You can get an extra birthday celebration every 1000 days! I discovered that I am 4012 days old . To find out how many days old you are, multiply 365 by your age, add one for each leap year since you were born, and add the number of days since your last birthday.
how many days old are you ?

ps: I can calculate it if you tell me how old you are and when your birthday is.
