~HESI HINT~ To convert to military time before noon, simply include a zero before the numbers 1 through 9 for am. For example, 9:35 am regular time coverts to 0935 military time. The zero is not needed when converting 10 am or 11 am. If the time if after noon, simply add 12 to the hour number. For example, 1:30 pm regular time converts to 1330 military time (1+12=13). Midnight, or 12 am, is converted to 0000. Noon, or 12 pm, is converted to 1200.
