Polygamy, as explained by dictionaries, means "married to more than one person at the same time".
In nations where polygamy is deemed illegal, laws often include terms preventing a person from running multiple marriages in parallel. However, there is a difference between parallelism and concurrency. And I'm wondering if people can legally run multiple marriages concurrently in these nations.
For example, can someone have 7 spouses named Sunday, Monday, ..., Saturday and rotate (divorce and remarry) at midnight each day? Is this violating any laws governing monogamous relationships?
(Clearly this once-per-day example is contrived and only meant to explore a technical possibility.)
