Google launched a redesigned version of Google Calendar on the web today. The calendar looks way more modern with larger date icons, updated colors, and cleaner event boxes. It basically looks more like the mobile application.
As for functionality, Google focuses on improvements for business users. Admins can now add details about conference rooms, so employees know how large they are, whether they’re wheelchair accessible, and whether they have AV equipment. People can also link to spreadsheets, documents, and presentations in their calendar invites so attendees can open them directly from the "event detail" view. You can get an idea of that here:
Google also incorporated a bunch of smaller changes that might be impactful if you're in your calendar a lot or often coordinate with other people. Users can now view multiple calendars on the "day" view, for easier comparison and booking. They can also hover over participants' names to view their contact information.
None of these adjustments are life-changing, but they're useful. Plus, it's always nice to look at something pretty.
