No you can't specify a date at the shutdown command but two alternatives exist:

1) The easiest is to use the at command. The following example will execute shutdown +5 at a specific time and day:

echo "shutdown +5" | at 10:05am 2019-01-19

2) if you do not mind using you calculator and want to shutdown in say 24hours (24*60=1440 minutes) and you are absolutely sure the system will not reboot in between:

shutdown +1440

2. If you do not mind using your calculator and want to shutdown in, say, 24 hours (24×60=1440 minutes) and you are absolutely sure the system will not reboot in between:

   shutdown +1440

The easiest is to use the at command. The following example will shutdown at 10:10am (10:10am + 5) and give a 5min warning (+5):

echo "shutdown +5" | at 10:05am 2019-01-19

but if you don't mind using you calculator and want to shutdown in say 24hours (24*60=1440 minutes):

shutdown -r +1440
