Data precision

There is no generally valid designation for the next administrative level of countries. "Nager.Date" supports the initial subdivision of a country, but we will not support a detailed level because the effort required is too high.

To keep it generally valid, we will treat this subdivision as SubdivisionCodes, this will replace the current designation Counties.

• United States of America use States
• Germany use States
• Austria use States
• Switzerland use Cantons
• Brazil use States
• Australia use States or Territories
• Russia use Federal districts
• Canada use Province or Territories

Precision	Supported
Public Holidays for specific Country	Yes
Holidays for Subdivisions based on ISO 3166-2 (first level)	Yes
Holidays for Cities	No
Holidays for Regions	No
