Calendar widgets that actually update: lunar calendars, perpetual calendars and date trackers

Embed a live calendar in Notion, Obsidian or your website: perpetual calendars with lunar dates and holidays, traditional almanac calendars, minimal date cards and moon-phase calendars — real-time iframes, free to embed.

A calendar that doesn't update is a liability: every Monday it silently lies about what day it is. The calendar widgets below are live crops of real calendar pages — almanac sites, date tools and moon-phase trackers — so the grid you embed today is still correct next month, without you touching it.

Perpetual calendars with lunar dates

For pages that need the full almanac: lunar dates, solar terms, holidays and the traditional auspicious/inauspicious notes.

Month grids — the classic calendar card

  • Calendar with holidays (360) · embed: https://embed.widget.diy/CPppxfnt — a clean month grid with today highlighted and holidays marked.
  • Calendar (mumudroid) · embed: https://embed.widget.diy/dMRAF4f9 — today's date front and center, ideal for a dashboard header.
  • Calendar card · embed: https://embed.widget.diy/twNM25ho — a compact month view for sidebars.
  • Minimal calendar · embed: https://embed.widget.diy/47Kvypqp — date and month only, typography doing the work.

Moon-phase calendars — the sky's calendar

  • Moon-phase calendar · embed: https://embed.widget.diy/xtoEhuy4 — today's date beside the current moon phase; for gardeners, photographers and anyone who plans around full moons.
  • Current moon phase · embed: https://embed.widget.diy/23rTgjvz — the phase disc alone, as a quiet ambient element.

How to embed a calendar in Notion

  1. Copy the embed URL from the widget's detail page.
  2. In Notion: /embed, paste, resize to taste.
  3. The calendar rolls over at midnight by itself — every view reloads the live source page.

HTML:

<iframe
  src="https://embed.widget.diy/TnQ8XnBs"
  width="400"
  height="400"
  frameborder="0"
  scrolling="no"
  loading="lazy"
></iframe>

Why not Notion's native date properties?

Notion dates are database fields: perfect for deadlines, useless for "what does this month look like". A live calendar widget gives you the visual month grid — lunar dates and holidays included — that Notion's tables can't render.

FAQ

Do lunar calendars update for leap months? Yes — the source almanac pages carry the full lunar computation; the embed shows whatever they show, live.

Can I crop just this week's row? Yes: when creating a widget, drag the frame around exactly the region you want — a single week, a single day cell, or the whole month.

Free to embed? Yes, all plaza widgets embed free and unlimited.
