Frequently asked questions

How do you read military time?

Military time uses a 24-hour clock with no colon — 0000 is midnight, 1200 is noon, and 1300 is 1 p.m. After noon, add 12 to the standard hour (3 p.m. = 1500).

What is a Julian date?

The military Julian date is the day of the year numbered 001–365 (or 366 in a leap year), often prefixed with the year — used to date-stamp documents and supplies.
