Sıkça sorulan sorular
›What are the 5 cron fields?
minute (0-59), hour (0-23), day-of-month (1-31), month (1-12), day-of-week (0-7, both 0 and 7 mean Sunday).
›How do I run something every 15 minutes?
Use */15 * * * * — that's 'every 15 minutes, every hour, every day'.
›What does the '?' mean?
Quartz/Java cron uses '?' to mean 'no specific value' in either day-of-month or day-of-week. Standard Unix cron doesn't use it.
›Day of week — is Sunday 0 or 7?
Both, in standard Unix cron. Some systems (Quartz) use 1-7 with Sunday = 1. We follow Unix convention.
›Is the explainer free?
