I put up version 1.1 of the Calendar mod. The updated version is available at the same link:
Calendar ModThere are instructions in the Readme.txt on how to update from version 1.0 to 1.1. There isn't that much to do: Replace Calendar.php, couple changes to ModSettings.php, add the prompts to <language>.lng and the database changes.
Changes:
Added a title to the calendar so it won't show up as the URL in the browser's title bar.
Changed the way the Current Day is displayed. Does it like vBulletin does it. This looks differnet in all the browsers. Looks good in IE, looks sorta right in Netscape, but the colors are a little dark. In Opera it appears as a black outline around the day.
Removed all the prompts from the source and placed in language file.
Added some color selections to the Mod Settings screen.
Added holidays. There are a bunch of sample holidays in the Readme.txt file. By default there is no prompt in the calendar for the holidays (like "Events:" or "Birthdays:"), but if you want one, you can add it in the <language>.lng file (there's a comment in the .lng file).
Used vorapoap's idea to use short month names in the Prev/next links.
