Once you have one-off Services or one-off Events which are which are upcoming and are tagged with the Christmas tags, and you've enabled the National Campaigns option for your church, the View Christmas Services button will appear on your church's homepage:
and the Advent & Christmas section will appear on your Services and Events page
Christmas and Advent Services and Events are added in the same way as you add standard one-off Services and Events. To make sure the Service or Event is listed in the Christmas & Advent Section, remember to use the Christmas-related tags available in the tag section. At this time, only one-off Services and Events will appear in the Advent & Christmas tab. Click all the tags that are related to your Service or Event - there is no limit to the number of tags you can add.
Make sure you enable the National Campaigns option to ensure you get the Christmas button on your homepage, here's how to do it:
Once you’re logged in, go the pencil next to the name of your church on the left-hand side. This is where you edit your Page Content information and add profile, logo and cover pictures.
Scroll down the page to the section called ‘Campaigns’.
Select the campaign you wish to apply to your page by clicking the tick box, then scroll down the page and click ‘Save’.
