Tools to help you monitor your health, fitness, and nutritional intake.
Check your Body Mass Index (BMI), calculate your Basal Metabolic Rate (BMR), estimate calorie needs, determine your age, or find your estimated due date. Use these tools as guides for a healthier lifestyle.
Ever wondered "how old am I exactly?" or need to know your precise age for an application? Our Age Calculator accurately determines your age in years, months, and days from your birth date. It also conveniently shows you how many days are left until your next birthday. Perfect for milestone tracking, official forms, or just for fun to see your age down to the day.
Assess your weight status with our Body Mass Index (BMI) Calculator. Input your height and weight (using metric or imperial units) to get your BMI score. This tool helps you understand where you fall within standard WHO categories (underweight, normal, overweight, obese) and includes a visual BMI chart. While BMI is a useful screening tool for potential weight-related health risks, remember it doesn't directly measure body fat or account for muscle mass.
Discover your Basal Metabolic Rate (BMR) – the calories your body burns at complete rest to maintain vital functions. Our BMR calculator uses the accurate Mifflin-St Jeor equation, considering your age, gender, height, and weight. Knowing your BMR is fundamental for understanding your body's baseline energy needs and is a key component in calculating your Total Daily Energy Expenditure (TDEE) for effective diet and fitness planning.
Estimate your Total Daily Energy Expenditure (TDEE) to understand your daily calorie needs for weight maintenance, loss, or gain. This calculator factors in your Basal Metabolic Rate (BMR) and your chosen physical activity level (from sedentary to extra active). Get personalized calorie targets to help you achieve your health and fitness goals, whether you're aiming for "calorie deficit for fat loss" or "calorie surplus for muscle gain."
Expecting a baby? Our Due Date Calculator provides an estimated delivery date (EDD) based on the first day of your last menstrual period (LMP), typically using Naegele's rule for a 40-week pregnancy. It also calculates your current gestational age. This tool offers a helpful preliminary estimate for planning, but remember that an early ultrasound and consultation with your healthcare provider are best for accurate pregnancy dating.
