Calculating…
Supports standard 5-field cron: minute, hour, day of month, month, day of week. Ranges (1-5), lists (1,15), steps (*/10), names (MON, JAN) and macros like @daily all work. Quartz-only features such as a seconds field, L, W and # are not part of standard cron. Cloud schedulers often run in UTC, so check which time zone yours uses.
