So, if we do twice a year, that would be be a Nov 1st recommended release and then a May 1st recommended release. That is probably a good place as any to start.
As a non-developer, I would go with whenever tends to be the period when developers have more free time (asking the other main developers).
(I think more people being online during releases can be argued either way about being a good or bad thing.)
I would actually go with quarterly "releases", so, when one gets skipped, it becomes a 6 months wait rather than an 1 year wait (and 9 months instead of 1.5 years if two get skipped).
