Establishment of a series chronology

. Since the picture was two years old at the time, this corresponds to a then-current year of 2005, a figure which reflects the original publication date of the story in question. A variant of that same photograph is briefly glimpsed in one of Rin's flashbacks in chapter thirty-one, with the aforementioned date intact. However, while the events in the story take place some sixteen months after chapter six in official continuity, the story itself only published nearly two years later in late 2007, leaving an eight month delay between the passage of time in the series' fictional universe

Japanese elementary school year structure

The Japanese elementary school year, which begins in April and ends in March, can be divided into discrete time periods of two types: trimesters and vacations.

• The first trimester begins in early April, ends in late July, and is followed by six weeks of summer vacation.
• The second trimester begins in early September, ends in late December, and is followed by two weeks of winter vacation.
• The third trimester begins in early January, ends in late March, and is followed by two weeks of spring break.

As of April 1, 2002, a five-day-long school week has become the norm in all public elementary schools. Given that Kodomo no Jikan's fictional Futatsubashi Elementary is such a school, the first chapter takes place well after this aforementioned date, and the structure of the Japanese school year is well-defined and consistent between academic institutions of the same type, events in the series can be assigned to a specific trimester, vacation period, or even day if sufficient information is provided.
