Please notice the input format should be “DD HH:MM”. DD means the day in the

month, HH is the hour, MM is the minute. All these should be 2 digits and 24-hour

system is used. Here you can not specify the second. This is a hardware limitation on

the RTC chip, and only day, hour and minute could be specified for scheduled

shutdown.

You can use “??” as wildcard, which gives you the possibility to make a repeatable

schedule. Please see the table below:

Please don’t use “?? ??:??” to schedule the next shutdown, or your Raspberry Pi will

keep being shutdown and you hardly have a chance to change this setting (unless

you remove the battery and force RTC to forget it).

According to the hardware limitation, not all patterns with wildcards are supported.

The rule is: wildcards have to show up from let to right, and there is no number

between two wildcards. So “?? ??:38” is OK, while “?? 16:??” is not supported.

Here are some examples of scheduling the shutdown:

 15 21:45 means 9:45 at night, on 15

in this month.

 ?? 23:30 means 23:30 at night everyday (daily schedule)

 ?? ??:15 means the 15th minute every hour (hourly schedule)

If you are running the GUI, you can specify the next shutdown time by clicking the

“Edit” button in the row:
