Free Age & Calorie Calculators for US and Canada

Welcome to AgeAndCalorie.com — your trusted source for free, fast, and accurate online calculators. Whether you want to find your exact age down to the day, figure out how old your dog is in human years, or count every calorie in your Starbucks order, we have a dedicated tool built just for that. Our calculators are designed for everyday users across the United States and Canada who want quick, reliable answers without downloading an app or creating an account.

We built this platform around two core needs: understanding age and managing calories. These two topics affect millions of people every single day — from parents curious about their child’s development milestones, to fitness enthusiasts tracking their daily calorie burn, to pet owners wanting to better understand their furry family members. Every tool on this site is 100% free and works instantly on any device.

Age Calculators — Know Your Exact Age

Age isn’t just a number — it shows up in legal documents, health screenings, school enrollment, retirement planning, and so much more. Our chronological age calculator is one of the most searched tools in the US and Canada, and for good reason. People need to know their precise age in years, months, and days for medical forms, insurance applications, and milestone tracking. Instead of counting manually, you can get your exact age in seconds.

Chronological Age Calculator

The chronological age calculator lets you enter your date of birth and instantly see your age broken down into years, months, weeks, and days. It’s especially useful for healthcare providers, educators, parents tracking child development, and anyone filling out official paperwork that requires your precise age.

Dog Age Calculator

Did you know the old “1 dog year = 7 human years” rule is not scientifically accurate? Our dog age calculator uses updated research that factors in your dog’s breed size to give you a far more accurate conversion. Whether you have a small Chihuahua or a large German Shepherd, the results will differ — and our tool accounts for that.

Cat Age Calculator & Lunar Age Calculator

Cat owners across North America love our cat age calculator, which converts feline years into human equivalents using veterinarian-recommended formulas. And if you are curious about traditional age systems, our lunar age calculator tells you your age according to the Chinese and Korean lunar calendar — a system still widely used for cultural and astrological purposes.

Calorie Calculators — Eat Smart, Live Better

Calorie awareness is one of the most powerful tools for maintaining a healthy weight and lifestyle. But counting calories manually — especially at restaurants — is frustrating and time-consuming. That’s why we built dedicated calorie calculators for the most popular food chains and daily activities in the US and Canada.

Starbucks Calorie Calculator

Starbucks has hundreds of drink combinations, and the calorie difference between a grande oat milk latte and a venti caramel frappuccino with whip is enormous. Our Starbucks calorie calculator lets you pick your drink, size, milk type, and add-ons to get a precise calorie count. It’s perfect for health-conscious coffee drinkers who don’t want to give up their daily Starbucks run.

Subway Calorie Calculator

Subway is one of the most popular fast-food chains in North America, and it’s often chosen as a “healthier” option — but the calorie count can vary wildly depending on your choices. Our Subway calorie calculator walks you through bread, protein, cheese, toppings, and sauces to give you a complete picture of your meal’s nutritional impact.

Steps to Calories Calculator

Walking is one of the easiest ways to stay active, and the steps to calories calculator makes it easy to see the payoff. Enter your step count and body weight, and we’ll show you how many calories you burned. This tool is perfect for Fitbit and Apple Watch users who want to go beyond step counts and understand the real energy impact of their daily walks.

Cava & Treadmill Calorie Calculators

Cava is rapidly growing in popularity across the US, and our Cava calorie calculator helps you build your bowl and track every ingredient. For gym-goers, our treadmill calorie calculator factors in speed, incline, duration, and your weight to give you an accurate burn estimate — far more useful than the generic number on the treadmill screen.
