Frequently Asked Questions
How is my exact age calculated?
The calculator finds the difference between your date of birth and today (or your chosen date) in complete years, then remaining months, then remaining days. It's not just dividing total days by 365 — it accounts for varying month lengths and leap years.
Why is the seconds counter live?
The seconds counter updates every second to reflect the actual number of seconds you've been alive, counting from midnight on your birth date to the current moment.
How accurate is the zodiac sign?
The zodiac sign is based on your birth month and day using standard Western astrology dates. Note that the exact boundary date can shift by a day depending on the year — for borderline birthdays, both adjacent signs are possible.
How is the Chinese zodiac determined?
The Chinese zodiac cycles through 12 animals every 12 years. This calculator uses the calendar year (January 1 cutoff) rather than the Chinese New Year date for simplicity. For births in January or early February, your sign may differ.
