How to Use This Calculator
Pick a direction
Start with the format you have—military or standard time. Each converter works independently.

Use four digits for military time (HHMM) or h:mm with AM/PM for standard time. The calculator validates the entry instantly.
Copy the converted time
Use the result in shift schedules, flight plans, or communications that require a specific format.
Formula
24-hour ➝ 12-hour: Standard Hour = ((Hour + 11) mod 12) + 1, Period = Hour ≥ 12 ? PM : AM.
12-hour âžť 24-hour: Military Hour = (Hour mod 12) + (Period = PM ? 12 : 0). Midnight (12 AM) maps to 00 hours.
Minutes remain unchanged in both conversions; ensure the range is 00-59.
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Military time avoids ambiguity by using a 24-hour clock. Airlines, hospitals, emergency services, and global teams use it to prevent scheduling errors. Converting between the two formats helps you align with any audience.
The calculator validates both inputs and highlights edge cases like midnight (0000) and noon (1200). Negative or malformed inputs are flagged immediately so you can correct them before sharing the schedule.
You can copy either format directly for emails, dispatch logs, or calendar entries and trust that the conversion is accurate.
Frequently Asked Questions
Why does midnight convert to 0000 instead of 2400?
0000 is the official representation of midnight in military time. 2400 is rarely used and would indicate the end of a day, not the start.
How do I represent times before 10:00 AM?
Add a leading zero. For example, 7:05 AM becomes 0705, and 9:30 AM becomes 0930.
Can I enter seconds?
This tool focuses on hours and minutes. For hh:mm:ss conversions, convert the seconds separately or append them manually after conversion.
What about negative values?
Negative signs are allowed to help illustrate time zone offsets, but most scheduling scenarios use non-negative times.
