Mathematical Explanation

Age calculation involves precise date arithmetic that accounts for leap years, varying month lengths, and time zones. The calculator uses sophisticated algorithms to determine exact age by comparing birth date to current date, handling edge cases like February 29th births and month-end dates. Life statistics are computed using established averages: 75 beats per minute for heartbeats, 16 breaths per minute, 8 hours of sleep per day, and planetary age calculations based on orbital periods. Milestone calculations use specific formulas, such as 1 billion seconds (approximately 31.7 years) and 10,000 days (approximately 27.4 years), providing meaningful benchmarks for life measurement.
