Meet Age Calculator—the playful, precise way to explore time. Type in any date of birth and instantly see age broken down to years, months, days, hours, minutes, and even seconds. It’s wildly satisfying to watch your “seconds alive” tick upward in real time, and it’s genuinely useful when you need exact numbers for forms, milestones, or just plain curiosity.

Beyond the basics, the app adds delight with interesting facts around your age. Discover your 10,000th day alive and the exact date it lands on, find out which weekday you were born, see how many leap days you’ve lived through, and spot fun milestones like golden birthdays and 100th months. You’ll even uncover quirky date trivia—think palindrome dates or notable round-number counts—so every visit teaches you something new about your timeline.

Keeping track of loved ones is effortless with Family Profiles. Save birthdays for parents, grandparents, kids, and friends in one tidy place, and jump into any profile to view an instant age breakdown—again, right down to the second. No more digging through notes or messages to find dates; they’re organized, searchable, and ready whenever you are.

Birthdays become events you can actually plan for with a live countdown. See how long until the next celebration in months, days, hours, and minutes, plus the weekday it falls on. Planning a party or a surprise? Open a profile and get the answer in a heartbeat—then share the countdown so everyone’s in on the excitement.

Whether you’re tracking a newborn’s milestones by the week, prepping birthday surprises for the whole family, verifying age for applications, or simply geeking out over big round-number days, Age Calculator turns time into something you can explore, learn from, and enjoy. Save the important dates, watch the countdowns roll, and celebrate every moment—from the first second to the next big milestone.
