Frequently Asked Questions
How is exact age calculated in years, months, and days?
Exact age is found by subtracting the birth date from today. Count full years first, then remaining full months, then remaining days, accounting for varying month lengths and leap years.
What is a zodiac sign and how is it determined?
Your Western zodiac sign is determined by your birth month and day. There are 12 signs, each covering roughly 30 days of the year, starting with Aries (Mar 21 – Apr 19).
How many days until my next birthday?
We calculate your next birthday date (this year or next year if it has already passed) and count the calendar days remaining from today.
