Collating entries in my Obsidian journal for week notes
=======================================================

Published: December 14, 2025

Following up on my Mastodon post about wanting to start doing week notes, inspired by Ankur and Abhinav, here’s the quick rundown of how I supplemented my existing Obsidian journal to facilitate the new endeavor.

I currently use obsidian-periodic-notes to manage my daily notes and have mostly left the weekly/monthly option untouched, until now.

To actually collect the necessary journal entries, I relied on Dataview which I’ve used previously to get good at Marvel Snap. I wanted to minimize the changes I needed to make in my day-to-day workflow so I started with the restriction that at most I would be willing to tack on #weekly at the end of a journal entry that was noteworthy.

Dataview was able to beautifully navigate this limitation and with a little bit of JavaScript I now have a template that I can plug into Periodic Notes and get a roundup of the whole week in one click. Here’s how it looks with just today’s entries highlighted:

The relevant DataViewJS code is this:

(() => { const TAG = "#weekly"; const m = dv.current().file.name.match(/^(\d{4})-W(\d{2})$/); if (!m) { dv.paragraph("Weekly note filename must be like `2025-W50.md`."); return; } function isoWeekStartISO(year, week) { // Compute ISO week start (Monday) in UTC, then return YYYY-MM-DD const simple = new Date(Date.UTC(year, 0, 1 + (week - 1) * 7)); const dow = simple.getUTCDay(); // 0..6, Sun..Sat const start = new Date(simple); if (dow <= 4) start.setUTCDate(simple.getUTCDate() - dow + 1); else start.setUTCDate(simple.getUTCDate() + (8 - dow)); // YYYY-MM-DD return start.toISOString().slice(0, 10); } const year = Number(m[1]); const week = Number(m[2]); const start = dv.date(isoWeekStartISO(year, week)); const end = start.plus({ days: 7 }); const pages = dv.pages('"Daily"') .where(p => p.file.day && p.file.day >= start && p.file.day < end) .sort(p => p.file.day, "asc"); let any = false; for (const p of pages) { const bullets = (p.file.lists ?? []).filter(li => (li.text ?? "").includes(TAG)); if (!bullets.length) continue; any = true; // [[YYYY-MM-DD]] dv.paragraph(p.file.link.toString()); // - Line 1 // - Line 2 dv.list( bullets .map(li => li.text ?? "") .map(t => t.replace(TAG, "").replace(/\s+/g, " ").trim()) .filter(Boolean) ); dv.paragraph(""); } if (!any) dv.paragraph(`No ${TAG} bullets found for ${m[1]}-W${m[2]}.`); })();

The code is relatively simple: It finds the week number from the current file name, gathers the range of dates for that week, inspects each file for lines that contain #weekly, and then neatly lays them out grouped by date.
