Frequently Asked Questions
Does this calculator account for Leap Years?
Yes! The JavaScript Date engine perfectly accounts for leap years, meaning every February 29th is factored into your exact total day count.
What timezone does it use?
The calculator uses the local timezone set on your computer or mobile phone. This ensures the "Today" calculation perfectly matches your current reality.
Can I calculate age between two past dates?
Yes. Change the "Calculate Age At" field from today to any date in the past (or future). The live ticker will pause and show you the exact static age between those two specific dates.
Is my date of birth saved online?
Absolutely not. We have no databases connected to this tool. If you use the "Save to History" feature, it saves the date to your browser's local cache (localStorage) which only you can access.
