Concepts

Validation and calculation functionality is accomplished by retrieving an annual calendar and a holiday calendar (both retrieved by a calendarId) to determine non-working days. Both calendars are stored as Dynamic Processing Settings (DPS).

An Annual Calendar holds configuration of weekends (if applicable) and also defines which days are excluded business days when such days fall on the same date every year (e.g. Christmas Day and Gregorian New Year’s).

A Holiday Calendar excludes specific dates where day, month and year are taken into account. This is useful for moving Bank Holidays (e.g. President’s Day) and movable feasts (e.g. Easter, which is based on the lunar calendar).
