How to Convert Military Time to Standard Time
Military time uses a 24-hour clock that runs from 00:00 to 23:59. Unlike the 12-hour clock, it does not require AM or PM to identify the time of day.
For times from 01:00 through 11:59, the hour remains the same and AM is used. For times from 13:00 through 23:59, subtract 12 from the hour and use PM. Midnight (00:00) converts to 12:00 AM, while noon (12:00) remains 12:00 PM.
Military Clock Notation & Midnight Conventions
In military-style four-digit notation, colons are omitted (for example, 17:30 is written as 1730 hours, and 06:00 is written as 0600 hours). While some logistical and operational conventions use 2400 to indicate the exact end of a day, digital time inputs and standard conversion tools operate within the range of 00:00 through 23:59.
How Do Time Zone Conversions Work?
Time zones describe how local clock time relates to Coordinated Universal Time (UTC). To compare two locations, you need to know their UTC offsets and whether daylight saving time applies on the selected date.
For example, New York (America/New_York) and Los Angeles (America/Los_Angeles) generally maintain a three-hour time difference, even though their UTC offsets change during daylight saving time (from EST UTC−5 to EDT UTC−4, and PST UTC−8 to PDT UTC−7). In contrast, regions like India (Asia/Kolkata, UTC+5:30) do not observe daylight saving time, meaning the offset difference between India and US time zones shifts by one hour twice a year. Converters that use geographic time zones and an actual date account for these seasonal transitions.

Convert CalendarFrequently Asked Time Conversion Questions
Short explanations for common clock formats and time zone questions.
What is 1730 in military time?
1730 means 5:30 PM on a 12-hour clock. Subtract 12 from the hour (17 − 12 = 5) and keep the minutes unchanged.
What is 6 PM in military time?
6:00 PM is 1800 in military time, or 18:00 in standard 24-hour notation. For PM times from 1:00 through 11:59, add 12 to the hour while keeping minutes the same.
Is 12:00 AM midnight or noon?
12:00 AM is midnight (00:00 on a 24-hour clock), while 12:00 PM is noon (12:00 in 24-hour time). Remembering that AM stands for Ante Meridiem (before midday) and PM stands for Post Meridiem (after midday) clarifies this distinction.
Is 2400 the same as 0000?
Both refer to midnight, but in different date contexts. 0000 marks midnight at the start of a calendar day, while 2400 is sometimes used to denote midnight at the end of that day. Most digital clocks, scheduling systems, and conversion tools operate strictly within the 00:00 to 23:59 range.
How do I convert 24-hour time to 12-hour time?
For hours from 01:00 to 11:59, keep the hour and append AM. For 12:00, use 12:00 PM. For hours from 13:00 to 23:59, subtract 12 from the hour and append PM. For 00:00, use 12:00 AM.
Why do time zone differences change during daylight saving time?
Time differences change when one location switches between standard time and daylight saving time while another location does not, or when they change clocks on different calendar dates. For instance, India Standard Time (UTC+5:30) does not observe daylight saving, so its time gap with US Eastern Time (America/New_York) is 9.5 hours during Daylight Saving Time (EDT, UTC−4) and 10.5 hours during Standard Time (EST, UTC−5).
