Arguments

A vector (or scalar) of Date types.

Value

• An named vector of booleans each of which is true if the corresponding date is a business day in the given calendar. The element names are the dates (formatted as text in yyyy-mm-dd format).

Details

The calendars are coming from QuantLib, and the QuantLib documentation should be consulted for details.

Currently, the following strings are recognised: TARGET (a default calendar), Canada and Canada/Settlement, Canada/TSX, Germany and Germany/FrankfurtStockExchange, Germany/Settlement, Germany/Xetra, Germany/Eurex, Italy and Italy/Settlement, Italy/Exchange, Japan, UnitedKingdom and UnitedKingdom/Settlement, UnitedKingdom/Exchange, UnitedKingdom/Metals, UnitedStates and UnitedStates/Settlement, UnitedStates/NYSE, UnitedStates/GovernmentBond, UnitedStates/NERC.

(In case of multiples entries per country, the country default is listed right after the country itself. Using the shorter form is equivalent.)
