Bi-weekly and bi-weekly the other week

Question:
Is there a way to run a job every second or third week on a specific day and time (week 1,3,5,7...) ? And similar, is there a way to slide it 1 week (week 2,4,6,8...) ? E.g. running jobA on Mondays in odd-numbered weeks, and jobB on even-numbered weeks.

I know it can be solved with modifying the job-function itself.

No file, test, or entry point is named. Review the repository's existing scheduling API and tests to determine how weekly intervals and specific weekdays are represented, then define how odd- and even-numbered weeks should be selected and how completion would be verified.
