Thunderbird's Calendar Gets a Modern Makeover

Jesse from the Thunderbird design team recounts the journey to redesign the desktop calendar, aiming to modernize its look and streamline its functionality. The new design features a central grid, a navigation bar, and a collapsible sidebar for managing calendars. Early successes include updated event dialogs, and the team is now seeking community feedback as they move from design to implementation.

The future of calendar is wide open, and much brighter and less gray than the bygone era.

    Still no calendar where “today” is visually distinct. It has the same faded background as a multi-hour event.

    Look,at the header image and glance in the middle of the Wednesday column vs the middle of Sunday’s or Monday’s column. Very little visual distinction: you have to ask, am I looking at a long event or the ‘today’ highlight?

    Personally, I like the Google design and I bet most users will be familiar with. It works. Do not reinvent the wheel and just make it efficient.

    About ten years late to mimic Google Calendar. Was hoping for something new.

    Fantastical, Readdle and Apple Calendar have slightly fresher UI that could be good inspiration.
