0 和 7 都代表星期天，你可以用你想要的，所以写0-6 或 1-7 具有相同的结果.

0 and 7 both stand for Sunday, you can use the one you want, so writing 0-6 or 1-7 has the same result.

此外，正如@Henrik 所建议的，可以通过缩短的日期名称来替换数字，例如 MON、THU 等:

Also, as suggested by @Henrik, it is possible to replace numbers by shortened name of days, such as MON, THU, etc:

0 - Sun      Sunday
1 - Mon      Monday
2 - Tue      Tuesday
3 - Wed      Wednesday
4 - Thu      Thursday
5 - Fri      Friday
6 - Sat      Saturday
7 - Sun      Sunday

图形上，* * * * * 要执行的命令代表:

或者使用旧样式:

 ┌────────── minute (0 - 59)
 │ ┌──────── hour (0 - 23)
 │ │ ┌────── day of month (1 - 31)
 │ │ │ ┌──── month (1 - 12)
 │ │ │ │ ┌── day of week (0 - 6 => Sunday - Saturday, or
 │ │ │ │ │                1 - 7 => Monday - Sunday)

 * * * * * command to be executed

最后，如果要逐日指定，可以用逗号分隔几天，例如SUN,MON,THU只会在星期日执行命令，星期一在星期四执行.

Finally, if you want to specify day by day, you can separate days with commas, for example SUN,MON,THU will exectute the command only on sundays, mondays on thursdays.
