MoinMoin: attachment:CalDate_0.1.py of MacroMarket/CalDate

   1 # To use this macro, place in a page which is under a calendar:
   2 #   <<CalDate("%d %B %Y")>>
   3 # If it's under a calendar which has the date "2004-10-28",
   4 # it will render as "28 October, 2004".  It also allows you
   5 # to use:
   6 #   <<CalDate("%d %B %Y",7)>>
   7 # This will advance the output by 7 days.  So you get
   8 # "4 November, 2004".  I use this on my chorus rehearsal
   9 # notes page where I want to have a section describing the
  10 # last rehearsal, and then a section describing the upcoming
  11 # rehearsal.
