Description

It was suggested in the Groovy-users thread to use dates (calendar.getTime) and use that for the range. I think that it would be better to stick to the Calendar objects and methods, since Date is deprecated and Calendar implements correctly Timezones and different Calendars, I think there were issues timezones and calendars in Date.

Implementation suggestion, credit Tim Yates:

http://groovyconsole.appspot.com/edit/44001

def startcal = new GregorianCalendar( 2009, Calendar.NOVEMBER, 1 )
def endcal   = new GregorianCalendar( 2009, Calendar.DECEMBER, 1 )

Calendar.metaClass.next = {
  Calendar c = delegate.clone()
  c.add( Calendar.DAY_OF_MONTH, 1 )
  return c
}

Calendar.metaClass.previous = {
  Calendar c = delegate.clone()
  c.add( Calendar.DAY_OF_MONTH, -1 )
  return c
}

(startcal..endcal).each {
  println it.time
}
