- Find "ratio anniversaries" for two
birthdays. These are dates when the ratio of the two ages
(measured in days) are closest to some small integer fraction,
like 5/3 or 3/4. In detail, here is what this script does:
Given two birth dates, find all ratios

I wrote this page on impulse, finishing it on the last day of 2004. It occurred to me that Anna and Lizzie were turning 10 and 5 respectively in the summer of 2005, and that Anna would therefore be twice as old as Lizzie some time during the year. I used this page to find the exact date (the girls want to have a party), and then discovered that I would be ten times as old as Lizzie in March, and five times as old as Anna on 3-Jan-2005!*p/q*such that*age1/age2 = p/q*, where*p*and*q*are integers between 1 and 10 (with some extra whole-number multiples thrown in if the ages are very different).
