Cron 解析

将 Cron 表达式翻译为自然语言和下次执行时间

cron 是在服务器上按指定时间自动执行任务的标准调度表示法 (例如备份脚本、报表发送、缓存清理)。将 5 字段 (分·时·日·月·星期) 表达式解析为自然语言和下次运行时间。

Cron Expression

min (0-59) · hour (0-23) · dom (1-31) · month (1-12) · dow (0-7)

调度

09:xx, minute 0, weekday 1-5

使用方法

Type a five-field cron expression (minute, hour, day-of-month, month, day-of-week).
The tool translates each field into a plain-English description of the schedule.
A preview lists the next N run times so you can confirm the timing is what you expect.
Adjust the fields and the explanation and run times update immediately.

The expression 0 9 * * 1-5 is explained as "At 09:00, Monday through Friday" and the next runs list weekday mornings only.
The expression */15 * * * * is read as "Every 15 minutes" and shows the next fire times 15 minutes apart.
