Age Calculator: Exact Age, Birthday Countdown & Zodiac
What Is an Age Calculator?
An age calculator finds how old you are between two dates—usually from your date of birth to today. It can show exact years, months, and days, plus totals in weeks, hours, and more.
The XSular Age Calculator runs entirely in your browser. Your birth date never leaves your device.
How to Use the Age Calculator
Pick a calendar (Gregorian, Julian, Islamic Hijri, Persian, Hebrew, or Buddhist Era), enter your birth date, and choose today or a custom end date. Results update instantly with exact years, months, and days.
Each section is separate: calendar equivalents, exact age, next birthday, weekday born, total time lived, zodiac signs, and fun facts like leap years lived.
