calendar width

How can I change the width of the calender view?

It is a little too big for my site:
integralzen.de/event-kalender.html?month=10&year=2017&next=1

Thx,
Stefan

I changed the page layout (removed the left column that is there on all other pages (except hompage), but the calendar is still too big!

Hi Stefan

Might causes by some conflict with css of your site template. Please submit a support ticket sending us super admin account of your site so that our template developer can help checking and solving it for you

You should consider purchasing new license to use latest version if it is possible as your support perior was expired few months ago (and look like this is another new site from you if I remember correctly).

We will still help with this issue even if you don't purchase new license, so just submit a support ticket. Our developer will check it tonight or on tomorrow
