Age Calculator: Calculate Your Exact Age and Discover Your Zodiac Sign

Calculating age accurately is useful in many formal and practical situations, from government paperwork to insurance planning to simple curiosity. Our calculator computes your age in years, months, days, and hours.

Age Calculation Methods

Gregorian Method (Most Common) Age = today's date − birth date. But this requires precision in accounting for leap years and months with different day counts.

Hijri (Islamic) Method Many government bodies in Saudi Arabia and the Gulf calculate age using the Hijri calendar. The Hijri year is approximately 11 days shorter than the Gregorian year, meaning your Hijri age is slightly older than your Gregorian age.

A person aged 30 Gregorian years is approximately 30.9 Hijri years old.

Western Zodiac Signs

Your birth date determines your astrological sign under the Western calendar: - **Aries:** March 21 – April 19 - **Taurus:** April 20 – May 20 - **Gemini:** May 21 – June 20 - **Cancer:** June 21 – July 22 - **Leo:** July 23 – August 22 - **Virgo:** August 23 – September 22 - **Libra:** September 23 – October 22 - **Scorpio:** October 23 – November 21 - **Sagittarius:** November 22 – December 21 - **Capricorn:** December 22 – January 19 - **Aquarius:** January 20 – February 18 - **Pisces:** February 19 – March 20

FAQ

How does the age calculator account for leap years?
A leap year has 366 days instead of 365. The calculator automatically accounts for this when computing exact days between two dates, giving you the correct day count without rounding errors.
What is the difference between chronological and biological age?
Chronological age is the number of years since birth. Biological age reflects your body's actual condition and is influenced by your lifestyle and health. A 50-year-old can have a biological age of 40 or 60 depending on their health.
How do I convert my Gregorian age to Hijri?
Multiply your Gregorian age by 1.0307 for an approximate Hijri age. For example: 30 × 1.0307 = approximately 30.9 Hijri. Or use our calculator for precise conversion based on your birth date.
Is there legal significance to a birthday?
Yes. In Egypt, turning 18 activates full legal capacity. Age 21 applies to some contracts. Precise timing matters for army enrollment, elections, licensing, and more.
How do I calculate my age at a future date?
Enter your birth date and the target future date in our calculator, and it will compute your age on that day. Useful for planning: how old will you be at retirement, at your child's wedding, or other milestones.
