How It Works
The calculator handles leap years correctly using JavaScript's native Date arithmetic, so age in years/months/days is always accurate to the day.Frequently Asked Questions
Does it handle leap years correctly?
Yes. The calculator uses native date arithmetic that respects leap years, including the rare 100-year and 400-year exceptions. Someone born on Feb 29 will see their next birthday on the next leap year's Feb 29.
Why does my age in days not equal years × 365?
Because of leap years. A 30-year-old has lived through approximately 7 or 8 leap years, adding extra days. The 'days' field shows the exact count from your DOB.
Is the zodiac sign Western or Vedic?
It's the Western (tropical) zodiac, based on the date ranges most familiar in Western astrology. Vedic astrology uses different cusps.
