Frequently Asked Questions
How accurate is the age calculation?
The calculator is extremely accurate, accounting for leap years, varying month lengths, and exact date differences. It calculates down to the exact day, hour, minute, and second.
Why do the life statistics show such large numbers?
Life statistics are based on average daily rates: ~100,000 heartbeats, ~20,000 breaths, ~8 hours sleep, and ~3 meals per day. These add up quickly over years, demonstrating the amazing activity of human life.
Can I calculate age for historical dates?
Yes! You can calculate the age of historical figures or determine how old someone was at any point in history by using the "Age Between Two Dates" option.
What if someone was born on February 29th (leap day)?
The calculator properly handles leap year births. For non-leap years, we consider February 28th as the birthday date for age calculations and birthday countdowns.
How does the calculator handle different time zones?
The calculator uses your browser's local time zone for current date calculations. For historical comparisons, it uses the dates as entered without time zone adjustments.
Why might my age be different by a few hours on my birthday?
If you're checking your age on your birthday, the exact time of birth matters. The calculator shows your age change at midnight on your birthday date, not at your exact birth time.
