- Added timezone support (Pacific/Auckland) for calendar events - Implemented recurring event handling using recurring_ical_events library - Created horizontal 5-day column layout for calendar display - Fixed multi-day event rendering to show events across all active days - Updated calendar to show next 5 days (today + 4) - Reduced font sizes and padding for compact display - Changed image rotation interval to 60 seconds - Added pytz and recurring_ical_events dependencies Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
