Date for health note (Read 528 times)

Today I entered a new health note. I use the european default date format of dd/mm/yyyy. I checked that format was showing (which it was) and then entered 06/05/2007. But it put my health note on 5th June. So I went back to edit and checked again that it was showing the correct format. I then had to enter 05/06/2007 to get it to put the health note in May. I'm using Windows XP SP2 and Firefox 1.5.0.11
