Cron explanation
Expression: */15 * * * * Runs at every 15 minutes; every hour; every day of month; every month; every day of week Next matching runs: 2026-04-28T00:15:00.000Z 2026-04-28T00:30:00.000Z 2026-04-28T00:45:00.000Z 2026-04-28T01:00:00.000Z 2026-04-28T01:15:00.000Z Warnings: - This tool explains common 5-field cron. Quartz seconds/year, time zones, and L/W/# modifiers may behave differently in your scheduler.
示例
工作原理
- Every 15 Minutes Cron Expression is a practical five-field cron schedule for quarter-hour batch work, cache refreshes, and periodic reports. The expression `*/15 * * * *` is designed for the common minute, hour, day-of-month, month, and day-of-week format used by many Linux crontab and scheduler interfaces.
- Use this preset when you want a known-good starting point that can be copied into a deployment script, CI scheduler, container task, or application job runner. The preview below explains the fields and shows the next matching run times using deterministic local logic.
- Quarter-hour schedules are widely supported and easy for humans to reason about. Cron dialects are not perfectly portable: Quartz, Kubernetes CronJob, GitHub Actions, systemd timers, and cloud schedulers may interpret seconds, time zones, or special modifiers differently. Always verify the expression in the scheduler that will execute it.
限制

- 生成结果是确定性的本地输出，但 scheduler、日志格式或基础设施 dialect 可能存在差异。

FAQ
Can I copy the Every 15 Minutes Cron Expression cron expression directly?
Yes, for common five-field cron schedulers. Review timezone and dialect behavior before using it in production.
Does this cron preset run on the server?
No. The explanation and next-run preview are generated locally in your browser or at static build time.
Why are Quartz seconds not included?
PureToolkit cron presets intentionally target the common five-field format to keep output predictable.
