Which tool do I need?

The BMI Calculator estimates body mass index from height and weight in metric or imperial units. BMI is a screening measure, not a diagnosis, so speak to a doctor for health advice.

The Age Calculator gives your exact age in years, months and days from a date of birth, plus a birthday countdown. The Age Difference Calculator finds the gap between two dates of birth, which is useful for couples, siblings and classmates.

The Password Generator creates random passwords with the length and character types you choose, directly in your browser.

Frequently Asked Questions

Is BMI accurate for everyone?
No. BMI does not measure body fat directly and can be misleading for athletes, older adults and pregnant women. Some health bodies suggest lower cut-offs for South Asian populations.
How is age calculated in years, months and days?
The calculator subtracts the date of birth from the chosen date, borrowing months and days where needed. For example, 15 August 2000 to 8 October 2026 is 26 years, 1 month and 23 days.
Are generated passwords stored anywhere?
No. The Password Generator creates passwords in your browser and does not send them to a server.
