/**

 * additional useful functions related to the calendar. By default, these calendars
 * have Monday as the first day of the week, and Sunday as the last (the European
 * convention). Use setfirstweekday() to set the first day of the week to Sunday
 * (6) or to any other weekday. Parameters that specify dates are given as integers.
