使用预设、通俗描述和接下来五次运行时间构建 Cron 调度。
使用方法
How to build a schedule
Choose a preset or type values into the minute, hour, day-of-month, month and day-of-week fields. The expression, description and upcoming runs update as you type.
- Pick a preset or enter your own five fields.
- Use * for every value and */n for intervals.
- Copy the finished expression with the copy button.
Field reference
Minutes and hours start at 0, days of month at 1, months at 1 (January) and days of week at 0 (Sunday). Ranges use a dash and lists use commas, for example 1-5 or 1,15,30.
常见问题
What does */5 mean?
It means every fifth value. In the minute field, */5 runs at minutes 0, 5, 10 and so on.
Does this support seconds?
The builder creates standard five-field cron expressions. Use the cron parser tool if you need to inspect six-field expressions with seconds.
