A Dataview script for displaying an "On this Day" feature in Obsidian. Read more here: https://obsidian.rocks/supercharge-your-daily-notes-in-obsidian/

on-this-day.js

```dataviewjs
// update path and minyear if needed
const journalPath = 'Journal/Daily';
const minYear = 2012;

const d = new Date();
const rangeOfYears = (start, end) => Array(end - start + 1) .fill(start).map((year, index) => year + index);
const availableYears = rangeOfYears(minYear, d.getYear() + 1900);

const month = ("0" + (d.getMonth() + 1)).slice(-2);
const day = ("0" + (d.getDate())).slice(-2);
const dateString = month + '-' + day;

availableYears.forEach((y) => {
	// you may also have to update this date string, if your files aren't formatted in the default way (YYYY-MM-DD)
	var note = dv.page(`${journalPath}/${dateString}-${y}`);
	if (note) {
		dv.el('span', `[[${note.file.path}|${y}]] `);
	}
});

```

When using in the daily note files directly:

To have this in historic files as well and not bound to the current date, we can use:

dv.current().file.name

This will return the current file name, which we can use to extract month + day to then look up differnt years.
