Student ProjectHi! I'm a student developer building Calculat in my spare time. I was tired of searching for basic math tools and having to click through 10 spammy popups, loan ads, and cookie trackers.

A military time converter translates standard 12-hour clock notation (with AM and PM) into 24-hour military notation (from 0000 to 2359 hours) and vice-versa. Used worldwide by armed forces, aviation, emergency services, hospitals, and transportation to eliminate ambiguity.
T_{24} = \begin{cases} H \pmod{12} & \text{if AM} \\ (H \pmod{12}) + 12 & \text{if PM} \end{cases}12:00 AM converts to 0000 hours, morning hours 1:00 AM–11:59 AM stay 0100–1159, 12:00 PM is 1200, and afternoon hours add 12 (1:00 PM becomes 1300).
Scenario: Convert 06:30 PM and 12:15 AM into military time.
06:30 PM: Add 12 to the hour: 6 + 12 = 18. Output: 1830 hours ("Eighteen Thirty Hours").
12:15 AM: Midnight hour resets to 00. Output: 0015 hours ("Zero Zero Fifteen Hours").
10:00 PM in military time is 2200 hours (pronounced "Twenty-Two Hundred Hours").
0800 is pronounced "Zero Eight Hundred Hours".
The 24-hour system eliminates any possible confusion between AM and PM, preventing potentially fatal medication dosage errors or tactical miscommunications.
0000 refers to midnight at the start of a day, while 2400 refers to midnight at the conclusion of a day.
