The term 'DAY DIVISION' can be broken down into two parts: 'DAY' and 'DIVISION'. The word 'DAY' is a four-letter word, which can be solved as 'HOUR'. An HOUR is a unit of time that is equal to sixty minutes. A DAY is a period of twenty-four hours, or one full rotation of the Earth on its axis. A DIVISION is a part or portion of something, such as a company, organization, or government. Therefore, the term 'DAY DIVISION' can be interpreted as a part or portion of a DAY, such as a specific time frame or period of time.
