Making age calculations a little more fun
Fun Age Calculator starts with accurate date calculations, then lets Una the Unicorn take the numbers somewhere more playful.
What you can calculate here
The main tools answer everyday questions such as how old you are today, how many days you have been alive, when your next birthday falls and how old you were on another date.
The fun side of the site turns the same birthday into dog years, cat years and made-up fantasy ages. Real-world calculations are kept separate from entertainment so it is always clear which is which.
Privacy by design
The age calculators run in your browser. Your birthday does not need to be sent to a server or stored in a database for the calculations to work.
