About this converter

Who runs this site

I'm Andrew Garcia, and I built and maintain militarytimeconvert.com on my own. It exists because every military time converter I could find was either buried under ads, made you press a button to get an answer, or gave you a PDF chart you had to pinch-zoom on a phone. This one converts as you type, works on a phone, has no ads and asks for nothing.

How the conversions are calculated

Every conversion on this site is arithmetic done in your browser — nothing is sent to a server, and there is no database of answers to fall out of date. The rules are the standard 24-hour clock conventions:

• Hours 0–11 keep their number and are padded to two digits, so 7:15 AM is 0715.
• Hours 13–23 are the PM hour plus twelve, so 6:30 PM is 1830.
• Midnight is 0000 at the start of a day and may be written 2400 when it closes one out.
• Noon is 1200 — it is neither 0000 nor 2400.
• Minutes never change between the two formats.

The decimal figures on the military minutes chart are minutes divided by sixty, rounded to two places, which is the convention payroll and nursing timekeeping systems use.

How it is checked

The conversion logic has an automated test suite that runs every hour of the day in both directions, plus the midnight and noon edge cases that most converters get wrong. The 24-hour chart and the minutes chart are generated from that same tested code rather than typed by hand, so the pages and the tool can never disagree with each other.

Corrections

If you spot something wrong — a conversion, a chart row, or a description of how a particular service writes its times — email hello@militarytimeconvert.com and I will fix it. Corrections are the fastest way to make this more useful to the next person.
