Note: This is if you have access to Vivaldi Webmail

You can also go to Vivaldi Webmail site, click on Calendar in the panel on the left, click on Import on the bar above the calendar

and Choose the file, the already created calendar and how old the imported events will be Untitled.jpg

@frenzzgoa you can also add a Google calendar as an online calendar, where events get synced (if you import .ics files, that's static/unsynced. See the help files in the section about Google calendar accounts here https://help.vivaldi.com/calendar/calendar-get-started/add-and-manage-calendar-accounts/#Online_accounts

@DoctorG Yea. I just opened calendar and i had like 8 calendars. I think it was what you said. Thank you

Good ... You understand that the developers' fresh installed version will work. We are basing everything on an already functioning process. I would like to remind you once again that I have been using the calendar with CalDav synchronization for a couple of years. At some point (around 7-8 versions ago), all the entries disappeared. I didn't create a ticket because I thought it was a widespread issue. Now the entries have reappeared, but they are duplicated. Let's proceed from what we have. I can provide some logs or diagnostic dumps specifically related to my problem. Again, it is quite possible that this issue is related to the mail.ru service itself.

@AECLx3015 Added as bug VB-116347

@Patrick31150 DoctorG is correct, Vivaldi will only sync every 10 minutes. You can also trigger manual sync if you need faster update, in the main calendar view click the Calendars button in top bar and Refresh command there.

Google calendar can update instantly because they have the server and can push the update to the web client right away. CalDAV protocol does not have a persistent connection or push mechanism. Only by polling can clients know of new events. And polling too frequently causes a lot of traffic so we have to have some middle ground. We have considered polling more frequently if the calendar is open and active and then delay longer when calendar is inactive which may make it feel quicker, but it is not implemented yet.

@eggert I have done some tests, unfortunately with bad news.
There are some more problems with the caldav sync @ t-online:
At first and for sure: An event created on vivaldi appears one day earlier on t-online.
Further tests led to somewhat confusing results.
Sometimes, after a while without any further action, this event disappears on vivaldi, but not on t-online. I got it back using a manual sync call. From time to time I got error messages like these:
1b4d3803-c864-4c4f-997a-273eed3329c7-image.png
In my opinion, the error with the multiplication of events does not always occur. But it is difficult to carry out structured tests with all these sync errors.

Is there a way to do this via CSS?

I'll file a request for enhancement because I think this is a usability adn accessibility issue.

Usability: if I set a custom color in local vivaldi options (and it is displayed until the calender is refreshed) it should prevail on whatever color the remote calendar has.

Accessibility: same as above but with the need for some people to change the color due to eye impairness or illness. I'm photophobic and that orange is really hurting my eyes.

Edit: I've filed VB-116164

@stereiss This is not configurable for now. It has been for quite some time on our list of things to do to make a more traditional fixed size view but it has not been done yet.

I am seeing issues with this also.
The solution imho is not far. It is to always send invitations with the time zone I am in and receive invitations THEY are in. That is - if I see it right - the case with version 7 of Vivaldi calendar. So far so good for Vivaldi.
The issue for me is, that an event I receive from Kenya (EAT) will be shown in my calendar in EAT time allthough my time zone is CET. That means confusion.
When I click on the event, I can see that vivaldi recognizes the time zone EAT but does not automatically convert it to my calendar view, which is in CET.
Am I missing a configuration setting?

@mib2berlin The difficulty I'm having is I'm not trying to get my Google calendar to show up in Vivaldi, I'm trying to get my Vivaldi calendar to show up in Google.

Details on our setup: https://docs.gwdg.de/doku.php?id=de:services:email_collaboration:davmail:start

@Loranh Please report issue to Vivaldi bug tracker, include as much detail as possible.
Once that is done, share the bug number (beginning with VB-) you got by bug report mail.

And if interested read blog article, if you like to know about "A bug’s life at Vivaldi".

Thanks for helping us making Vivaldi better.

@stereiss Either way is fine really. If you are unsure about anything just throw a question in here, there are a lot of helpful users, as well as our ambassadors and moderators who can help with many issues and if not have some access to devs to poke them.
Or as a feature request if you know what you want to do is not possible. Please do a search first to see if it is already covered by another request you can upvote. We do our best to follow up on those and upvotes are considered as well.

And any help we can get to spread the word about Vivaldi is invaluable to us 🙂

For in formation, I just kept this year in my calendar (242 items). I removed the calendar in Vival, reinport it, and I have the same error :
14:34:43.788 error [Calendar - sync, parser] Error getting event from server for calendar 46. 404 {"href":"/dav/XXXX@XXXXXXCalendar/","status":404,"getcontenttype":{"status":404,"value":""},"resourcetype":{"status":200,"value":["d_collection","c_calendar"]},"getetag":{"status":200,"value":"3244292-1"}}

Hi @guckuck and thanks for the report.

Do you know if the nextcloud server has an extension called Deck installed? It creates some calendars (for all users it seems whether or not they use it) which behave a little different from the regular calendars and cause this error. The decks don't work in Vivaldi either but that seems to be the case for other clients as well at least for the most part.

Thanks. The bug number VB-115672.

@mib2berlin yes humans do, but the bot crawlers that just scan whatever pages they find just look for mail addresses to fill databases.

@yojimbo274064400 wow, awesome spotting skills!

@odnes good to hear that you feel comfortable using Vivaldi's Mail/Feeds/Calendar feature now. Please feel welcome to give your feedback or ask questions. Welcome to the forum!
