About this tool.
SDAweb Calendar Sync turns any Google Calendar into a polished, on-brand events display on your WordPress site — without duplicate data entry. Keep scheduling in Google Calendar the way you already do; the plugin pulls those events in and keeps your site in sync automatically.
It’s for anyone who already runs their events in Google Calendar and wants them to look like a native part of their site instead of an embedded iframe — businesses, teams, venues, clubs, communities, and organisations of every kind.
Insert a calendar with a Gutenberg block, a shortcode, or a classic widget. All three share one render pipeline, so the output is identical however you add it.
Six ways to show your calendar
List / Agenda — chronological, optionally grouped by day, week, or month
Month grid — classic 7×6 calendar with multi-day event ribbons spanning across cells, today highlight (cell or whole-column style), optional ISO 8601 week-number column, and per-feed pastel chips
Card grid — upcoming events as styled cards, responsive
Week — 7 day columns, today highlighted
Day — single-day agenda
Mini-month — compact dot-density grid for sidebars and widgets, with a tap-to-expand event panel showing today + next upcoming events and a “Load more” button
Switch between views with one setting, or expose a visitor-facing view-toggle pill so visitors can switch themselves. Under the hood every view shares the same data layer, the same CSS-variable system, and the same accessibility baseline.
Smart UX out of the box
Hover popover on event chips (Month, Week, Mini) — a floating card with date, time, location, calendar, recurrence summary, and a click-through link, so visitors get the full event detail without leaving the page. Desktop hover + keyboard focus only; touch users keep direct click-through.
Mobile auto-degrade Month → Mini — below ~600px the full grid is replaced by the compact Mini-month view, so phone visitors get a clean, tappable calendar with no extra work from you. One wrapper, two layouts, no JS swap.
ICS subscribe dropdown — one tap to add your events to a visitor’s own calendar: Google Calendar (web), Apple Calendar / Outlook (webcal), Android Google Calendar app (intent), and Copy-link with toast confirmation. Mobile becomes a bottom sheet.
Live search + jump-to-date picker — optional chrome controls so visitors can filter or navigate quickly.
Multi-day event ribbons — week-spanning bars with arrow indicators when an event continues beyond the visible row.
Recurring event indicator — small ↻ icon with a plain-language cadence summary in the tooltip (“Repeats weekly until 31 December 2026”).
Per-display locale override — render a calendar in a specific language (e.g. nb_NO) even when the site language differs, so you can run a localized calendar on a site that’s in another language.
Two authentication paths
API key — for calendars marked “Make available to public” in Google Calendar. One field, paste, done.
Service Account JSON — for private calendars without per-user OAuth. Upload the JSON, share the calendar with the service-account email, you’re set.
Credentials are encrypted at rest using a key derived from your site’s authentication salt. They are never echoed back into the admin UI — only the masked value and (for service accounts) the public service-account email are shown.
Theme-aware out of the box
The plugin reads your active theme’s theme.json color palette and uses your primary , accent , foreground , and background colors automatically. Per-display overrides let you set custom primary, accent, today-highlight, and link colors and force light/dark mode without touching code. Every design token is exposed as a CSS custom property so a developer can fully restyle the calendar from their theme stylesheet.
Five built-in theme presets
One-click coordinated colour bundles: Default (clean blue), Warm earth (cream + deep red), High contrast (solid black on white for AAA-stricter sites), Forest (deep green), Sunset (warm coral + amber).
Accessibility built in
WCAG 2.2 AA baseline with several AAA touches:
Live contrast warnings on every colour picker — the admin UI shows the WCAG ratio against both light and dark surfaces with pass/fail markers as you choose colours
Automatic high-contrast overlay via prefers-contrast: more
Focus-visible halo: a 4px white ring behind the primary outline so focus stays visible against any chip background
prefers-reduced-motion honored everywhere
ARIA roles and labels on the month grid, navigation, popovers, and view-toggle
Semantic HTML throughout
RTL-aware via CSS logical properties
Tabular numerals for day numbers and time labels so single- and double-digit values don’t drift
Built for the WordPress.org standard
Block editor first-class — server-side rendered, ServerSideRender preview, all the standard InspectorControls
Shortcode and classic widget on the same render pipeline
No bundled core libraries (no jQuery on front-end, no Guzzle, no Carbon, no Monolog)
No third-party authentication relay — your credentials only ever talk directly to googleapis.com
Translation ready via translate.wordpress.org once the plugin is published and indexed (no bundled .po / .mo — WordPress auto-loads locale files into wp-content/languages/plugins/ per the WP Plugin Handbook), plurals via _n() , JS strings via wp_localize_script
Free and GPLv2
For developers
Extension hooks are documented in docs/hooks.md inside the plugin folder. The first-release set includes filters for event data, event URLs, query args, cache TTL, render output, palette resolution, plus actions for refresh and uninstall lifecycle.
Third-Party Services
This plugin connects to the Google Calendar API to retrieve events from calendars you configure.
Service: Google Calendar API v3
Website: https://developers.google.com/calendar
Terms of Service: https://developers.google.com/terms
Data sent: the calendar ID(s) you configure, plus either your API key or a JSON Web Token signed with your service account credentials. Event data is returned to your server and cached locally as WordPress transients. No event data is sent to any third party.
The ICS subscribe feature, when enabled, serves a self-hosted iCalendar (.ics) feed from your own site — built from the same calendar data already fetched via the Google Calendar API above — so subscribers can add it in Google Calendar, Apple Calendar, Outlook, or any other app that supports calendar subscriptions. No data is sent to any third party beyond the Google Calendar API connection already disclosed.

Frequently asked questions.
Do I need a Google account to use this plugin?
You need a Google Cloud project to generate either an API key (for public calendars) or a service account (for private calendars). The plugin’s Help tab walks you through both setups in 7–8 steps each. Setup is one-time per site.
Does this plugin send my data anywhere other than Google?
No. Calendar data is fetched directly from googleapis.com using the Google Calendar API. The plugin does not contact any SDAweb-controlled servers, analytics endpoints, or third-party relays. There is no telemetry.
Can I display a private (non-public) calendar?
Yes. Use the Service Account authentication option. The plugin shows you the service account email; share your private calendar with that email in Google Calendar’s sharing settings, and the plugin can read it.
How often does the plugin refresh events?
A WP-Cron job refreshes registered calendars in the background every 15 minutes. Cache lifetime is configurable upward in the plugin settings (15 minutes is the enforced minimum). You can also click “Refresh now” on any calendar in the admin to fetch immediately.
Does it work with caching plugins?
Yes — the calendar HTML is part of the page output, so any page-cache plugin caches it like any other content. The cache will refresh on its own schedule. If you need immediate refresh after a calendar change, purge the page cache.
Can I add multiple calendars to one display?
Yes. Each display picks one or more registered calendars and merges them. Events are color-coded by calendar. A multi-feed legend strip can be enabled above the events; chips can be styled solid (single-feed) or pastel (multi-feed legibility).
Will it work with my theme?
The plugin reads your active theme’s theme.json color palette automatically, so calendar colors match the site by default with zero configuration. If you use a classic theme without theme.json (or want to override), every color is exposed as a CSS variable that you can override from your theme stylesheet. Five built-in theme presets give you coordinated palettes with one click.
Is the plugin accessible?
Yes — built-in. WCAG 2.2 AA baseline includes prefers-reduced-motion and prefers-contrast: more support, :focus-visible outlines with a white halo (visible on any background), ARIA labelling on the month grid, navigation, popovers, and view-toggle, semantic HTML throughout, RTL-aware via CSS logical properties, and live contrast warnings in the colour-picker UI as you choose values.
Can I show the calendar in a different language than the rest of the site?
Yes. Each display has an optional Locale override field — set it to nb_NO , sv_SE , etc. and that calendar renders weekday names, month names, and built-in labels in that language regardless of the site’s language. Useful when an English site hosts Norwegian-audience content.
Where are the extension hooks documented?
In docs/hooks.md inside the plugin folder. The plugin commits to keeping documented hooks stable within a major version.
