mars takes about 687 Earth days to orbit the Sun. Therefore, a "Martian Year" is nearly twice as long as an Earth year, making you appear younger there!

It is a mathematical visualization based on a standard global life expectancy of 80 years. It helps provide a perspective on your current life stage.

Absolutely. OTechy tools perform all calculations in your browser's local memory. No birth dates or personal data are ever sent to our servers.

Our algorithm precisely accounts for the extra day in February every four years (Leap Years), ensuring your total days lived and "Next Birthday" countdown are 100% accurate.

Chronological age is the time passed since birth (what this tool calculates). Biological age refers to how old your cells and tissues seem based on health and lifestyle factors.

For the most accurate result, the day and month are required. If you only know the year, most users default to January 1st of that year for an approximate calculation.

On average, a human heart beats about 80 times per minute. By the time you reach 30, your heart has likely beaten over 1.2 billion times!

We often think of age in years, but a year is 365 days. When you see the total cumulative days, it often highlights just how much time has truly passed!

Yes. If you provide your exact birth time, the tool can calculate your age down to the exact minute and second for a truly "instant" chronological snapshot.

A half-birthday occurs exactly six months after your actual birthday. Many people use this milestone to track mid-year goals or celebrate with small gatherings.

Our calculator automatically identifies the day of the week (e.g., Monday, Sunday) associated with your birth date using the Gregorian calendar algorithm.

Based on a standard average of 8 hours of sleep per night, you typically spend about one-third (33.3%) of your life asleep. Our tool helps visualize these biological milestones.

While our tool is mathematically precise for personal use, you should always rely on government-issued ID (like a Passport or Driver's License) for official legal age verification.
