ah well, two typos involved there.
The second one was mine - missed out the $.
The first was yours - you had xs: instead of xdt: for a
yearMonthDuration.

Having corrected that, I end up with first of June rather than 1st of
May, so I will go over the logic, but at least you've shown me how to
work with dates - thanks.
