How to Use the Age Calculator
1. Enter Your Birth Year
Find the input field labeled "If you were born in..." and type your birth year (between 1900 and current year). Make sure to enter a 4-digit year.
2. Click Calculate
Press the blue "Get My Age" button. The calculator will instantly process your birth year.

Your current age will appear in large numbers. You'll see either your age if your birthday has passed this year, or both ages (current and upcoming) if your birthday hasn't occurred yet.
Frequently Asked Questions
How does the age calculator determine my exact age? ▼
The calculator subtracts your birth year from the current year (2025). It shows you're either 25 or 26 years old if born in 1999, depending on whether your birthday has passed this year.
Why does it show two possible ages? ▼
Since we don't ask for your exact birth date, we show both possibilities. If your birthday has already occurred in 2025, you're the older age. If not, you're still the younger age.
What historical events can I discover from my birth year? ▼
Each year page (1930-2005) includes 5 major historical events from that year, covering technology, entertainment, politics, sports, and cultural milestones that shaped the world when you were born.
Can I calculate ages for years before 1930 or after 2005? ▼
Yes! While we have detailed event pages for 1930-2005, you can calculate any age by entering any year from 1900 to the current year in the calculator.
Is this calculator accurate for leap years? ▼
Yes, the basic age calculation works correctly for all years including leap years. The age difference is always based on full years passed since birth.
