Unless you specifically choose "Month" you cannot actually see a summary of the entire month next to another view (eg "Week" or "Day") and there is literally no Fortnight view - oh, and you cannot limit a day to only show, say, Business Hours (9-5) or whatever.
You get a notification popup and click on it... NOTHING HAPPENS - and the little badge next to the icon in the dock NEVER UPDATES - it still shows events from LAST MONTH!
No support yet for WebCal, such as those offered by Facebook events.
A workaround exists. Since this application uses the same background services as Evolution, installing it and adding the WebCal calendars there, also adds them to GNOME Calendar.
The GNOME Calendar displays pop-ups from an old Google Calendar that was used. That Google Calendar has long since been removed from GNOME, and even with the notifications turned off on the GNOME Calendar, the pop-ups still happen.
Through the Google Calendar's web client, it is possible to subscribe to any public calendar. Google also maintains a list of public calendars for various sports events and holidays in different countries and for different religions.
All views have an option of adding a new event by tapping the plus sign at the lower right corner of the screen. This opens up a form and allows the user to add a location, start/end times, guests, description, color-code as well as choosing if it's an all day event, how often it repeats, how many and what kind of reminders are needed and setting the users availability and privacy settings.
Google Calendar has a monochrome base design that's accented with colored-coded events and image banners that separate months in schedule view.
The app has 5 different views - schedule, day, 3-day, week and month.
Day, 3-day and week views split up the days horizontally and hours vertically. Month view lays out all days in a grid and displays up to 3 events in a day.
Schedule view displays an agenda view that allows browsing all events by swiping vertically. Additionally, the way events are displayed in the agenda view is context-aware. For example, adding an event called "gym" will display the event on a background with a dumbbell.
All views except for month view can be split horizontally to display a condensed month view at the top that can be navigated by swiping horizontally.
Events can be added from any view by clicking the red plus button that's available at the bottom-right corner of the screen.
Google Calendar integrates with e-mail for quickly creating events from e-mails that contain the word "meeting" or dates or times, or any other information about events or plans that it can understand.
Google calendar allows setting how many reminders are needed with each having the ability to set how long before the event the notification should remind and if it should be done via on-screen or e-mail notification.
Whenever you enter agenda / event title with the keywords (when available), the event will show up interesting flairs whenever the keyword inside the agenda / title you typed matches the flairs that are available inside the system, examples such as haircut, cycling, swimming, coffee, movie etc.
Google Calendar can be integrated with any calendar that support iCalendar format, including Exchange and iCloud, via URL, but it has to be done using the web client.
The app doubles as a task manager and allows dragging and dropping tasks into the calendar on specific days. If a task does not get completed on that day, it automatically gets rescheduled.
Natural language input allows creating events in the same way if you had to tell it to a friend. Writing something like "Lunch at 2pm" would add an event called "Lunch" at 2 PM. SmartDay lacks that functionality.
