Frequently asked questions
How is the exact age calculated?⌄
Subtracts birth date from target date, broken into years/months/days accounting for varying month lengths and leap years.
How accurate are the zodiac signs?⌄
Western zodiac uses birth month/day. Chinese zodiac uses 12-year animal cycle by birth year. Simplified solar method — lunar calendar births in Jan/Feb may differ.
What about leap years?⌄
Leap years are handled correctly. Feb 29 birthdays use Feb 28 in non-leap years. Total days count is always accurate.
Can I calculate age for past dates?⌄
Yes — enter any birth date and target date (past or present). Works for any date range, including historical dates.
