Frequently Asked Questions
How is my exact age calculated?
We calculate the precise difference between your date of birth and the target date, accounting for leap years and varying month lengths. The result is broken down into years, months, and days.
Can I calculate my age at a past or future date?
Yes. The Age At Date field accepts any date — past or future. This is useful for checking your age at a specific event or milestone.
Why do the total hours not account for daylight saving?
Total hours are calculated as total days multiplied by 24 for simplicity and consistency. Daylight saving adjustments would add complexity without meaningful value for most use cases.
Is my data stored anywhere?
No. All calculations happen entirely in your browser. Nothing is sent to our servers and nothing is stored.
