Isn't converting years+months+days into a number exactly what (localtime)[7] does?

No, it only combines month and day, not year, month and day. Without taking the year into account, you need to work around leap years. I didn't have to. You have to, and you did, but incorrectly. (Years divisible by 4 are leap years, except those divisible by 100, except those divisible by 400.)

Actually, it just occured to me that both of our solutions have the following problems: They can't handle dates < Jan 1st 1970 or >= (some point in) 2038. Not very useful.
