Why do you think healthcare workers use "military time" or the "24-hour time clock?"

There are 24 hours in a day...all you have to do is keep counting until 24!

• You will always have 4 numbers. Example: 0900 is 9am. 1600 is 4pm

• You do not use colons or am and pm.

• Some people think it is easier to add 12 to any time after 1 pm. Example: 5pm+12= 1700

Minutes...

• When minutes are added to the hours, they stay the same

• For instance, the time to the right is either 1010 or 2210 based on whether it is morning or evening.

• 
  

What about midnight?

• Again, there are only 24 hours in a day

• There is 2359 then 2400 OR you can use 0000

• There is no 2401. After midnight it is 0001, 0002, 0003, etc.
