Ask HN: How to document scheduled jobs for non-technical users

I work as an analyst on a business application that has around 100 scheduled jobs. 75% of these are launched by cron, the rest by a user-managed scheduling subsystem. Most jobs run every day (some more than once a day) and a minority run only on specific days (first of month, end of year, only on sundays etc.). I would like to be able to provide some visual map allowing users to better understand what happens when, and how to deal with ad-hoc processes (crisis management). Ideally I would prefer to avoid dedicated tools - I am looking mostly for example of a way to proceed. (but if you happen to know of a specific domain language that automagically produces schedule "infographics" from text data I will gladly have a look)
