Latest news about Online and Mobile Calendars


2018. G Suite apps and Google Calendar are getting Gmail’s side panels



One of the best features of the new Gmail is its quick-access side panel with easy access to Google Calendar, Tasks, Keep and your Gmail extensions. Now, Google is bringing this same functionality to Google Calendar, Docs, Sheets, Slides and Drawings, too. In Google Calendar, you’ll be able to quickly access Keep and Tasks, while in the rest of the G Suite apps, you’ll get easy access to Calendar, Keep and Tasks. Paying G Suite subscribers on the rapid release schedule should get access now, with those on the slower release schedule getting access in two weeks.


2018. Google Calendar gets an Out of Office mode



Google Calendar gets a new “Out of Office” feature along with setting customizable working hours. The working hours signal to others when you’re unavailable, and allows Google Calendar to automatically decline meetings on your behalf outside those hours. For starters, you’ll find there’s a new “Out of Office” calendar entry type you can select when you’re creating an event via Google Calendar on the web. For example, if you’re scheduling the dates of your vacation, you could mark that event as “Out of Office.” If others send you meeting invites during this period, Google Calendar will decline them without your involvement.




2018. Google Calendar now lets you add a message when you change an event



Google Calendar gets a new useful feature. When you change or delete an event, a dialog box now pops up that allows you to attach a short message to the event to explain why you are making the change and what’s changing. On the event page in Google Calendar itself — and in the email that alerts your guests of the change — that message will then appear at the top of the event details section. The new dialog box appears automatically, so far more people will now explain their changes than before. This new feature is now rolling out to all G Suite users and should be available to everybody (no matter whether their admins have them on the rapid release or schedule release schedule) within the next three days.


2017. Google redesigned Calendar for web



Google rolled out new updates for the web version of Google Calendar, finally giving PC users the sleek layout and intuitive controls offered on the mobile app version of the G Suite tool. The redesigned calendar layout will automatically adjusts to better fit the size of your screen. Most of the other features coming with the web redesign will be helpful for people using Calendar within wider organizations. The handiest of these will now allow you to check out multiple users' calendars side by side for a given day, in order to see how everyone's schedule lines up.  Calendar Invites now allow to add formatting and hyperlinks directly into the description field, and G Suite administrators will be able to include more details about conference rooms within an organization.


2017. Google Calendar improves integration with Microsoft Exchange



For companies that use both Google’s G Suite and it's Microsoft alternative - Exchange in parallel, the new Google Calendar update arrived. G Suite admins can now allow their users to see real-time free/busy information across the two systems. This means tools like Google Calendar’s Find a Time feature and Outlook’s Scheduling Assistant can now easily talk to each other, for example. Once an admin has enabled them, these new Calendar Interop features will be available on Google Calendar for Android, iOS and the web, as well as all Outlook 2010+ clients on desktop, mobile and web.
