Military Time PM Hours Explained: 1300 to 2400 Conversion Cheat Sheet

Whenever you see a military time greater than 1200, simply subtract 2 from the second digit:

• See 1700? 7 - 2 = 5 PM.
• See 1900? 9 - 2 = 7 PM.
• See 1500? 5 - 2 = 3 PM.

This simple cognitive shortcut lets you read 24-hour clocks effortlessly without calculating two-digit arithmetic.
