Frequently Asked Questions
- How is exact age calculated?
- We count full years from your date of birth to the chosen date, then the remaining whole months and days. For example, someone born on January 15, 2000 is 26 years, 5 months and 13 days old on June 28, 2026.
- How many days until my next birthday?
- The calculator finds your next birthday after the chosen date and counts the days remaining. If today is your birthday, it shows that instead.
- What is a star sign and how is it determined?
- Your star sign (Western zodiac) is set by your birth month and day — for example, anyone born March 21 to April 19 is an Aries. The calculator detects it automatically.
- Can I calculate age as of a past or future date?
- Yes. Change the "Age at date" field to any date to find how old you were, or will be, on that day.
