# Gregorian Calendar

### &#x20;*<mark style="color:yellow;">Soon to be added to AdvancedSeasons!</mark>*

In the upcoming release of AdvancedSeasons, a new **Gregorian Calendar** feature will be available, providing an option to choose between **CUSTOM** and **GREGORIAN** calendar types for your Minecraft world. Here's what each calendar type offers:

* **GREGORIAN Calendar**: This type follows the traditional 365-day format, allowing you to define when each season starts within the calendar year. It provides a more realistic simulation of real-world seasons but restricts any modification of the total number of days in a year.
* **CUSTOM Calendar**: This option gives you full flexibility to determine the total number of days based on the sum of the **seasonDays** and **transitionDays** (typically covering four seasons). It allows for custom configurations suited for game mechanics.
