Five fields: minute hour day-of-month month day-of-week. Six fields add second in front (as in Quartz, Spring and node-cron).
* any · 5 one value · 1,15 list · 1-5 range · */15 every 15th · 8-18/2 stepped range. Months JAN–DEC and days SUN–SAT work in any case; day-of-week 0 and 7 are both Sunday. ? means the same as *. Macros: @yearly @monthly @weekly @daily @hourly.
When both day-of-month and day-of-week are restricted, a day runs if either matches (standard cron). 0 0 13 * 5 runs on every 13th and every Friday.
Quartz L, W and # are not supported. Run times are computed in your browser's time zone or UTC; on a daylight-saving change a local time that is skipped does not run, and one that repeats can run twice.
Shortcut: Ctrl/⌘+Enter copies the description.
