If no one else has done it then I guess I'll bite the bullet and figure it out. I'll post my code here in a couple of days if I get it sorted. I imagine the only tricky bit will be allowing for leap years.

P.S. Chris, this might be a good built-in function for the AHK 'Transform' command in the future.

Cheers guys,

C.

**Update:**Ok, here's what I got. And it didn't take too long at all. Seems to work so far. If anyone can see any mistakes or ways to improve its efficiency, please point them out.

It only goes one way (AHK to Unix - maybe someone else can do the reverse some time?), and will work for dates between 1970 and 2400.
