What Is 1500 Military Time? 3:00 PM Explained

1500 military time is 3:00 PM. The first two digits are the hour on a 24-hour clock, and the last two digits are the minutes. Because 15 is greater than 12, this is an afternoon or evening time.

Quick Conversion

Separate 1500 into 15 hours and 00 minutes. For a PM time after 1259, subtract 12 from the hour:

15 - 12 = 3

Keep the minutes unchanged. The result is 3:00 PM. The date and time zone do not change this hour conversion; they only determine where and on which date the time occurs.

How to Say 1500

In military-style speech, 1500 is commonly read as “fifteen hundred hours.” In ordinary 24-hour usage, people may simply say “15:00.” In 12-hour notation, say “3:00 PM.”

Do not insert PM after a four-digit military time. Writing 1500 PM mixes two clock systems. Use either 1500 or 3:00 PM.

Nearby Times

• 1430 = 2:30 PM
• 1500 = 3:00 PM
• 1530 = 3:30 PM
• 1600 = 4:00 PM

These examples show the rule: for hours 13 through 23, subtract 12 from the hour and preserve the minutes.

A Practical Example

A remote meeting scheduled for 1500 UTC begins at 3:00 PM in UTC. Participants must then convert that instant to their own time zones.

When a schedule crosses midnight, attach the date. A line that only says 1500 identifies a time of day, not which occurrence of that time is intended.

Common Mistakes

• Treating 1500 as a duration of 15 hours and 00 minutes
• Subtracting 12 from the minutes instead of the hour
• Dropping a zero from the minutes when the value is below 10
• Adding AM or PM to an already unambiguous 24-hour value
• Converting the clock but forgetting that two time zones may use different dates

The word “hours” is optional in ordinary writing. It can clarify military speech, but a timetable usually needs only the four digits.

The Answer

1500 military time converts to 3:00 PM. Subtract 12 from the 15-hour value, leave 00 minutes unchanged, and use PM.
