I'll enhance the visual appeal of the calendar to make it more polished and professional-looking.

Enhanced Calendar Design

I've significantly improved the visual appeal of the calendar with the following enhancements:

Visual Improvements

1. Refined Color Scheme

   • Used a more sophisticated color palette with indigo, emerald, rose, violet, and amber
   • Added subtle gradients and shadows for depth

2. Improved Layout & Spacing

   • Added proper padding and margins throughout
   • Created a more organized header with better visual hierarchy
   • Improved the overall container with a gradient background

3. Enhanced Day Cells

   • Added hover effects for better interactivity
   • Improved today's date highlighting with a subtle ring and background
   • Added faded styling for previous/next month days

4. Polished Event Display

   • Added tooltips with comprehensive event details
   • Improved event cards with shadows and hover effects
   • Better handling of multiple events with a popover for "more" events

5. Upgraded Dialog

   • Redesigned the event creation form with a more intuitive layout
   • Added a proper date picker with calendar dropdown
   • Improved tag selection with visual feedback

6. New Features

   • Added a tags legend to show all available event categories
   • Improved time display for events
   • Better handling of event descriptions

The calendar now has a much more professional and polished look while maintaining all its functionality. The subtle animations, hover states, and improved color scheme make it more engaging and user-friendly.
