Calendar
A calendar variable type represents an ODSL Calendar. It is used with timeseries, curves and other time-bound resources. See here for more detailed information on ODSL Calendars
Introduction
The calendar variable wraps a standard ODSL calendar and allows you to use the calendar in your scripts.
Construction
Calendars are usually read from the Calendar Service and referenced using their code, e.g. “business”, but some basic calendars can be constructed as follows:
// Create a daily calendar
daily = DailyCalendar()
// Create a business (Monday to Friday) calendar
business = BusinessCalendar()
// Create an empty holiday calendar
holiday = HolidayCalendar()
// Create a monthly calendar
monthly = MonthlyCalendar()
// Create an hourly calendar
hourly = IntradayCalendar(1h)
/**
Create an hourly calendar using a holiday calendar and
exclude hours 0-6 and 20-23
**/
peak = IntradayCalendar(1h, holiday, [0,1,2,3,4,5,6,20,21,22,23])
