RPG Setting Calendar Builder

Create a calendar for your RPG system or setting. You can either build it from scratch, or modify one of the preset calendars to suit your campaign. Once your calendar is built, you can view it in the Preview tab.

Your customized calendar can be shared with others. See the Share tab for details.

General

Calendar Name
Calendar Era		The abbreviation after the year that identifies the calednar's era or dating system.
Minimum Year		The earliest year the calendar is valid. Normally, this would be 1. This option is here specifically for the Gregorian calendar, as this system is not sophisticated enough to support the dual dating that was required as the Gregorian calendar was adopted.

Leap Years

Leap year rules are evaluated in order.

Astronomical Seasons

The are four astronomical seasons, defined in the order in which each equinox and solstice occurs (e.g., Spring, Summer, Autumn, Winter in the northern hemisphere) in the calendar year.

Season Name	Begins On
	northward (vernal) equinox
	northern solstice
	southward (autumnal) equinox
	southern solstice

	Full Name	Short Name	Days	Leap Month

	Full Name	Short Name	Abbrev	Founding Day

The order in which moons are defined is not significant.

Names can be assigned to the first full moon in each month. Enter these as a comma-separated list, corresponding to each month of the year

	Name	Period (days)	First Full Day	Color	Full Moon Names (comma-separated)

Holidays can be defined using the following rules:

• Nth day of Month (Example: January 1st)
• Nth Weekday of Month (Example: 1st Monday in September)
• Nth full week of Month (Example: First full week of April)
• Nth day of Season (Example: First day of Spring)
• First Phase of Moon in Month (Example: Full Moon of Luna in October)

Specify negative values for N to count from the end. (Example: "-1st Monday of January" would mean the last Monday in January).

Make sure your month, weekday, and moon definitions are complete before defining holidays! Changing the calendar structure can invalidate your holiday definitions. Note that definitions based on full moons can result in skipped holidays if the lunar period is longer than the month.
