Understanding Age Calculation

Leap Years: Our calculator accurately accounts for leap years (years divisible by 4, except century years not divisible by 400). This ensures your age in days is calculated correctly, even if you were born on or around February 29th.

Month Lengths: Different months have different numbers of days (28-31 days). Our calculator properly handles these variations when calculating age in months and days, ensuring accurate results regardless of birth date.

Time Zones: The calculator uses your local time zone for all date calculations. This means your age changes at midnight in your local time zone, just like in real life.

Zodiac Signs: Zodiac signs are determined by the sun's position relative to the constellations at your birth. The dates vary slightly year to year, but we use the standard Western astrology date ranges.

Days Until Birthday: The countdown to your next birthday is calculated from today (or your chosen comparison date) to your next birthday date, including both the start and end dates for accuracy.
