How do you handle leap years and February 29th birthdays?

For people born on February 29th, we calculate their birthday as March 1st in non-leap years for age calculation purposes. All leap years between the birth date and current date are properly accounted for in the total day count.

Can I calculate my age on a specific future date?

Yes! Use the Future Age tab to enter any future date and see exactly how old you'll be on that day. This is perfect for retirement planning, milestone celebrations, or any future event planning.

How is the age difference between two people calculated?

The age difference is calculated by finding the exact time difference between two birth dates. We show the difference in years, months, days, and total days to give you a complete understanding of the age gap.

What life events are included in the life events timeline?

We include common milestones like birth, starting school, becoming a teenager, legal adulthood, retirement age, and more. These events help you visualize your life journey and plan for future milestones.

How are zodiac signs and generations determined?

Zodiac signs are calculated based on traditional Western astrology dates. Generations are determined using commonly accepted birth year ranges (Baby Boomers: 1946-1964, Gen X: 1965-1980, Millennials: 1981-1996, Gen Z: 1997-2012, etc.).
