Description

This is a parameterized implementation of a proleptic Gregorian Calendar that can be used in the creation of date systems or just to perform calculations. All the methods of this class are static functions, so the intent is to never create instances of this class.

Template Parameters

```
typename ymd_type_
```
Struct type representing the year, month, day. The ymd_type must define a of types for the year, month, and day. These types need to be arithmetic types.
```
typename date_int_type_
```
Underlying type for the date count. Must be an arithmetic type.
