it s 4-8
its military time. 12 pm is 1200 hours... and so on 1 pm is 1300, 2pm is 1400 and so on. their are 24 hrs in a day so that is how military time goes by. your dad is right. its not complicated once you get used to using the military time standards...
Your dad is correct, and it is military time. You just subtract 4 from the number. Military time is 24 hours instead of house normal clocks/time is split into 2 twelve hour blocks of time am/pm.
your dad is right. in a 24h system 13:00 is 1pm 14:00 is 2pm and soand 24:00 is midnight
ok 20:00= 4 hours before midnight. figure it out
