Being "operational" means having completed shakedown trials, embarked aircraft, and not being repaired for combat damage or being overhauled or refitted.

Operational times begin at 7 December 1941 for carriers commissioned before then.

Operational times end at 2 September 1945 for carriers still in service at that time.

"Total Mo. Since 1st Operational" is the number of months that elapsed between being commissioned as an aircraft carrier and becoming operational for the first time.

The total number of months between first becoming operational and the end of service is divided into months "operational", under repair, or being refitted, etc. ww2dbase
