How do you express 8:30 PM in military time?

To express 8:30 PM in military time, you convert the standard 12-hour clock format to the 24-hour format used in military time. In military time, the hours after noon are expressed by adding 12 to the standard hour. Since 8 PM is in the evening, you take 8 and add 12, which gives you 20.

Then, you simply add the minutes. Therefore, 30 minutes past 8 PM is written as 2030 in military time. This is why the correct expression of 8:30 PM is 2030.

The other options do not correspond to the correct conversion for that specific time.
