How it works
- Enter a 12-hour time (hour, minute, AM/PM) to see its 24-hour equivalent instantly.
- Or type a 24-hour time (like 0900 or 1430) to see it converted back to 12-hour format.
- Use the quick reference chart below for every hour of the day at a glance.
The formula
Converting 12-hour to 24-hour: for AM, midnight (12 AM) becomes 00 and other hours stay the same. For PM, add 12 to any hour except 12 PM itself (which is already 12):
24-hour = (12-hour mod 12) + (12 if PM else 0)
Example: 2:30 PM → (2 mod 12) + 12 = 14, so 2:30 PM = 1430.
FAQ
What is 1300 in regular time?
1300 military time is 1:00 PM. Subtract 12 from any military hour above 1200 to get the 12-hour PM hour.
