@Marvin how does Prefect parse cron and give a plain-text description of the cron expression?

Prefect uses the

croniter

library to parse cron expressions and create schedules that mimic traditional cron behaviors. Prefect's handling of cron schedules features options to toggle between treating certain elements with an "OR" logic, which can be more permissive, or an "AND" logic, which is more restrictive, akin to

fcron

rather than standard cron. However, it's important to note that features such as "R" for random and "H" for hashed expressions are not supported, which means if you were hoping for a little surprise in your cron scheduling, you'll have to look elsewhere—no randomness here! For a plain-text description, Prefect itself does not inherently provide a description of cron expressions. However, third-party libraries or custom scripts can be used to convert cron expressions into human-readable descriptions.
