Using This Chart
How to Use the Military Time Reference Chart
This chart is designed for quick two-way lookup. If you know the military time and need the standard equivalent, scan the left column until you find it. If you know the standard time and need the military format, scan the second column.
Military → Standard
Find the four-digit time in the Military column. The Standard Time column shows the 12-hour equivalent. For times 1300–2359, you can also subtract 12 from the hour mentally.
Standard → Military
Find your standard time in the second column. AM hours: prefix with 0 for single-digit hours (9 AM = 0900). PM hours: add 12 to the hour (3 PM = 1500). Noon = 1200. Midnight = 0000.

Beyond the Chart
Memorization Tips — Ditch the Chart Faster
A printed chart is a useful crutch while you're learning, but the goal is to internalize military time so you don't need to look anything up. These strategies accelerate fluency.
The subtract-12 shortcut
For all PM hours (1300–2359), subtract 12 from the hour to get the standard time. This is the entire conversion rule for the afternoon and evening. 1600 − 12 = 4:00 PM. 1930 − 12 = 7:30 PM. Practice it 10 times with random times and it becomes automatic.
Anchor on the common times
Memorize: 0800 = 8 AM, 1200 = noon, 1500 = 3 PM, 1700 = 5 PM, 1800 = 6 PM, 2000 = 8 PM, 2100 = 9 PM. These seven anchors cover most common usage. Interpolate from there.
Phone trick
Go to Settings on your phone and switch the clock to 24-hour format. Keep it there for one week. You'll see military time every time you check the time — dozens of exposures per day. Most people report full fluency by day 5. After a week, switch back if you prefer — you'll be able to read military time on sight without thinking about it.
Midnight and noon: the two exceptions
Memorize these two as special cases: midnight is 0000 (not 2400), and noon is 1200. Everything else follows the arithmetic. These two are the only times that don't fit a simple pattern.
Note on Format
This chart shows military time in the no-colon format (1500), which is the correct written form for US military, aviation, and clinical documentation. Some international contexts use the ISO 8601 colon format (15:00) — the times are identical, but the written style differs. If your workplace uses colons, the same conversion logic applies.
