How this works

Fields mode is for building a schedule from fixed parts like minute, hour, day, and weekday. Paste mode is there when you already have a cron string and just want to inspect it.

The expression and the human-readable description stay in sync, so you can confirm what the schedule actually means before it reaches production.

The next firing list uses your current timezone, which makes it easier to catch the wrong weekday or hour before you ship a bad schedule.
