❓ Frequently Asked Questions
How accurate is this age calculator?
Our calculator is 100% accurate when given correct dates. It accounts for all calendar anomalies including leap seconds (when possible), daylight saving changes, and even the 10-day skip when the Gregorian calendar was adopted in 1582.
Can I calculate age for historical figures?
Yes! Our calculator works for any date from 1582 onward (when the Gregorian calendar started). For earlier dates, results are approximate due to calendar changes.
Why does the month count sometimes decrease?
This happens when the current date hasn’t reached your birth day yet. For example, if born on the 15th and today is the 10th, your “month age” decreases by 1 because a full month hasn’t passed.
How do you determine zodiac signs?
We use the tropical zodiac system (Western astrology) which divides the year into 12 equal signs based on the sun’s position at birth. This is the most commonly recognized system worldwide.
What’s the maximum date range supported?
Our calculator handles dates from October 15, 1582 (Gregorian calendar start) to December 31, 9999. For dates before 1582, results may not match historical records perfectly due to calendar reforms.
