We built an uncomplicated calendar tool for low-fidelity planning
My partner and I do a lot of planning around things like holidays and trips, which involves a mix of firm, tentative, and overlapping plans, and normal calendars are the wrong fidelity for that kind of planning. We often found ourselves drawing on top of screenshots of calendars with tools like Miro or even printing out calendars we could draw on. We're both product designers, and so we're used to working in low fidelity tools like Excalidraw and FigJam. We decided to try and make a low-fidelity equivalent for calendars, and built Walnut.

Inspired by Minimal[1] and Netnik[2] printable calendars, I wanted a way to fit as many habits on a single sheet of paper as possible. This is very much a work-in-progress, so beware of bugs. I will flush it out over the next few days. Happy New Year, everyone! [1] https://useminimal.com/habit-tracker [2] https://neatnik.net/calendar/

A Minimal Monthly Task Planner (printable, offline, no signup)Dec 2025 · printcalendar.top · ▲94Hi HN, I built a tiny tool because I couldn’t find a clean, distraction-free monthly planner that: 1. shows a clean monthly task view 2. doesn’t require an account 3. doesn’t sync or store anything online 4. works offline 5. is printable 6. and keeps a minimal, distraction-free aesthetic So I made https://printcalendar.top/ — a minimal monthly task planner. It’s intentionally simple. No logins, no integrations, no dashboards. Just a small tool for people who want structure without clutter.

Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
