The calendar interface is accessed from the player's inventory with the tab that has an hourglass symbol.
Each season spans over three months, with "Early" being the first month and "Late" being the last month. Seasons are reversed south of the equator with the middle of winter in July and the middle of summer in January.
Season determines the current ambient temperature of an area, with temperatures being colder in the winter and warmer in the summer. During the colder seasons tree leaves can change color, and fruit trees will not grow new branches or leaf blocks. Berry Bushes and fruit trees only provide fruit during specific seasons depending on the type.
In addition to the seven days of the week, the calendar will display the birthdays of the developers. Kitty's birthday will only appear if the config has been changed with a custom year length.
- June 18 - Kitty's Birthday
- July 7 - Bioxx's Birthday
- October 2 - Dunk's Birthday
Newly generated worlds always start in the year 1000, on the first of June. By default, each month consists of 8 days for a total year length of 96 days.
The calendar uses military time to display the current in-game hour, with "The Witching Hour" being displayed for the final hour of the day. Although sleeping in a bed still wakes the player up at 6 o'clock in the morning, the visual sunrise and sunset is dependent on the latitude and the current date, daytime being longer in the summer and being shorter in the winter. In the equator, sunrise is at 6 a.m. and sunset is at 6 p.m. no matter what date it is. Mob spawning is also dependent on local sunrise and sunset.
Fog will appear first thing in the morning and dissipate around noon.
