Question 2

What is 18:00 in 12-hour time?

Accepted Answer

18:00 in 12-hour time is 6:00 PM. To convert, subtract 12 from any 24-hour value above 12: 18 − 12 = 6, then add PM. Any hour from 13:00 to 23:59 is PM; hours from 01:00 to 11:59 are AM. Special cases: 00:00 is 12:00 AM (midnight) and 12:00 is 12:00 PM (noon).

Question 3

What is military time?

Accepted Answer

Military time is a 24-hour clock system that expresses time as a four-digit number from 0000 (midnight) to 2359 (11:59 PM), with no AM or PM. It is written without a colon — 1800 instead of 18:00 — and spoken with 'Hours' at the end (e.g., 'Eighteen Hundred Hours'). Military time is used by the US Armed Forces, NATO, hospitals, emergency services, and aviation to eliminate AM/PM confusion.

Question 4

What is 2026 in Roman numerals?
