Age Calculator: Birthdays

Age Calculator shows how old the people in your life are, down to the day, and when each of them has their next birthday. Add someone once with their date of birth and the answer is always one glance away: no arithmetic, no account, no internet needed.

🎂 THE NEXT BIRTHDAY, FRONT AND CENTER
• Whoever has the next birthday sits at the top, with the age they are turning standing as number candles
• See the date, the weekday and how many days are left
• On the day itself the candles are lit, and a tap blows them out

📅 EXACT AGE IN YEARS, MONTHS AND DAYS
• Every person shows their exact age, for example 31 years, 11 months and 28 days
• The countdown to every next birthday, with its weekday
• Date of birth and star sign at a glance
• Birthdays on 29 February are celebrated on 28 February in common years

👥 YOUR PEOPLE, YOUR ORDER
• Sort the list by next birthday or by name
• Adding someone takes seconds, and the form shows their age and next birthday before you save
• Deleted someone by mistake? Undo brings them back
