However, if the date did not really change: {{{ form.initial = {'mydate': '2013-01-15'} form.data = {'mydate': '01/15/2013'} }}} 'mydate' will show up in form.changed_data, because widgets.DateInput._format_value can only use one format, there's no way to make the widget recognize multiple formats.",Bug,closed,Forms,1.5,Normal,worksforme,,,Unreviewed,0,0,0,0,0,0
