Struct calendrical_calculations::rata_die::RataDie

source ·
pub struct RataDie(/* private fields */);
Expand description

The Rata Die, or R.D., or fixed_date: number of days since January 1, 1 CE.

See: https://en.wikipedia.org/wiki/Rata_Die

It is a logic error to construct a RataDie except from a date that is in range of one of the official calendars.
