Drupal calendar issues
Here's the fix, the reference to it is here : click on this link and scroll down to item #20 : drupal.org/node/2294973 , however its pasted below just in case that link becomes broken...

Quick workaround for people unable to apply the patch:

STEP 1: Edit date_views/theme/theme.inc and go find line 165.

Change these two lines:

$format_with_year = variable_get('date_views_' . $granularity . 'format_with_year', 'l, F j, Y');
$format_without_year = variable_get('date_views_' . $granularity . 'format_without_year', 'l, F j');


To these two lines:

$format_with_year = variable_get('date_views_' . $granularity . '_format_with_year', 'l, F j, Y');
$format_without_year = variable_get('date_views_' . $granularity . '_format_without_year', 'l, F j');


Note: the only difference is one underscore character added to each line.

Upload the changed file back to your web server.

STEP 2: Go to (YOUR_WEBSITE)/admin/config/regional/date-time/date-views and click Save. If you get permissions errors, try clearing caches.
