"biweekly-odd Occurs on odd weeks (ISOweek % 2 == 1)"
"Odd/Even and week numbers are based on the ISO week number. ISO weeks can be checked with %V in GNU date(1)"
I think some people have assumed it's even/odd week numbers in a month rather than even/odd week numbers counting from the epoch. Technically we have frequencies like "first-tuesday" and "third-tuesday" to address specific week numbers in a month rather than truly alternating weeks. Based on the existing description, that appears to be the intent. So it had been the first and third weeks of the month, so therefore the odd weeks. But then we at least have a mismatch between phrasing used and what yaml2ical generates, so the description does need to be updated.
