Identify hours and minutes

The given military time is 2146.
The first two digits represent the hours: 21.
The last two digits represent the minutes: 46.

Convert hours to 12-hour format

Since the hours value 21 is greater than 12, subtract 12 to find the PM time:
\[
21 - 12 = 9
\]
This indicates the time is in the PM.

Combine hours, minutes, and period

The converted time is 9:46 PM.
