	Name	Description
	FIRST_ALLOWED_EXCEL_DATE	First date that can be displayed by Excel. Real values before this date cannot be processed.
	FIRST_VALID_EXCEL_DATE	All dates before this date are shifted in Excel by -1.0, since Excel assumes wrongly that the year 1900 is a leap year. See also: https://docs.microsoft.com/en-us/office/troubleshoot/excel/wrongly-assumes-1900-is-leap-year

The invariant culture (represents mostly the US numbering scheme) ensures that no culture-specific punctuations are used when converting numbers to strings, This is especially important for OOXML number values See also: https://docs.microsoft.com/en-us/dotnet/api/system.globalization.cultureinfo.invariantculture?view=net-5.0
