🔍 Key Concepts

• International/maritime date formats (how day, month, and year are ordered) • How months are written numerically (March = 03) • What the leading letter "D" usually stands for in message/date groups

💭 Think About

• First decide which two digits in each option most likely represent the year 1980. • Then decide which two digits would represent March, and which two would represent the 12th day. • Check each choice and ask: if I read these six digits as day–month–year or year–month–day, which one correctly matches 12 March 1980?

✅ Before You Answer

• Verify which part of the date should come first in standard maritime/International date formats for messages (day, month, or year). • Confirm that March is correctly shown as 03, not 12 or 80. • Ensure that the remaining two digits correctly represent the 12th day and the year 1980 in the chosen format.
