How old am I if I was born in 1990?

If born in 1990, you are 36 years old in 2026 (or 35 if your birthday hasn't occurred yet this year). Use this calculator for your exact age with months and days, accounting for leap years.

How do I calculate age from date of birth manually?

Subtract your birth year from the current year, then adjust by -1 if your birthday hasn't passed yet this year. For exact months and days, manual calculation is prone to errors due to varying month lengths. It's safer to use this tool, which computes it instantly in your browser.

Can I calculate age between two specific dates?

Yes. Use the "Specific Date" tab — enter any start date (as DOB) and any end date to find the exact duration between two dates. This is perfect for calculating contract durations, visa validity periods, and exam eligibility.

Does the calculator handle leap year birthdays (Feb 29)?

Yes, absolutely. If you were born on February 29th, the calculator accurately handles your birthday in non-leap years, using the closest valid date according to standard Gregorian calendar conventions.

Is my date of birth stored or shared with anyone?

No. Privacy is our top priority. All calculations run entirely locally in your web browser using JavaScript. Your date of birth is never uploaded to any server, never stored in any database, and never shared with anyone.

Can I use this for age verification and legal purposes?

Yes. This tool gives a precise mathematical age suitable for filling out forms, age verification, legal documents, Aadhar registration, school admissions, and checking competitive exam eligibility.

⚡ Major Life Milestones & Eligibility

Age is more than just a number; it's a metric for legal eligibility, health assessments, and personal milestones.

The Math: Why Manual Calculation Fails

Subtracting your birth year from the current year is often inaccurate because it ignores the months and days elapsed. For exact forms, you need the "Borrowing" method.

💡 The Leap Year Factor

Our algorithm handles the "February 29th" edge case perfectly. If you were born on a leap day, the calculator accurately determines your age during non-leap years, ensuring you never miss a day of your life's tally.

💡 Form Filling Guide

Many official applications (Aadhar, PAN, UPSC) require your age as of a specific date. Use our "Specific Date" tab to find your exact age for any deadline without manual errors.
