I see that `midnight-next' function does a similar calculation to the one my function does, though simpler because it only has to calculate seconds to the next midnight. I could see how midnight mode could be used to drive weekly events. The main downsides to this approach I'm seeing are (1) if you want events to occur at various times of day, the functions you pass in must launch their own timers with the offset time amount; (2) your timers wouldn't launch until at least midnight, if you had just (re)started Emacs; (3) `list-timers' wouldn't necessarily show all forth-coming timer events, only those timers that had already been launched in the midnight hook; (4) Your functions would still need to check what day it is. So, I'll keep using my function for now, though maybe rename it to `wee
 kly-next'. I'm still not sure where weekly-next would fit amongst the Emacs libraries, though timer.el still seems the most likely candidate.
