Need to automate this in spreadsheets? Here is the standard, optimized Excel formula to convert raw 4-digit military time (stored in cell A1) to a standard standard time format.
=TEXT(TIME(LEFT(A1,2),RIGHT(A1,2),0),"hh:mm AM/PM")
To convert standard AM/PM time to military time: For AM hours from 1:00 AM to 11:59 AM, keep the hours the same and pad with a leading zero if needed (e.g., 9:15 AM becomes 0915). For PM hours from 1:00 PM to 11:59 PM, add 12 to the hour value (e.g., 5:30 PM becomes 1730). For 12 AM (midnight), convert the hours to 00 (e.g., 12:45 AM becomes 0045).
To convert 24-hour military time back to standard regular time: If the military hour is 00, it represents 12:XX AM. If the military hour is between 01 and 11, it is AM and the hour remains identical. If the military hour is exactly 12, it represents 12:XX PM. If the military hour is between 13 and 23, subtract 12 from the hours to get the PM standard time (e.g., 1730 minus 12 hours is 5:30 PM).
The standard formula is: Standard PM Hour = Military Hour - 12 (for hours 13 through 23), and Military PM Hour = Standard Hour + 12 (for hours 1:00 PM through 11:59 PM).
In most military and aviation applications, midnight is represented as 0000 to denote the start of a new operational day. While 2400 is sometimes used to denote the exact end of a day, 0000 is the standard format used in digital systems.
