0300 Military Time Is 3:00 AM

By Sohail Manzoor · Updated

0300 = 3:00 AM

Zero three hundred

0300 in military time is 3:00 AM in standard time. Going the other way, 3 AM is written 0300. You say it “zero three hundred” or “zero three hundred hours”.

How to convert 0300 to standard time

The hour 03 is under 12, so it stays the same. Drop the leading zero, keep the minutes and add AM: 3:00 AM. To go back from 3 AM, write the hour with two digits, adding a zero in front, then the minutes, with no colon.

The last two digits are minutes, and they never change when you convert. Only the hour does, so every time from 0300 to 0359 sits in the 3 AM hour.
