minute

0–59 · which minute of the hour fires.

hour

0–23 · hour of day (local timezone of the scheduler).

day of month

1–31 · calendar day.

month

1–12 · month of year.

day of week

0–6 · Sunday = 0 (7 treated as Sunday when pasted).

Scheduling semantics match lib/dev/cron: when both day-of-month and day-of-week are constrained (not *), either may match (OR). Seconds are not used here — five-field cron only.
