This module exist only for backwards compatibility issues with
earlier Pike releases. Use the Calendar module instead.
This code can be used to simulate the old calendar
for now (it might be removed in later Pike's):
This module has been totally rewritten in Pike 7.1+.
To be forward compatible the lazy way, you can do
something like this, though:
#if constant(Calendar.II)
#define Calendar Calendar_I
#endif
... import Calendar or whatever ...
This module implements calendar calculations, and base classes
for time units.
Calendar.YMD.Year()->week()
