Frequently asked questions
How accurate is the calculation?
It accounts for varying month lengths and leap years, so the result is calendar-accurate down to the day.
What if my "as of" date is before my birth date?
The tool will still calculate, but the values will be negative so you can verify the input.
Is my date of birth stored anywhere?
No. The math runs entirely in your browser. Nothing is uploaded.
