Cron 解析

將 Cron 表達式翻譯為自然語言與下次執行時間

cron 是在伺服器上按指定時間自動執行任務的標準排程表示法 (例如備份指令稿、報表發送、快取清理)。將 5 欄位 (分·時·日·月·星期) 表示式解析為自然語言和下次執行時間。

Cron Expression

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

排程

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.
