    0430 military time is 4:30 AM in regular 12-hour time — half past four in the morning, well before dawn for most of the year. Morning hours are the easy half of the system: from 0100 to 1159 the hour number stays the same, you simply drop the leading zero and add AM, so 0430 reads as 4:30 AM.

    Times like 0430 appear in early formations, deployment and flight departure schedules, fishing and hiking plans and hospital medication charts. Spoken military-style it is "zero four thirty"; 0430 and 04:30 are identical, and the leading zero is what marks it unmistakably as early morning rather than afternoon.

    This page opens with 0430 already converted to 4:30 AM. Keep using the form for any other value — it takes 0430, 04:30 or 4:30 AM, converts in either direction, and the 24-row chart below shows every hour from midnight (0000) to 2300. The tool runs entirely in your browser with nothing stored.

    Accepted Formats & Rules

    • Two-way conversion between 24-hour military and 12-hour AM/PM time.
    • Flexible parsing: 1730, 17:30, 930, 5:30 PM and bare hours all work.
    • Built-in 24-hour reference chart with midnight and noon notes.

    Key Benefits

    ✓ Converts both ways: military (24-hour) to regular 12-hour AM/PM time, and AM/PM time back to the four-digit military format.
    ✓ Forgiving input — type 1730, 17:30 or 5:30 PM and the parser understands it, flagging midnight (0000) and noon (1200) explicitly.
    ✓ Full 24-row reference chart from 0000 to 2300 rendered right on the page, so you can double-check any hour at a glance.

    Use Cases

    • • Instantly read a military time from a duty roster, flight plan or hospital chart as regular 12-hour AM/PM time.
    • • Write an appointment or shift given as 5:30 PM in the four-digit 24-hour format that schedules and logs expect.
    • • Settle the midnight and noon confusion for good: 0000 is 12:00 AM and 1200 is 12:00 PM, both flagged explicitly with a full 24-row chart to double-check.
