The calendar is a chart displaying the number of days, weeks, and months of a year, showcasing any event that may occur during a particular day. There are four months of each year; each month corresponds to a season - spring, summer, autumn, and winter - and contains 28 days each. There are four weeks and seven days to make up a week; the seven days are as follows: Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday. After four months, the calendar cycles to the next year, starting back to the first month of the year.
The format for labeling the game time can be written in two different ways: a simplistic version and a formal version. The simplistic version is written as month.day (day of the week), for example, "2.6 Saturday" for month 2, day 6, Saturday. The formal version is written as Day, Month, Year, for example" Day 6, Month 2, Year 1.

During one's birthday, gifting an item to the character usually will yield a higher or lower relationship value, as he or she will react greatly to it.

Notes can be added to each individual calendar day. To input a note onto the calendar, an icon resembling a notepad is found on the bottom right of the calendar page. These notes can serve as an event reminder, capable of reminding the player of an upcoming event, such as a fireside meeting. A time can be added to help remind the player of the event, which is formatted in 24-hour. In the event the player no longer needs the reminder, the reminder can be deleted.
