Frequently Asked Questions (FAQ)
What is the difference between international chronological age and traditional lunar age?
Chronological age represents the standard global method where a person starts at age 0 at birth and increments by 1 on each Gregorian calendar birthday. Traditional lunar age (common in East Asia) counts a newborn as 1 year old at birth and increments the age by 1 on each subsequent Lunar New Year, representing cultural calendar concepts.
How does the date engine ensure mathematical accuracy with historical leap years?
Our engine strictly adheres to the ISO 8601 calendar standard. It tracks every Gregorian leap year (e.g., 2000, 2024, containing 366 days with February 29th) within your lifetime. It calculates absolute elapsed days, hours, and seconds with zero drift, adjusting for historic calendar variations.
