The short answer: An army time chart shows every hour of the day in standard 12-hour time next to its military time, or 24-hour clock, equivalent, so you can convert a time at a glance. Our free printable army time chart lists all 24 hours and every half hour, shows how to say each one out loud, and adds a second page with a 24-hour log for medications, shifts or care notes.
It's made for recruits and military families, nurses and caregivers, shift workers, students, and anyone who has stared at "1745" and counted on their fingers.

How to use the army time chart
- Print both pages. Print the PDF on US Letter paper. Post page 1 where you need it, such as near a desk or on the fridge.
- Find the standard time. Find the time in the first column, such as 3:00 p.m.
- Read across to military time. Read the military time in the second column, 1500, and how to say it.
- Use the half-hour column. For times on the half hour, use the fourth and fifth columns, like 1530 for 3:30 p.m.
- Add the minutes. For any other minute, keep the hour from the chart and add the minutes, so 3:47 p.m. is 1547.
- Log your day in 24-hour time. Use page 2 to log medications, shifts or tasks by the hour so nothing gets mixed up.
How military time works
Military time counts the hours of the day from 00 to 23 instead of restarting at 12. It's written as four digits with no colon and no a.m. or p.m. The first two digits are the hour and the last two are the minutes.
- Morning (midnight to 11:59 a.m.): write the hour with a leading zero. 6:00 a.m. is 0600.
- Noon hour: 12:00 p.m. is 1200, and 12:45 p.m. is 1245.
- Afternoon and evening: add 12 to the hour. 3:00 p.m. is 1500 and 11:30 p.m. is 2330.
- Midnight: 0000, the start of a new day. 12:30 a.m. is 0030.
Minutes never change. Only the hour does.

How to convert any time, step by step
- Look at a.m. or p.m. If it's a.m., keep the hour. If it's p.m. and the hour is 1 to 11, add 12.
- Write the hour as two digits. 7 a.m. becomes 07 and 7 p.m. becomes 19.
- Add the minutes unchanged. 7:20 p.m. becomes 1920.
- Drop the colon and the a.m. or p.m. Military time doesn't need either.
- Going the other way? If the hour is 13 to 23, subtract 12 and add p.m. So 2215 is 10:15 p.m.
How to say military time
Say it as two pairs. 0900 is "zero nine hundred," 1300 is "thirteen hundred," and 1645 is "sixteen forty-five." When the minutes are 00, say "hundred." When the hour starts with 0, say "zero," which the military prefers over "oh." Adding "hours," as in "fourteen hundred hours," is common in speech but never written.
Military time and Zulu time
The armed forces, pilots and forecasters often add a letter for the time zone. Z, or Zulu, means Coordinated Universal Time (UTC), the world's time standard. The National Hurricane Center explains that its advisories use UTC so readers in every time zone work from the same clock, and NIST keeps the official U.S. version, UTC(NIST), in step with the international standard. In winter, Eastern Standard Time is 5 hours behind UTC, so 1700Z is noon in New York.
Use 24-hour time for care and medication logs
A.m. and p.m. mix-ups are an easy way to double a dose or miss one. That's why many hospitals use military time. If you're caring for a parent, a partner or a child with a medication schedule, page 2 of the free printable gives you a 24-hour log with a row for every hour.

Frequently asked questions
How does an army time chart work? An army time chart lists every hour of the day in standard 12-hour time next to its military, or 24-hour, equivalent. Morning hours keep the same numbers with a leading zero, so 7:00 a.m. is 0700. Afternoon and evening hours add 12, so 7:00 p.m. becomes 1900. Find the time in one column and read across.
How do you convert regular time to army time? To convert regular time to army time, drop the colon and the a.m. or p.m. For times from 1:00 a.m. to 12:59 p.m., write the hour as two digits, so 9:30 a.m. is 0930 and 12:15 p.m. is 1215. For 1:00 p.m. or later, add 12 to the hour, so 4:45 p.m. becomes 1645.
How do you convert army time back to standard time? To convert army time back to standard time, look at the first two digits. If they're 01 through 11, it's a.m., and you just drop the leading zero. If they're 12, it's the noon hour. If they're 13 through 23, subtract 12 and add p.m., so 2130 is 9:30 p.m. Hour 00 is the midnight hour.
What is midnight in army time? Midnight in army time is usually written as 0000, which marks the start of a new day, and 12:30 a.m. is 0030. Some organizations write 2400 to mean the end of a day, such as a shift that ends at midnight. Our army time chart uses 0000 so every hour from midnight to 11 p.m. appears exactly once.
How do you say military time out loud? Say military time as two pairs of digits. 1400 is fourteen hundred, 0800 is zero eight hundred or oh eight hundred, and 1730 is seventeen thirty. The military usually says zero rather than oh for a leading 0. Some people add hours at the end, like fourteen hundred hours, which is common but optional.
Is army time the same as military time and 24-hour time? Yes, army time, military time and the 24-hour clock all count the hours of the day from 00 to 23, so they show the same numbers. Military time is usually written without a colon, like 1500, while much of the world writes 24-hour time with one, like 15:00. Hospitals, airlines and emergency services use it too.
What is Zulu time in the military? Zulu time is the military name for Coordinated Universal Time, or UTC, which is the time standard used around the world. Military, aviation and weather forecasters use it so everyone works from the same clock regardless of time zone. For example, the National Hurricane Center lists advisories in UTC, and 1500Z is 10 a.m. Eastern Standard Time.
Why do hospitals and caregivers use military time? Hospitals, nurses and family caregivers often use military time because it removes any confusion between a.m. and p.m. A medication given at 0800 and one at 2000 can't be mixed up the way 8:00 could be. Page 2 of our free printable is a 24-hour log you can use for medications, feedings or care notes.
