Age Calculator

Free Online Age Calculator

The Tooloogle Age Calculator gives you the exact age between any two dates — your birthday and today, or any custom range — broken down into years, months, weeks, days, hours, minutes, and seconds. Calendar-aware logic correctly handles leap years, varying month lengths, and birthday boundaries so the result is always accurate.

How to Use the Age Calculator

1. Enter your date of birth (or any start date).

2. The current date is filled in automatically; change it if you need to calculate age at a future or past date.

3. Click Calculate — your full age breakdown appears instantly.

Common Use Cases

• Filling in age fields for job, visa, or government applications

• Verifying eligibility for age-restricted services or schemes

• Planning milestone birthdays, anniversaries, or retirement dates

• Calculating tenure, contract duration, or service length for HR

• Trivia and personal milestones (how many days you've been alive!)

Why Use Tooloogle's Age Calculator?

Everything runs in your browser — your date of birth never leaves your device. There's no signup, no ads in your data, no tracking. Works on phones, tablets, and desktops.

Tips for Accurate Results

• Double-check the date format — switch between DD/MM/YYYY and MM/DD/YYYY if your locale differs.

• For legal or official purposes, always confirm against the date on your birth certificate.

• Use the date-difference mode if you need the gap between two arbitrary dates rather than "age today".
