Google Calendar Event Creator

           

Install from the Chrome Web Store →

A Chrome extension that adds a toolbar button which, when clicked, reads event details from the current web page and shows a small popup listing what was found — one button per event when the page describes several. Clicking a button opens a pre-filled Google Calendar event (via https://calendar.google.com/calendar/render?action=TEMPLATE) — no API keys or OAuth needed. You review the pre-filled event and hit Save.

What it extracts

• Event name (text)
• Date and time (dates) — timed, all-day, or omitted if none found
• Location (location)
• Details (details) — the event description plus a link back to the source page

An event is created with whatever subset of these is available; missing fields are simply left for you to fill in on the Google Calendar screen. For how the details are scraped from a page, see dev/procedures/highLevelDesign.md.

Install

Install from the Chrome Web Store →

Or load the latest development build:

1. Download the latest release zip and extract it — it unpacks to a folder with manifest.json at its top.
2. Open chrome://extensions, enable Developer mode (top right), click Load unpacked, and select that folder.

To pick up a later release, download the new zip, extract it over the same folder, and click the refresh icon on the extension's card in chrome://extensions. If you're working on the extension, clone the repo instead and Load unpacked the extension/ subfolder of the working tree (that's the extension root — everything else in the repo is tests, fixtures, and tooling) — or run npm run build to produce the very same dist/google-calendar-event-creator.zip the release serves.

Releasing

The version users see is extension/manifest.json's version. Merging a version bump to main cuts GitHub Release vX.Y.Z with google-calendar-event-creator.zip attached, and the daily auto-release ships shipped-file changes to the Chrome Web Store on its own (patch-bumping as needed).

Use

Navigate to a page describing an event and click the extension's toolbar button. A small popup opens with a button for each event found on the page, showing its title, date/time, and location. Click the event you want to open a new tab with the Google Calendar "create event" screen pre-filled; review and save.

Privacy

The extension collects, stores, and transmits nothing — all processing happens locally in your browser and it makes no network requests of its own. See the privacy policy for the full policy (also published at https://missingbulb.github.io/GoogleCalendarEventCreator/privacy/).

Permissions

activeTab and scripting: the extension can read a page solely when you click the button on it, and sends nothing anywhere — it just opens a Google Calendar URL in a new tab.

declarativeContent: lets extension/icon/toolbar-icon.js ask the browser to show a green toolbar icon on hosts we explicitly support (e.g. meetup.com), a gray icon on unsupported "news"-type sites, and the default blue icon elsewhere — matched by host pattern inside Chrome. The extension never reads your tabs' URLs, so it requests no "tabs"/browsing-history access.

• Requirements — the numbered, executable requirements spec (popup UI, toolbar icon, extractor support, and product behavior), each leaf backed by a case.
• High-level design — how extraction works.
• File descriptions — the per-file map.
