CMS Error help please

I am just starting a new project and have literally just started, I am getting an error that I do not know what is causing this. I have one page only, 1 md file only. I can not publish file here as it’s commercially sensitive.
I have the “collection” I am building rendering but I am getting a YAML error. Here is image of error and a copy of my simple code only. I do not want to start adding other bits to md file until I get rid of this error. TIA for your help @dan @ben.

You need to handle that through the Twig syntax.

For example, if your YAML frontmatter contains:

date: “2026-08-15” then using: {{ item.date }}

will naturally output the full date exactly as it is stored.

If you only want to display the year, you need to adjust your Twig syntax accordingly.

{{ item.date|date(“Y”) }}

This will output: 2026

THANKS I just have date: in my md file and I just had {{date}} in field. This was giving a dd/ymm/yyy output.
I have no dates any where in md file set up at all just name. I tried your code and I now get dd/mm/yyyy 00:00, TIA
