Turn Date into Year format (Buch Template)

Help
1

What I’m trying to do

Additionally to the published date, I like to list the published year. However, non of the formatting hints is working.

<%“—”%>
tag: Buch
title: “{{title}}”
subtitle: “{{subtitle}}”
author: [{{author}}]
category: [{{category}}]
publisher: {{publisher}}
publish: {{publishDate}}
year: {{publishDate}}
total: {{totalPage}}
isbn: {{isbn10}} {{isbn13}}
cover: {{coverUrl}}
status: unread
categories: books
<%“—”%>

Things I have tried

I tried to add something like this without succeeding.

publishDate:Year

year().format(„YYYY“)

Thanks for helping!

Tried with what? Are you referring to a template plugin, or something else? (Pardon if it’s obvious to someone else.)

Maybe the tool/template you are using doesn’t support the „“ and might need to be "". But I’m just guessing.

You are right: I edited the Buch template in Obsidian itself. Adding new fields was no issue at all, but the time format for year only is a challenge for me.

First step succeeding, but mapping on variable „year“ doesn’t work.

published_at: <%= book.publishDate.substring(0, 4) %>

year:
