I have * Example SCHEDULED: <%%(diary-float t 0 2)>
Which used to schedule an event on the 2nd sunday of every month. This has stopped working a month or two ago. I'm not sure if it is related to recent upgrades to Org 9 a few months ago. I'm now using 9.0.4. It works with the emacs default 8.2.10. Before I start bisecting a massive init.org file to try to find what might have broken this, I wanted to check if "diary-float" is working for others. Thanks, -k.
