Holidays

Array of holidays, each defined as follows.

IsoCountry

Two-letter ISO code of the country.

MonthNumber

Number of month - use 99 for relative dates using Easter as a reference.

DayNumber

Absolute day (ignore WeekDayNumber when other than 0).

WeekDayNumber

Day of the week, as a number:

• 0 : Sunday
• 1 : Monday
• 2 : Tuesday
• 3 : Wednesday
• 4 : Thursday
• 5 : Friday
• 6 : Saturday

OffsetWeek

Number of the week in the month, negative if the reference is the last one in the month

• 1 : first week
• 2 : second week
• …
• -2 : second-last week
• -1 : last week

OffsetDays

Days to add after OffsetWeek and WeekDayNumber have been applied.

HolidayName

Name of the holiday.

SubstituteHoliday

Define the logic to move an holiday to another day in case the date is already a non-working day (e.g. “in lieu of…”)

• NoSubstituteHoliday (0): no substitution.
• SubstituteHolidayWithNextWorkingDay (1): substitute the holiday with the next working day.
• SubstituteHolidayWithNextNextWorkingDay (2): substitute the holiday with the second next working day. Use only for the holiday immediately before another holiday marked with SubstituteHolidayWithNextWorkingDay. For example, use SubstituteHolidayWithNextNextWorkingDay for Christmas and SubstituteHolidayWithNextWorkingDay for Boxing Day.
• FridayIfSaturdayOrMondayIfSunday (-1): if the holidays falls on a Saturday then it is observed on Friday; if it falls on a Sunday then it is observed on Monday.

ConflictPriority

Priority in case of two or more holidays in the same date. A lower number corresponds to an higher priority.

For example, marking Easter relative days with 150 and other holidays with 100 means that other holidays take precedence over Easter-related days; use 50 for Easter related holidays to invert such a priority.

FirstYear

First year for the holiday, 0 if it is not defined.

LastYear

Last year for the holiday, 0 if it is not defined.
