fn is_holiday(&self, date: T) -> bool

fn is_bday(&self, date: T) -> bool

Adjusts date to the last/next business day if it’s not a business day.

fn advance_bdays(&self, date: T, bdays_count: i32) -> T

Advances bdays_count number of business days from date.

fn bdays(&self, d0: T, d1: T) -> i32

Returns the number of business days between d0 and d1.

Implementations on Foreign Types

impl<T: Datelike + Copy + PartialOrd> HolidayCalendar<T> for Vec<GermanState>

This implementation considers a date a holiday if it is a holiday in any State in the Vec. See the implementation for GermanState for details.

fn is_holiday(&self, date: T) -> bool

Implementors

impl<T: Datelike + Copy + PartialOrd + Display> HolidayCalendar<T> for HolidayCalendarCache<T>

impl<T: Datelike + Copy + PartialOrd> HolidayCalendar<T> for GermanState

This implementation doesn’t return any holidays before 1990.

Before that the current Germany was separated into the “German Democratic Republic” and the “Federal Republic of Germany” which both had somewhat different holidays. Since this class is called “Germany” it doesn’t really make sense to include the days from the two former countries.

Note that Germany doesn’t have rules for holidays that happen on a Sunday. Those holidays are still holiday days but there is no additional day to make up for the “lost” day.

Also note that German holidays are partly declared by each state there are some weired edge cases:

• Assumption Day / Mariä Himmelfahrt is only a holiday in Bavaria (BY) if your municipality is mostly catholic which in term depends on census data. Since we don’t have this data but most municipalities in Bavaria are mostly catholic, we count that as holiday for whole Bavaria.
• There is an Augsburg Peace Festival / Augsburger Friedensfest which only exists in the Bavarian town Augsburg. This is excluded for Bavaria.
• Maundy Thursday / Gründonnerstag (Thursday before easter) is not a holiday but pupils in Baden Württemberg (BW) don’t have to go to school. It is excluded from our list.
• Corpus Christi / Fronleichnam is a holiday in certain, explicitly defined municipalities in Saxony (SN) and Thuringia (TH). We exclude it from both provinces.
