I thought it was awesome that Ubuntu 16.04 shipped with gnome-calendar, but I noticed that holidays were not included. I also noticed that there is an option to sync the calendar with an online one, how do I do this? I don't know of any online calendars I could use.
You can achieve that using the
gnome control center in Ubuntu:
dash, settings will appear select that and select
Then add your google account by clicking the plus sign at the bottom of the dialogue window that appears:
Then turn the calendar associated with that gmail account on, and this should sync it with Ubuntu Calendar.:
If you want more Calendars set it up in Calendar in google from the
settings optionstop right corner of calendar page.
Google has changed how apps communicate with your google account so you have to setup your phone from here else you won't be able to add an account.
SETUP GOOGLE ACCOUNT CALENDAR SYNC
Go to google calendar:
settings, top right of page:
In ther click on the
Calendars tab, top left of page:
In there click on
That will export your calendar in a
.icsfile format. Now Lets instruct
Calendarto sync back in Ubuntu desktop.
INSTRUCT CALENDAR TO SYNC WITH DOWNLOADED
Extract the downloaded
Calendarand click on
Form the dialogue box that appears select
Navigate to that extracted
.icsfile location, select it and choose the one without the #[tag] at the start of the name.
Back in Calendar select
synchronizeand make sure your internet is working and after a few minutes your synced calendars will appear.
To get all my Google calendars to sync, I had to go enable syncing them in a hidden Google sync settings page:
Then I had to disable Calendar for my Google account in Gnome Online Accounts settings, and re-enable it. After that all my calendars are synced.
The same is actually needed for the Windows 10 Calendar, which is how I found it.
For me, there was a bug with the gnome-calendar app where I could not click the "Add" button (the one in your screenshot), no matter what I entered.
I found a workaround by using the way the GOA (Gnome Online Accounts) works:
- Download "Evolution" from the official repositories.
- Add your online Calendar to Evolution. (Guides for adding several kinds of calendars to Evolution: help.gnome.org)
- Verify that your appointments etc. are shown in the gnome-calendar app.
- Uninstall Evolution. (If you do that, there is probably no way to reconfigure the calendar, so you could also just leave it as it is but still use the gnome-calendar app.)
In short, since Evolution also uses the GOA, just like gnome-calendar does, any calendar that you add there will also be added to gnome-calendar. The same should in theory apply for every other app that uses the GOA.
Regarding which calendar you should use, it depends. Holidays can be very different in different locations or even schools, so you need to find a source for yourself.
In general you have two options of adding holidays to gnome-calendar: Import an offline file (.ics) or the one I described above. Using one of the providers from the GOA Menu, like Google, Nextcloud or Microsoft Exchange is just a bit easier than importing a calendar from a custom provider.

I think ubuntu 17.10 and 18.04 do not sync the Gnome Calendar with google calendar automatically.
I would suggest, since Evolution Mail treats the Gnome Contacts and Calendar, that you install Evolution with the important file evolution-data-server. Then you have to configure the google account within the Evolution Calendar. Some pictures of this operation were shown upstairs.
In the settings it is possible to choose even the important option "sync time" (the default 30 min is for me too much so I set it to 1 min) which is the time lapse between every synchronization. Finally you can see all Google events in the Gnome Calendar in the top bar. After these operations you can remove Evolution Mail but not evolution-data-server which is necessary to do the sync.
Note: you have to do this operation if you want to use Thunderbird and not Evolution Mail. Thunderbird is the default application in Ubuntu 18.04.
