Age Calculator: Life & Days

About

Every day counts. Age Calculator is a quiet, private way to explore the days that make up a life. Choose a date of birth to see your age in years, months and days, your total days lived, and your next birthday countdown. LOOK AHEAD Calculate your age today or on another date. Find your next 1,000-day milestone and share your numbers using the iPhone share sheet. KEEP YOUR PEOPLE CLOSE Save names and birthdays on your device. Your list is sorted by upcoming birthdays. Tap a person to load their birthday in the calculator, or swipe to delete an entry. REMEMBER THEIR DAY Opt in to birthday notifications on your iPhone and choose the time. Reminders update when you save or delete a birthday. Delivery follows your notification and Focus settings. Open the app regularly to refresh reminders. CHOOSE YOUR LEAP-DAY PREFERENCE For February 29 birthdays, choose February 28 or March 1 for countdowns and reminders in non-leap years. PRIVATE BY DESIGN No account, ads, analytics SDKs or developer-operated backend. Calculations work offline, and saved birthdays stay in the app's local storage. Device backups may include app data. Sharing happens only when you choose it. Notification previews may show saved names on your Lock Screen. ONE PURCHASE A paid download with no subscription or in-app purchases. All included features are available immediately. Uses Gregorian calendar dates. It is not intended to determine legal age.
