Description:

Replaces RimWorld’s 4-quadrum (60-day) year with the Earth’s 12-month Gregorian calendar (365/366 days per year).

Features:
– Earth month names (January through December) with correct month lengths and leap years
– Pawn ages and dates shown using the Gregorian year
– Fixed pawn generation so adults spawn with correct ages
– Birthday display for each pawn showing month, day, and year
– Quadrum system replaced by 12 months in UI readouts where applicable
– Hemisphere-aware seasons (northern/southern hemisphere differences)
– Seasonal temperature progression paced over 365/366 days; Fahrenheit and Celsius shown together or individually
– World tile climate graph of monthly average temperatures
– Growing period readout scaled to a 365/366-day year (not 60)
– Configurable scaling for aging, plant growth, animal yields, research, etc.

The mod provides a familiar calendar while preserving RimWorld’s game-play balance.

It is not safe to add to a save. (For a rule of thumb, you should almost never do that)

Mod Incompatibilities:

Mod Incompatibilities/Bugs I’m looking into:
RimHud works fine, but displays incorrect biological age (My mod recognizes the correct one and corrects the age)

Mods That Magically Started Working Again?:
Dubs Rimatomics

Future Updates:
Cleaning up UI and other uses of Quadrums

Future Work:
Custom Months and Year lengths.
Variable Distance From Sun and Other Astrophysical Statistics
